Why is my Calex PyroUSB Thermometer showing inaccurate temperature readings?
- LLinda McdonaldOct 30, 2025
If your Calex Thermometer shows an inaccurate measured temperature, several factors could be the cause. First, the target might be too small for the sensor’s field of view; ensure the sensor's view is completely filled by the target, position the sensor closer to measure a smaller area, and make sure the target is at least twice the size of the measured spot. Second, if the target is a reflective metal surface, measure a non-reflective area, or paint or coat a measurable area to make it non-reflective; for 2.2 µm models, try changing the emissivity setting. Also, check for any field of view obstruction and remove it to ensure the sensor has a clear view of the target. Ensure the lens is clean and dry; clean gently with a soft lens cloth and water, and if the problem recurs, consider using ...
