Description
Overview
GAOTek handheld process calibrator is a high-precision handheld signal measurement or output instrument that can simultaneously measure and output various industrial process signals such as voltage, current, resistance, frequency, thermocouple, thermal resistance, etc. It is equipped with an external high-precision intelligent pressure module for on-site calibration of pressure transmitters.
Features
- Super strong protection function
- Thermal resistance and thermocouple are simulated in the form of temperature
- Can simulate a two-wire transmitter
- Two isolated channels support
- Can provide manual step, automatic step
- Manual backlight adjustment
- Automatic power-off function
- Suitable for field use
- Provide DC 24 V circuit power supply calibration
