The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Varian - Model: 0531 - Condition: Used and in Excellent Condition - Price: $195.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 1 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Lab & Analytical > Other Lab (primary) ## Function Component containing thermocouple junctions housed in a sealed tube that converts gas-induced cooling of a heated element into a low-millivolt signal, used to determine vacuum pressure in rough to high-vacuum systems. The device heats a resistance element and senses the resulting temperature differential with a reference junction, producing a millivolt output proportional to vacuum pressure. It requires cold junction compensation and is designed for integration with vacuum gauges and controllers, providing electrical readout and control signals for the vacuum system. ## Images - - - -
