Capacitance meter CMC

Compact, proven unheated gauges for cost-effective vacuum measurement.

CMC Series capacitance manometers from Brooks Instrument deliver reliable, accurate vacuum measurement over a wide range of operating temperatures, providing an economical alternative to larger premium unheated gauges. Its compact design and proven performance make it an ideal upgrade for existing tools needing a small form-factor gauge.

Reliable and repeatable operation is assured in even the most aggressive processes through the all-welded design and Iconel® wetted surfaces. The combination of precision components and a wide temperature compensated operating range lets Brooks deliver best-in-class zero and span temperature coefficients for optimum measurement stability.

Features
• Available for process ranges from 10 Torr to 1000 Torr
• Two accuracy levels available: 0.25% or 0.50% of reading (optional)
• Exceptional performance over a wide range of operating temperatures
• 40% smaller than traditional unheated capacitance manometers
• All-welded construction and Inconel® wetted surfaces

Benefits
• Optional high accuracy calibration matches the accuracy of more costly premium unheated manometers
• Best-in-class zero and span temperature coefficients
• Space-saving design helps fit device into tight machine spaces
• Optimum measurement repeatability compared to other designs that are prone to error inducing internal stresses
