The ZDZ-52P resistance vacuum gauge can be connected to two resistance gauges and has a maximum of four-way relay control outputs. It also has functions such as analog output and serial communication. It is suitable for the measurement and control of medium and low vacuum.
The resistance gauge adopts the constant temperature measurement method for measurement, which features high precision and a fast response. It uses a fully digital calibration method, and calibration can be completed without the need for tools. The instrument is equipped with an aluminum alloy casing, which is sturdy and reliable and has good electromagnetic shielding performance, making it suitable for use in harsh industrial environments.
