The controller and Duniway thermocouple sensor appear to be in good overall cosmetic condition. Calibration status and measurement accuracy have not been independently verified. Please review the photographs carefully for the exact condition, meter face, controls, connections, sensor, cable, labels, and included components.DescriptionVarian 531 TC analog thermocouple vacuum gauge controller supplied with a Duniway DST-531 thermocouple vacuum gauge sensor.This system is designed for rough-vacuum pressure measurement in compatible laboratory, industrial, research, semiconductor, coating, deposition, pumping, and vacuum-chamber applications. The analog controller displays pressure in millitorr or microns and operates from 110V AC power.The included Duniway DST-531 is a Type 531 thermocouple sensor with a nickel-plated mild-steel body and 1/8-inch male NPT process connection. Duniway identifies the DST-531 as equivalent to the Varian F0472301 and Hastings DV-531 sensors.Thermocouple vacuum gauges measure pressure by monitoring heat loss from an electrically heated sensing element as gas density changes. They are commonly used for rough-vacuum monitoring, pump-down verification, vacuum-system troubleshooting, and process equipment.Buyers should verify the controller power requirements, sensor compatibility, vacuum-port connection, calibration needs, and required operating range before purchasing.Key FeaturesGenuine Varian analog vacuum gauge controllerIncludes Duniway DST-531 thermocouple sensorType 531 thermocouple gauge configurationMeasures rough-vacuum total pressureAnalog millitorr / micron meter displayApproximately 1 mTorr to 2 Torr primary measurement rangeFast sensor response to pressure changesSensor may be mounted in any orientationNickel-plated mild-steel sensor body1/8-inch male NPT vacuum connectionDST-531 replaces Varian F0472301 and Hastings DV-531110V AC controller inputSuitable for laboratory and industrial vacuum systemsLightly used with light cosmetic marksIncludedOne Varian 531 TC thermocouple vacuum gauge controllerOne Duniway DST-531 thermocouple vacuum gauge sensorInterconnection cable only if shown in the photographsOnly the items pictured are includedNo vacuum pump, fittings, adapters, calibration certificate, manuals, or additional accessories are included unless shown Shipping Returns Policies Shipping Orders ship within 1 business day of payment, subject to freight scheduling.
