Leaders in Pressure, Vacuum and Gas Flow Measurement and Control

For over 25 years, Chell has applied skills to the accurate measurement and control of process and test conditions for applications from scientific experiments right through to industrial process control. Many current control techniques have been prototyped in our laboratory and we continue to develop new control methods as the number of available sensors and control elements expands.

Our range of experience, products and services is very wide and we bring the skill to design and manufacture custom test, calibration and production systems. In many cases our techniques involve the combination of control of one parameter and tracking of its effect on another. For this reason, we list below the dynamic ranges of the instrument systems we handle.

VACUUM:	10^-6 mb to Atmosphere
ABSOLUTE PRESSURE:	10^-6 mb to 500 lbf/in²
DIFFERENTIAL PRESSURE:	0.001 mb to 6800 mb
GAUGE PRESSURE:	1 lbf/in² to 750 lbf/in²
GAS FLOW:	0.1 cm³/min to 15,000 litre/min

All these measurements are made with the best available uncertainties for calibration laboratory or industrial process monitoring or control.
