Extech PRC20 Thermocouple Calibrator
The Extech PRC20 is a versatile handheld calibrator designed to source and measure eight thermocouple types (J, K, T, E, C, R, S, and N). It provides precise output displayed in degrees Celsius (°C), degrees Fahrenheit (°F), or millivolts (mV), making it ideal for calibrating thermometers, transmitters, controllers, and recorders. With features like a large backlit LCD, user-adjustable calibration presets, and Cold Junction Compensation (CJC), the PRC20 ensures accurate and reliable performance in both laboratory and field applications.
Description
The Extech PRC20 Thermocouple Calibrator is engineered to simulate and measure outputs for a wide range of thermocouple types, providing high accuracy for calibration tasks. Its palm-sized, double-molded housing ensures durability and portability, while the large dot-matrix digital backlit LCD offers clear visibility in various lighting conditions. The device supports Cold Junction Compensation (CJC) to enhance measurement accuracy, and it includes up to five user-adjustable calibration presets for convenience. The PRC20 operates on a large battery bank, offering extended work cycles, and comes with a comprehensive kit that includes calibration cables, an AC adapter, batteries, and a hard carrying case.
