RECOMMENDATION: For all Microtherm products, samples calibrated at the desired temperature should be tested in the application before regular use, to ensure that the thermal Protection, Regulation, Control or Sensing/Signaling specifications are met. In case an adjustment is needed, we recommend new samples to be tested.
