- General Details
H2scan’s HY-OPTIMA™ 1720 in-line, real-time hydrogen specific process analyzers are designed for ease of use, interface flexibility and process control. The HY-OPTIMA™ 1720 is an intrinsically safe, solid-state sensor that is configured to operate in air background gas streams with up to 95% relative humidity and temperatures up to 60ºC. It is ideal for the detection of hydrogen within processes where real-time monitoring can increase plant safety, improve process diagnostics and enhance maintenance management.
