Alphatech is delighted to have supplied Chell Instruments with a new generation Aralab Testa chamber as part of their ATEX chamber project.

Chell has been a supplier and manufacturer of quality pressure and flow instrumentation for more than 40 years.

The project included incorporating a number of safety features to allow gas meter devices to be operated using the gases that they are designed to carry, now and in the future. Within this chamber, units can be tested using air, nitrogen, hydrogen or methane, all at temperatures ranging from -30°C to +70°C and flow rates from 20sccm (0.0012 m3/hr) to 480 slpm (28.8 m3/hr).

Working closely with Aralab along with our other suppliers allows us to find solutions to our customers’ bespoke requirements. Please get in touch with your enquiries at We welcome your innovation and ambition.
