Extech PRC10 – Precision Current Calibrator/Meter with 24V Loop Power

The Extech PRC10 is a compact, palm-sized current calibrator and meter designed for field and bench calibration of 4–20 mA process devices such as transmitters, transducers, controllers, and indicators. It sources 0 to 24 mA (–25% to 125%) with high accuracy (±0.01% ±1 digit) and includes a built-in 24V DC power supply to energize 2-wire current loops—eliminating the need for external loop power. Featuring a large backlit dot-matrix LCD, five user-definable calibration presets, and extended battery life from a large internal battery bank, the PRC10 is ideal for process control technicians, instrument engineers, and maintenance professionals requiring reliable, portable calibration in industrial environments.
