CY-ZJ-54D Thermocouple Gauge

This type of gauge tube uses stabilized nickel-chromium-constantan as heating and thermocouple wires. It features automatic ambient temperature compensation and dust protection, offering simple structure, wide measurement range, fast response, pollution resistance, oxidation resistance, low drift, long life, stable performance, and moderate price. It is particularly suitable for low vacuum measurement. This gauge tube can be interchangeably used with the ZJ-53 glass thermocouple gauge tube.
