Agilent Technologies 0531TC 531 TC Vacuum Gauge

Agilent 0531TC 531 TC Vacuum Gauge is a stainless-steel thermocouple gauge tube designed for rough-vacuum measurement, delivering fast, orientation-insensitive readings from about 1 x 10^-3 Torr up to atmospheric pressure when used with compatible gauge controllers. This 531 TC tube is part of Agilent's TC gauge family and is designed for use with Agilent gauge controllers such as the RGC-100, RGC-150 or XGS-600, and it ships with a socket for straightforward integration with vacuum hardware. The thermocouple element senses pressure changes and provides an output suitable for controllers that supply current and read an internal voltmeter, using a 4VCR interface to mate with standard vacuum fittings. Constructed in stainless steel, this replaceable gauge tube fits 531/536 TC gauges and is commonly employed in rough-vacuum applications like laboratory vacuum systems and leak-detection setups. This configuration is known for rapid response to pressure changes and for not being sensitive to mounting orientation, making it a reliable choice for quick, repeatable rough-vacuum measurements.
