Quick Overview

Why Does BRS Recommend This?

The exact thermometer we use to calibrate our temperature probes, heaters and any other device that requires calibration. We will usually double check calibration with the VWR Thermometer about once a month, and you may be surprised what you find with your probes or heaters calibration over time.

Fully Calibrated using instruments traceable to the National Institute of Standards and Technology

There has never been an easy and precise way to calibrate temperature probes since most thermometers are made cheaply and are very unreliable. With the VWR Long-Stem Traceable Thermometer, you can accurately calibrate your temp probe or other temperature sensing devices. The thermometers are all individually certified and guaranteed to be accurate within ±0.2°C @ 25°C.

  • Calibration Certificate Included

  • Reliable & Accurate

  • 8" Long Probe

  • Armored Guard Included

  • Reads in Celcius or Fahrenheit

  • Easy to Read LCD Display

Full Details

Temperature probes have always been one of those things in the hobby that you pay 40-60 dollars for the probe but calibrate it with a thermometer that you have had laying around for ten years that only cost you 2 bucks. In most cases, we find that using multiple (3 or 4) thermometers was the only way to calibrate a temp probe semi-accurately until we came across these.

We have found most temperature sensing devices could be off anywhere from one degree all the way up to 8 degrees from the stated temperature. The Traceable Long Stem Calibration Thermometer will let you properly calibrate your temp probes accurately and keeping the ecosystem at a proper temperature. It is recommended to have it recertified every two years from the certification date keeping the readings accurate.



  • Resolution - 0.1° above -20°C and below 200°C
  • Sampling Rate - 1 second in °C mode / 10 seconds in °F mode
  • Range - -50 to 150 °C / -58 to 302 °F
  • Accuracy - ±0.2 °C at testing points
  • Stem Length - 8"
  • Overall Length - 11"
  • Stem Diameter - 1/8"
  • Overall Diameter - 1.2"


We do not recommend leaving this particular thermometer in the water long term as it is not designed to be used as a temperature monitor. It is best practice to place the thermometer in the tanks water, next to the probe you wish to calibrate for about 10 minutes, then turning the calibration thermometer on and proceeding with calibration of the probe.

  • Apex was so far off By Bob on 2/17/2017

    Great having a validated reference temperature. In reef keeping +/-2 degrees is a big change, especially if you're not confident of which side of the spectrum you're on.
  • Great way to calibrate your probe By Davide on 1/29/2017

    Very easy to use and accurate. I recommend this product to calibrate your temperature probe every so often. Stable temperature is vital to success of a reef system!
