product overview

The ZDZ-52D resistance vacuum gauge can connect two resistance gauges and control up to four relay outputs. It also has functions such as analog output and serial communication. Suitable for measurement and control of medium and low vacuum.
The resistance gauge measurement adopts the constant temperature measurement method, which has high accuracy and fast response. Adopting a fully digital calibration method, the calibration of resistance gauges can be completed without the need for tools. The whole machine adopts an all aluminum alloy casing, which is sturdy and reliable, with good electromagnetic shielding performance, and can be used in harsh industrial environments.
