HyEVO

Hydrogen Gas Analyzer

High-accuracy, high-resolution hydrogen gas analyzer designed to support the development of the hydrogen supply chain.

Essential for the development of technologies necessary to produce, transport and use hydrogen and hydrogen related materials such as ammonia.

HyEVO can be used for many applications in combination with other measurement devices.

Direct measurement of gases with moisture concentrations up to 35% without removing moisture*¹
High-accuracy, high-resolution hydrogen concentration measurement
Can respond to transient changes in gas concentration
Response time ≦ 1 sec, Output frequency 5Hz
Warm-up time of 3 hours (approx. 1/3 compared to conventional models) *²
Power saving function during standby operation

*¹: Use a dehumidification cooler (optional) when measuring with dehumidification or when measuring gases with a moisture concentration of more than 35%.
*²: Comparison with our conventional product (MSHA-1000)
