Description
This portable process calibrator provides stable and accurate signal testing for industrial work. It measures and sources 4–20 mA loops, DC voltage, thermocouples, and frequency signals. With ±0.025% mA accuracy and 1 μA resolution, it helps technicians verify transmitters, PLC inputs, and controllers with confidence.
The unit includes safety warning beepers for open and short circuits. It supports K, J, E, and T thermocouples with 1°C / 1°F resolution across a wide temperature range. The calibrator also generates frequency signals up to 62.5 kHz. Its compact body and light weight make it easy to carry to job sites. A 9V battery and external pack option ensure reliable field operation.
