Temp Stick PRO NIST Sensor with Buffer Bottle
Which Temp Stick to Use:
Pacific Biomedical lists three Temp Stick sensors. They are not the same part. This page is the sensor and the glycol bottle together.
- Temp Stick WiFi sensor, PB-TEMPSTICK. Air temperature and humidity only. No NIST certificate, no probe, and no glycol bottle. Use it in a medication bag, a cabinet, or a room where the air reading is what you need. It runs on two AA batteries and does not alert on a power outage.
- Temp Stick PRO NIST sensor with buffer bottle, TEMPSTICK-PRO-RX-NIST. This page. The sensor and the glycol bottle together. NIST certificate included. The bottle probe reads -55 F to 140 F and follows the liquid, so a door opening moves the reading less than an air sensor does. Use it in a Helmer refrigerator or in a freezer that holds blood products, blood-product storage accessories, or other sensitive medications or fluids inside that range. It does not cover an ultra-low freezer at about -80 C. The AC adapter and 6 ft power cable are included, along with two AA batteries.
- Temp Stick PRO with NIST, TEMPSTICK-PRO-NIST. The sensor and an open T-type metal probe. NIST certificate included. The probe reads -238 F to 500 F. Use it when the point you need is outside the bottle range, or when the procedure calls for a metal tip. The AC adapter is included. This listing does not include the glycol bottle.
Pacific Biomedical does not list the Temp Stick +Power model, the classic sensor with a NIST certificate, or the +Power NIST model. Those are different manufacturer parts.
Sensor and Buffer Bottle Highlights:
- This listing is the Temp Stick PRO sensor plus the glycol buffer bottle, part TEMPSTICK-PRO-RX-NIST.
- Glycol bottle probe: -55 F to 140 F (-48 C to 60 C), accuracy ±0.5 C, cable 6.5 ft.
- Fill listed on the product page: 60 percent propylene glycol and 40 percent deionized water.
- Ambient range: -40 F to 140 F (-40 C to 60 C), accuracy ±0.15 C. Humidity 0 to 100 percent RH, accuracy ±3.0 percent RH.
- The Temp Stick product page says the glycol bottle has more thermal mass than air, so it changes temperature more slowly and follows blood products, medications, or fluids more closely than an air reading.
- Alerts for temperature, humidity, probe temperature, heat index, dew point, low battery, WiFi loss, and power loss. Methods are text message, email, and the app.
- The AC adapter is included with TEMPSTICK-PRO-RX-NIST, along with two AA batteries. On AC power, the sensor uses the adapter first and switches to the batteries if power drops.
- Battery life is stated as more than a year at typical settings. No Ethernet port. WiFi only, 2.4 GHz.
- Black. Three-year limited warranty.
Helmer Refrigerator and Freezer Monitoring:
Place the glycol bottle in a Helmer refrigerator, or in a freezer used to manage blood products, blood-product storage accessories, or other sensitive medications or fluids. The bottle probe is rated from -55 F to 140 F. Buying the sensor does not accredit the service.
CAMTS standards for medical transport, in the 2023 Special Operations and Medical Retrieval edition, say storage of medications must allow protection from extreme temperature changes when the environment requires it. If a refrigerator for medications is on the vehicle, those standards require a temperature monitoring and tracking policy, and the refrigerator is to be used and labeled for medication use only. When a service stores blood products, the same standards call for continuous refrigerator temperature readings, an audible alarm if the temperature leaves range, daily checks of the monitoring equipment, and a written procedure for an out-of-range temperature.
The buffer bottle records the liquid temperature and sends text, email, and app alerts. A blood bank or a transport program can use that record for a Helmer refrigerator, a blood-product freezer, or the storage used with blood-product accessories. The sensor does not replace the daily check, the written procedure, or an audible alarm when the standard asks for one.
For ground ambulance accreditation, the American Ambulance Association points services to CAAS standard 203.03.04. That standard, as the Association describes it, calls for a policy on storing medications and IV fluids so they are protected from extreme temperature changes, and a procedure for what to do if they are exposed. Temperature and time monitoring is one practical measure the Association names. This bottle is one way to log a refrigerator or freezer and to notify people when a limit is crossed.
NIST's vaccine-storage guidance describes a digital logger whose probe sits in a liquid-filled bottle, so the reading follows the stored liquid rather than the air in the cabinet. This product is that kind of bottle. Those guidelines also describe a display, a stored reading history, and alarm behavior. This page does not claim the Temp Stick meets each of those items.

Questions:
Does TEMPSTICK-PRO-RX-NIST come with an AC adapter?
Yes. TEMPSTICK-PRO-RX-NIST includes the AC adapter and the 6 ft power cable, plus two AA batteries. On AC power, the sensor uses the adapter first and switches to the batteries if wall power drops.
What is the Temp Stick PRO buffer bottle with NIST?
It is the Pacific Biomedical Temp Stick PRO sensor and the glycol buffer bottle together, part TEMPSTICK-PRO-RX-NIST. The bottle is not a separate accessory. A NIST calibration certificate from an ISO 17025 accredited laboratory is included. Pacific Biomedical supplies the pair for Helmer refrigerators and for freezers used to manage blood products, blood-product storage accessories, and other sensitive medications or fluids.
Why use a glycol bottle instead of an air sensor?
The Temp Stick product page says the glycol bottle has more thermal mass than air, so it responds more slowly and follows blood products, medications, or fluids. NIST vaccine-storage guidance describes the same idea: put the logger probe in a liquid-filled bottle so the reading tracks the stored liquid. A door opening then has less effect on the logged temperature than it does on the air.
What is in the glycol bottle?
The product page lists the fill as 60 percent propylene glycol and 40 percent deionized water. The bottle probe range is -55 F to 140 F, with accuracy ±0.5 C, on a 6.5 ft cable.
Is this the open T-type probe for a freezer?
No. This part is the glycol buffer bottle, TEMPSTICK-PRO-RX-NIST. Use it in a Helmer refrigerator or in a freezer that holds blood products, blood-product storage accessories, or other sensitive medications or fluids. The bottle is rated from -55 F to 140 F. The open T-type probe, part TEMPSTICK-PRO-NIST, is a different model, rated from -238 F to 500 F, for a metal tip in more extreme heat or cold.
Is there a subscription fee?
The Temp Stick product page states that unlimited data logging and the text, email, and app alerts stay free for the life of the sensor. You pay for the sensor and the buffer bottle together. Re-certification of an existing sensor is a separate service, not a monitoring subscription.
Does it use 5 GHz WiFi or Ethernet?
No. The Temp Stick connects only to 2.4 GHz WiFi. There is no Ethernet port. It can join a mobile hotspot. The Temp Stick instructions warn that an iPhone or iPad hotspot often shuts off after a short idle period, so that hotspot is a poor long-term source.
Does it have an audible alarm?
The Temp Stick product page describes the sensor as a silent alarm. Alerts leave the sensor by text message, email, and the app. A CAMTS blood-storage policy that requires an audible alarm still needs that alarm. This sensor and bottle can be the continuous recorder and the remote alert beside that requirement.
Can this support a CAMTS medication refrigerator policy?
CAMTS medical-transport standards require a temperature monitoring and tracking policy when a medication refrigerator is on the vehicle. This bottle can take the liquid reading and send the alert inside that policy. It does not accredit the program, and it does not replace the label for medication use only, the daily check, or the out-of-range procedure.
Can this support CAAS ambulance medication storage?
CAAS standard 203.03.04, as described by the American Ambulance Association, requires a policy that protects medications and IV fluids from extreme temperature changes, and a procedure if they are exposed. A service can place this bottle with the medications in the refrigerator and keep the log. The policy and the response to an excursion remain the service's work.
What does the NIST certificate mean?
The sensor ships factory calibrated, with a NIST calibration certificate for that certification option. In the account, an offset can be added so the display matches another instrument. Alerts use the offset reading. The certificate pictured on this page is a sample layout. The dates and measured points on that sample are not the certificate for the sensor you receive.
Why might the first readings look wrong?
The PRO setup guide linked from this product says the first readings can be off by about 10 degrees until the first-hour calibration finishes. After that hour, readings follow the published accuracy.
What happens when WiFi or power fails?
If WiFi drops, the sensor keeps logging and uploads when the connection returns. You can turn on an alert for the loss and the return. On the included AC adapter, a power cut moves the sensor to its AA batteries, and you can alert on the outage and the recovery. The stated WiFi range is 300 to 400 ft with a clear path. The 6.5 ft cable lets the bottle stay in the Helmer refrigerator or freezer while the sensor stays outside the cabinet.
Can I download the temperature history?
Yes. The Temp Stick product page says the history can be exported as a CSV file, and temperature and humidity reports can be emailed daily, weekly, or monthly. Alert schedules can arm and disarm alerts. The anti-false-alarm setting is meant to skip alerts during brief high-traffic periods. A public API is documented in the account.
What brand is this Temp Stick?
The brand is Pacific Biomedical. This listing is the Temp Stick PRO sensor together with the NIST calibrated glycol buffer bottle, part TEMPSTICK-PRO-RX-NIST. It is made in America and carries a three-year limited warranty.
