IT-540 Series Non-Contact Infrared Thermometers
Overview
The hand-held IT-540 Series of non-contact thermometers include six models. The various options offer versatility in measurement ranges, target areas and target distances as well as choices to include a target marker or without a target marker for all budgets. The non-contact thermometer allows for temperature measurement in dangerous applications such as monitoring abnormal heat generation in high-temperature voltage transformer equipment, power supply panels, quick and accurate hygienic monitoring of the storage temperature of food products. Measurements are instantaneous and accurate.
