600V AC/DC True RMS HVAC Digital Multimeter - 

The Fluke 116 digital multimeter delivers the capabilities professionals demand to troubleshoot and repair HVAC (heating, ventilation and air conditioning) systems. It has everything you need in an HVAC meter, including temperature and microamp measurements to help you quickly troubleshoot problems with HVAC equipment and flame sensors. The Fluke 116 comes with the Fluke 80BK-A integrated DMM temperature probe. The microamp function allows flame sensor measurement down to 0.1 microamps. The AutoV/LoZ function prevents false readings caused by ghost voltage. The Fluke 116 also has a large white LED backlight for work in poorly lit areas. It measures resistance, continuity, frequency, and capacitance and provides Min/Max/Average readings with elapsed time to record signal fluctuations.
