SGS™

SINGLE-GAS SENSOR FOR NITRIDING & NITROCARBURIZING

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™ has a low-maintenance requirement and long service life, and eliminates the need for heated sample lines, filters, etc. The SGS™ can be used 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 to the process exhaust line or to a sample port and uses the Venturi effect to sample the atmosphere.
