Description

The HCAL-720 RTD Calibrator is a handheld precision calibrator for Resistance Temperature Detector (RTD) sensors. It can measure and simulate multiple RTD types (2, 3, 4 wire) and resistance values, with selectable °C, °F, or ohms units and a large 5-digit LCD for clear readings.

Designed for field and workshop calibration of RTD transmitters, sensors, and associated instruments, it provides a compact, easy-to-use solution for on-site calibration and troubleshooting.

Typical applications
  • Calibrating RTD transmitters, sensors, and temperature measurement loops in industrial process control.
  • Simulating RTD signals to verify instrument inputs such as temperature controllers, recorders, PLCs, and data acquisition systems.
  • Commissioning and maintenance of temperature measurement hardware using resistance-based sensors.

This product can be supplied with a calibration certificate.

Please note: 6 x AAA batteries are not supplied with the unit
