No drift over 30mbar absolute, even in the extreme vacuum
Ceramic sensor ensure exceptionally reliable measurements even in distillation columns operating at extreme vacuum levels
Cerabar PMC71B reliably measures vacuum pressure, which helps to enhance process yields and results in more consistent product quality.
Results
Accurate measurement
Optimized operation
Maintenance made easy
Challenge
