Cleaning and Caring for Your Infrared Thermometer

To be accurate, infrared thermometers must be kept free of dirt, dust, moisture, fog, smoke and debris. When such conditions are present, you may want to consider using another tool for measuring surface temperatures such as a surface temperature probe and meter (like a MicroTherma 2 with a Precision Surface Probe).

Always take the time to clean your infrared thermometer after exposure to dirty, dusty, smokey or humid conditions. You should also plan a regular cleaning every six months or so. Particular care should be taken to keep the infrared lens or opening clean and free of debris.

To clean your infrared thermometer:

  1. use a soft cloth or cotton swab with water or medical alcohol (never use soap or chemicals)
  2. carefully wipe first the lens and then the body of the thermometer
  3. allow the lens to dry fully before using the thermometer

Never submerge any part of the thermometer.

Store your thermometer between 40°F and 149°F (4-65°C). Use care to protect it from extreme temperatures while in storage.

Also use care to protect your infrared thermometer from drops or shocks. Handy lanyards or wrist-straps are available for some units.
