Extech PRC10 Current Calibrator/Meter

The PRC10 is built to provide precision current sourcing and measurement in a handheld package. In source mode, it can generate currents from 0 to 24 mA (−25 % to +125 % of nominal) even when driving loads up to 1,000 Ω. In measure mode, it reads DC currents up to 50 mA (−25 % to +230 %). The device also includes a built-in 24 V DC loop power source so that two-wire current loops can remain active during tests.

Housed in a durable, double-molded enclosure, the calibrator features a large, backlit dot-matrix LCD and standard banana I/O ports for connectivity. It supports up to five user-programmable calibration presets, enabling quick recall of common settings. For long-term or continuous use, the unit can be powered via an external adapter or rely on its internal battery bank. The PRC10’s auto power-off function helps preserve battery life when idle.

Overall, this tool blends sourcing, measuring, loop power, and memory functionality into a single handheld device well suited for field calibration, maintenance, and process control work.
