Extech PRC15 – Precision Current and Voltage Calibrator/Meter with 24V Loop Power

The Extech PRC15 is a high-accuracy, palm-sized calibrator and meter designed for sourcing and measuring both DC current (0–24 mA) and DC voltage (0–20 V) signals used in industrial process control systems. It features ±0.01% accuracy, five user-definable calibration presets, and a built-in 24V loop power supply for powering 2-wire transmitters during calibration. With a large backlit dot-matrix LCD, standard banana I/O ports, and extended runtime from a 6xAA battery bank (or included universal AC adapter), the PRC15 is ideal for field technicians, instrument engineers, and calibration labs requiring reliable, portable simulation and measurement of 4–20 mA and 0–10 V process signals.

Features

• Sources 0 to 24 mA (–25% to 125%) and 0 to 20 V DC with ±0.01% accuracy
• Measures 0 to 50 mA current and 0 to 19.99 V voltage
• Built-in 24V DC power supply for 2-wire loop devices
• Large backlit dot-matrix LCD for clear readout
• Up to five user-adjustable calibration presets for quick setup
• Standard banana input/output ports
• Extended battery life with 6 x AA batteries; universal AC adapter included for continuous use
• Rugged double-molded housing for field durability
• Complete with test leads, alligator clips, universal AC adapter (100–240V), 6 AA batteries, and hard carrying case
