Digital Multimeter UNI-T UT71D - description: 

UNI-T UT71D digital multimeter measures AC/DC current and voltage, resistance, capacitance, frequency, temperature (ºC and ºF), duty cycle, and tests diodes and continuity.

Please note that the standard temperature probe from the multimeter package contents allows measuring temperature up to 300 ºC. In case you require measuring temperatures above that value, please, buy Uni-T UT-T03 Temperature Probe.
