Frequently Asked Questions

If the probe thermometer is placed in water or air, remove it from the water and compare the temperature in a controlled environment (like inside your house) and compare with a red spirit thermometer.

Mercury or red spirit thermometers are very accurate. Inside your house, place a red spirit thermometer next to the digital thermometer. The thermometers should agree within 2 degF.

Here is an example of a red spirit thermometer on Amazon:

They are also available in local hardware stores.

Other Useful Info:

1. If the sensor is separate, place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.
2. If the sensor is placed in water, the body may have a temperature gradient and the sensors may be at different depths.
