The Oxy 1900 delivers innovative alternatives that provide unparalleled flexibility, operational performance, and cost savings.
An innovative heated sample bulkhead, when combined with the fully heated sample compartment, can reduce the need for a gas conditioning system on samples with a dew point of up to 50 ºC/122 ºF while also providing excellent measurement stability; a unique FlowCube sensor that guarantees low flow indication during normal operation; and an integrated pressure compensation system that compensates for sample pressure variation, allowing for tighter process control.
