Zero air generator

Casella Monitor has introduced ZeroGen, a cartridge-based zero air generator that removes the need for zero calibration gas cylinders when performing calibration checks on ambient air gas analyser systems.

The cartridges are designed to be easily replaced each year which, says Casella, saves considerable time and expense compared to the use of traditional zero calibration cylinders.

Gary Noakes, product manager, explains: "The ZeroGen scrubs the incoming ambient air and produces a purer true zero gas for calibration without all the complications and mechanics of transporting and installing zero calibration gas cylinders."
