Infrared Thermometer (IRT-BTA, discontinued)

Specifications and User Guide

Troubleshooting

  • Primary Test: Press the MEAS button on the device. Does it turn on? Point the device at at tabletop or wall. Does it display a reasonable room temperature?
  • Secondary Test: Use a thermometer to measure the temperature of a cup of water, and then use the IRT-BTA to measure the temperature of the cup of water. Are the measurements comparable?
