Thermocouple Vacuum Controller
Hot Cathode Ionization Vacuum Meter
Type: ZDR-10B
Thermocouple Vacuum Controller:
ZDR-10B ionization vacuum gauge can test one circuit vacuum gauge sign and has two circuits control contact output. In the testing range, it can be point control and area control freely. It is suitable to be used in testing and controlling the vacuum of wide measuring range.
It adopts the most advanced microprocessor as its main machine, improving its reliability by decreasing external components. Its hardware employs the modular structure, EMI restraint and WATCHDOG circuit; while the software employs anti-interference technique, such as redundancy, trap, digital filtering and so on to improve its anti-interference ability and performance, which ensures the high reliability of the apparatus and its normal use in bad industrial environment.
