UNI-T UT305C+ Infrared Thermometer

UNI-T UT305C+ Infrared Thermometer

The UT305+ series is a non-contact infrared thermometer with high precision and a high distance ratio (55:1). It has a wide temperature range (-50°C to 2200°C). Furnace kilns, heat transfer pipes, building thermal bridge effect, cold storage, greenhouses, floor heating, and other areas are all examples of equipment that can detect the thermal insulation performance.
