Lighten your load… take the TechChek 830 to every site. It’ s like bringing a cartload of test equipment from the shop to the control room or the field. The TechChek 830 sources and reads DC like a milliamp or voltage calibrator, simulates and measures T/ Cs & RTDs like a temperature calibrator, generates and counts frequency and Counts-Per-Minute like a frequency calibrator and displays pressure like a precision test gauge. Troubleshooting? It checks continuity with a beeper and measures AC line voltage like a multimeter!

Calibrate controllers, recorders and other devices in 4 to 20 or 0 to 20 mA loops. Source and read 0.00 to 24.00 mA, or Simulate a 2-Wire Transmitter. Use the optional AC adaptor for continuous operation. Display to 0.01 mA , 0.1 % of 4 to 20 and 0.1 % DP Flow. Easily calibrate 2-Wire Pressure and Electronic Transmitters by connecting the TechChek 830 to both the input and output of the transmitter. The TechChek 830 will simultaneously indicate the input and output of the transmitter on the graphical display.

Read pressure with extreme accuracy using an external QuikCal pressure module in a companion ModPak module holder. Attach the module directly to the pressure connection for the best accuracy or with optional tubing for tight spots. Display to five digits within 0.025% of reading in up to 20 engineering units including psi, pa, Kpa, Mpa, BAR, mBar, Atm, Kgf plus torr, inches and mm of mercury or water at a variety of temperatures. Each module is fully characterized for temperature and linearity to give you laboratory accuracy in the shop, control room or field.

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, R, S & N and four Pt 100 Ohm, Ni 120 Ohm and Cu 10 Ohm RTDs. Resolution to 0.1° . Cold junction compensation continuously tracks ambient temperature changes. 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) . Built-in frequency counter measures Hz, kHz & CPM.
