MKS 631C Baratron Capacitance Manometer 1000 Torr 133.32 kPa 631C13T8FH USED

The MKS 631C (Part Number 631C13T8FH) is a high-accuracy, 100°C Temperature-Controlled Baratron® Capacitance Manometer. Designed for high-performance vacuum measurement, the 631C series is the industry standard for processes where repeatable, gas-independent absolute pressure measurement is critical.

By heating the sensor to a constant 100°C, this transducer minimizes the condensation of process byproducts inside the gauge, significantly reducing zero drift and extending the sensor's lifespan in "dirty" or "clogging" chemistries. This specific unit features a full-scale range of 1000 Torr (133.32 kPa), providing high-resolution data for atmospheric and sub-atmospheric pressure control in semiconductor, pharmaceutical, and industrial vacuum applications.
