The Klein Tools CL320KIT HVAC Electrical Test Kit provides a set of three tools for HVAC professionals. The Klein Tools CL320KIT features the CL320 HVAC Clamp Meter that is an auto-ranging TRMS digital clamp meter that measures 400A AC, DC microamps and temperature. The CL320 comes with test leads with CAT III/CAT IV safety caps, and a K-Type thermocouple probe. This HVAC Test Kit also features the IR07 that is a dual IR (infrared) and probe thermometer that measures temperature from -40 to 572F (-40 to 300C). The IR probe accurately measures surface temperature with a distance to spot ratio of 8:1. The probe measures air and liquid temperature (T1-T2). Users of this test kit also provides users with the NCVT-3P dual range non-contact voltage tester with a flashlight that detects low and standard voltage from 12 to 1000 V AC or 70 to 1000V AC for a broad range of applications.
