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 seperate 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.

Use at every point in your 4 to 20 mA loop. You can Source & Read 0.00 to 24.00 mA, Simulate a Two-Wire Transmitter or the use the TechChek 820 to simultaneously Power & Measure your Two-Wire Transmitters.

Calibrate all your DC millivolt and voltage instrumentation. Source from 0.00 to 110.00 mV and 0.00 to 10.25 V. Read up to 110.00 mV, 11.00 V and 200.0 VDC.

Source and read directly in ° C and ° F for T/ C types J, K, T & E with 1° resolution. Cold junction compensation automatically adjusts for ambient temperature changes.

Built-in Platinum 100 Ohm DIN/ IEC 751 table displays in ° C or ° F. No more decade box and hard-to-read tables. Also reads and sources in Ohms.

Generate Zero Crossing square waves from 1 to 1000 Hz, 0.01 to 10.00 kHz and from 1 to 1000 CPM ( Counts-Per-Minute) . Also measures as a frequency counter.
