H2SMART

INTELLIGENT HYDROGEN SAMPLING SYSTEM FOR NITRIDING & NITROCARBURIZING

he H2Smart™ measures Hydrogen content with high accuracy in process atmospheres. It features an integrated sampling system with flow control which assures reliable sampling and measurement. The H2Smart™ can be used stand alone or integrated into a new or existing control system.

H2Smart™ is available in 3 models:

  • Base model for % H2 measurement
  • LT model includes base capabilities plus simplified KN calculation
  • PRO model includes LT capabilities plus extended calculation of pH2, pNH3, pO2, pCO, pCO2, KN, KC, KO and dissociation
