## Description

Lighten your load by taking the TechChek to every site. It’s like bringing a cartload of test equipment from the shop to the control room or the field. The TechChek 820 sources & reads DC like a milliamp or voltage calibrator, simulates and measures T/Cs & RTDs like a temperature calibrator and generates and counts frequency & Counts-Per-Minute like a frequency calibrator. Your TechChek can also help you trouble shoot like a multimeter! It checks continuity and measures AC line voltage without carrying a separate instrument. The TechChek 820 is easy to use. Select a function, choose a range, and turn the knob for the precise output you need. Plus, you can store three output values per range for instant recall with the QUIK-CHEK switch.
