ZDO-54DS Thermocouple Vacuum Gauge (Refrigeration Vacuum Meter)

Product Introduction
The ZDO-54DS Thermocouple Vacuum Gauge, also known as a refrigeration vacuum meter, is a digital instrument designed for reliable low vacuum measurement and control. The system consists of a ZJ-54D thermocouple vacuum sensor and an electronic control unit.
Using a digital circuit design, the ZDO-54DS vacuum gauge provides accurate readings, a wide measurement range, fast response, and strong resistance to contamination. The thermocouple sensor is designed to maintain stable performance and reliable vacuum indication without oxidation in atmospheric conditions.
With a measuring range of 0.01–999 Pa, alarm indication, and an RS232 communication interface, this digital thermocouple vacuum meter is suitable for refrigeration servicing, electronic manufacturing, metallurgical processing, and other vacuum measurement applications.

Performance Features
• Wide vacuum measurement range from 0.01 to 999 Pa
• Digital circuit design for stable and reliable readings
• Fast response to vacuum changes
• Low measurement error
• Strong anti-contamination capability
• Reliable vacuum measurement display
• Suitable for low vacuum measurement and control
• Red and green indicator light alarm output
• Integrated RS232 communication interface
• Compact panel-mounted design
• Lightweight and convenient for installation
• Especially suitable for refrigeration vacuum applications

Working Principle
The ZDO-54DS Thermocouple Vacuum Gauge uses a thermocouple vacuum sensor to detect changes in gas pressure.
Under different vacuum conditions, the heat transfer characteristics of the gas surrounding the heated sensing element change. These changes affect the temperature of the sensing element and generate corresponding thermoelectric signals. The electronic control unit processes these signals through a digital measurement circuit and converts them into vacuum pressure values displayed in Pa.
This working principle enables the refrigeration vacuum meter to provide continuous monitoring of low vacuum conditions for vacuum measurement and process control.
