Zero drift is consigned to the past with Crowcon’s latest wall-mounting, fixed infrared gas sampling unit, says the company.
Dubbed Deltagas, it uses pressure modulation in which absorption is measured at different pressures. Response does not deteriorate over time.
There’s an integral sample pump and operator panel, and it can measure CO2, CO, methane and ammonia.
