UT309 series professional infrared thermometers can determine surface temperature through measuring infrared energy radiated by the target surface. It is designed to meet one of the highest protection ratings in UNI-T’s product line, with IP65 and 3m drop proof. With a rapid response rate of 250ms, high measuring accuracy and multiple scanning modes, UT309 proves to be necessary tool for engineers and technicians working in avarious fields such as electrical distribution inspection, HVAC maintenance, transportation equipment inspection and instrument repair etc.

 Models in UT309 Series: UT309A, UT309C, UT309E

● High/Low temperature alarm with LED indication
● Lock measurement
● Data hold/auto power off
