This fundamental feature of our physical universe makes itpossible to be sure of the temperature of a material such as aproperly made ice bath, for example,beforeyou measure it so you can test your thermometer’s accuracy against that known temperature. To do this, you must carefully followall...
Dry blocks aren’t suitable for liquid-filled glass thermometers so the accuracy check is performed using a constant temperature fluid bath, such as the Fluke Calibration 6330. If the error of a liquid filled thermometer is large, it is best to discard the thermometer. Another option if the ...
How do I know if my infrared thermometer is accurate? To test the accuracy of an infrared thermometerrequires access to a stable surface of a known temperature. You cannot verify the accuracy of an IR thermometer by comparing it to an immersion type thermometer that is beneath the surface of...
This article summarizes what you need to verify that your Fluke 67 MAX Infrared Thermometer is performing within its published specifications. Note that we are only talking about verifying the thermometer, not adjusting it. If your 67 MAX requires adjust
Thermometer probes like PT100s, PRTs, and RTDs need to be calibrated regularly. Temperature is always on the move through time, meaning any probes that are measuring temperature need to be calibrated to be accurate. If your work requires a specific temperature or range, then you need to be ...
See 10 steps of how to check the accuracy of an infrared thermometer designed for measuring human body temperature. Learn best practices & how things work.
Verify clean coils and correct airflow prior to charging. Attach a high accuracy digital gauge like the iManifold or Testos or FieldPiece SMANs to the service ports. Make sure the gauge has been zeroed, if required barometric pressure offset adjusted to current conditions, and the proper refrig...
Check pin connections: Verify that pins are correctly connected to the circuit and that there are no loose connections or short circuits. Measure MOSFET voltage: Measure the voltage at the MOSFET gate, drain, and source terminals and compare the results to the specifications in the datasheet. If...
Attach the inflation bulb.Connect one hose to the inflation bulb by placing the open end of the hose over the connector and pushing it down until it is secured. Gently tug on the inflation bulb to verify that it is secured to the hose. The inflation bulb can have either a lever or scr...
This leads to a situation where the laboratory staff may take the rather unscientific approach of changing the position of the thermometer in relation to the flat plate until they find the “sweet spot” where the thermometer passes calibration. This is not good metrology. To solve thi...
