ZDZ-4JA Pirani Vacuum Gauge

Product Introduction
The ZDZ-4JA Pirani Vacuum Gauge is a touchscreen digital vacuum measurement instrument designed for rough and low-vacuum applications. Powered by a Cortex3-core processor, it delivers fast response, high reliability, a wide measurement range, and good repeatability. Its compact design, stable performance, and cost-effective operation make it suitable for routine vacuum monitoring in laboratories and industrial environments.

Performance Features
• Touchscreen Operation: An intuitive touchscreen interface simplifies parameter viewing and instrument operation.
• Wide Measurement Range: Measures vacuum pressure from 1×10⁵ Pa to 1×10⁻¹ Pa.
• Fast Response: The Cortex3-core processor supports responsive measurement and efficient operation.
• Reliable Performance: Designed for stable readings and good measurement repeatability.
• Four Pirani Gauge Sensors: Supplied with four CY-1Z resistance vacuum gauges for multi-point vacuum monitoring.
• Compact Design: A small enclosure saves installation space and facilitates integration into vacuum systems.
• Standard KF16 Interface: Simplifies connection to compatible vacuum equipment.

Working Principle
The ZDZ-4JA uses the Pirani thermal conductivity principle to measure vacuum pressure. A heated sensing element loses heat through the surrounding gas, and the rate of heat transfer varies with gas pressure. By detecting changes in the sensing element's thermal characteristics, the instrument converts the signal into a corresponding vacuum pressure reading. This method enables continuous monitoring of rough and low-vacuum conditions.
