The HCAL2 Multi-Function Temperature Calibrator is a high-precision, hand-held calibrator for the calibration and troubleshooting of process control instrumentation.
The HCAL2 simultaneously measures and sources ten types of thermocouples and seven resistance temperature detectors (RTD), whilst automatically capturing the calibration results. It measures milliamps whilst sourcing or simulating millivolts, thermocouples, RTDs or ohms to calibrate transmitters.
The logging facility stores data on the 2GB SD card supplied, which is easily downloaded to a PC via the onboard USB port and usable in most of the common spreadsheet formats. The trend feature is ideal for graphing temperature profiles and PID controller optimization with a programmable timebase. In addition, the unit has the functionality necessary to install and maintain all powered and non-powered transducers using the built-in 24V loop power supply.
Its user friendly, compact size and high precision make the HCAL2 an ideal choice for industrial field or workshop calibration. Supplied with carry case, protective rubber boot,
battery, charger, test leads, CJ compensation box and 2GB SD card.
