VR-208Series intelligent vacuum gaugeIt is a new type of thin film vacuum gauge with intelligent measurement and control functions. It is a universal vacuum degree display and adjustment instrument used for industrial automatic measurement and control of vacuum equipment, such as biomedicine, vacuum freeze-drying, pharmaceuticals and fine chemicals, medical vacuum cold chain technology, vacuum acquisition equipment, multi-stage vacuum units, vacuum drying, vacuum coating, vacuum metallurgical heat treatment, vacuum single crystal furnace, vacuum equipment, chemical vacuum distillation, electrical insulation vacuum impregnation equipment, vacuum infusion, vacuum oil filter, vacuum pre cooling preservation, vacuum food processing equipment, vacuum environmental protection filtration, purification system, etc. It is also used in laboratories, measuring rooms, etc（0.01Pa—100kPaof0.5—0.1A vacuum degree standard with high precision.

VR208The series of intelligent vacuum meters adopts the new generation of capacitance film vacuum measurement technology (high-precision ceramic capacitance film gauge, etc.) from abroad as the vacuum degree sensor. It integrates the research results of intelligent instrument technology and overcomes the limitations of traditional vacuum meters (thermocouple meter, resistance meter, Pirani gauge and other thermal conductivity vacuum meters)pvcDefects such as the need for calibration, large measurement errors, and large drift in alloy thin film meters, Maxwell meters, etc. before measurement, and the annual stability of ceramic capacitors<0.1%Used for industrial control without calibration within the year）The online continuous measurement of vacuum degree by the instrument significantly improves the metrological stability and the reliability and safety of process control;

The thin film vacuum gauge is a vacuum degree measuring instrument that can be used as a secondary standard for low vacuum measurement work and is currently a vacuum degree measuring instrument in the metrological calibration and verification regulations. In addition, the capacitive thin film vacuum gauge is a vacuum gauge that measures absolute and total pressure, and its measurement results directly reflect the change in vacuum pressure, which is only related to pressure and not to gas composition. The VR-208 series intelligent vacuum gauge combines the performance of ceramic capacitive thin film vacuum gauge and intelligent measurement and control instrument, and is the choice for upgrading traditional vacuum gauges. It is a precision vacuum measurement and control instrumentchoice.
