Integrated thermal conductivity sampling system
The SGS™ – Single-Gas Sensor measures hydrogen content with high accuracy in binary or quasi-binary process atmospheres. The SGS™ is low maintenance and boasts a long service life which eliminates the need for heated sample lines, filters, etc. The SGS™ can be stand-alone or integrated into a new or existing control system.
Ideal for measuring hydrogen content or dissociation level with high accuracy in nitriding and nitrocarburizing atmospheres, the SGS™ is also capable of calculating KN and KC for controlled nitriding and nitrocarburizing.
The integral sampling system eliminates the need for a separate external system. This one-piece SGS™ sensor is mounted directly on the process exhaust line or a sample port and uses the Venturi effect to sample the atmosphere.
