The IDT SGAS701 is a solid–state chemiresistor sensor designed to detect hydrogen in air. The sensor uses an integrated heater with highly sensitive MOx material tailored for detection of hydrogen.
Applications
Leak Detection
Gas Concentration Detection
Breath Detection
Features
High sensitivity to low hydrogen concentrations (<10 to 1000 ppm)
Fast response time (<15 seconds at 100ppm)
Environmental humidity range of 0% to 90% RH,
non-condensing
Low dependence on flow rate
Rugged, reliable sensor based on IDT’s exclusive technology
