Vacuum gauge classification
1. Thermocouple gauge
At present, the main domestic thermocouple gauges 51 series, 53B/54D and so on. Mainly used for low vacuum measurement.
2. Pirani Series (Resistance regulator)
At present domestic resistance gauge model is mainly 52T series. Mainly used for coarse and low vacuum measurement.
The PG-500 is used with the watch head
Pg-600 communication digital signal directly connected to the PC
Pg-700 switch can directly set the control point for control
3. Hot cathode regulator
The main models are ZJ-2 series, ZJ-10 series, ZJ-27 series, B-A gauge and so on.
This type of regulator is mainly used for high vacuum measurement.
