ZDJ digital resistance vacuum gauge this instrument uses the principle of heat conduction in vacuum related to vacuum degree to measure vacuum. The 16 bit high-speed data acquisition system of American company and high stability microprocessor are used to monitor the new circuit, which is suitable for 1.0e5-5.0e-2pa Zj-52 metal resistance gauge (called Pirani gauge in foreign countries) is widely used in mechanical pump test, chemical raw material vacuum blending, vacuum smelting, vacuum impregnation, air conditioning and refrigerator production line and other industrial and scientific research departments.
