Extech PRC15

For engineers and technicians working in process control, instrumentation or automation, the Extech PRC15 provides a versatile handheld solution that solves the common challenge of calibrating sensors, transmitters, recorders and controllers in the field or on the bench. Whether you need to source a 4–20 mA signal to test a controller input, simulate a transmitter output, or measure an unknown signal from a process device, the PRC15 supports these tasks with precision and flexibility. Its ability to operate both on six AA batteries and via a 100‑240 V AC adapter ensures it keeps up during extended use or mobile deployments. The large backlit dot‑matrix LCD makes reading values in dimly lit control rooms straightforward. The inclusion of five user‑adjustable presets allows you to quickly load frequently used calibration points, saving time and reducing setup errors. Compared with bulky calibrators or separate current/voltage meters, the PRC15 combines multiple functions into one portable instrument, making it ideal for industrial service teams in Bangladesh where space‑constrained work‑sites or field service calls demand compact and robust tools. If you need to implement a calibration program or perform urgent field checks without carrying multiple devices, the PRC15 stands out as a smart choice.
