NEO983M

Hydrogen measuring system in oxygen-free and oxygen-depleted air with temperature, pressure and humidity compensated signal evaluation and output via Modbus RS485 (Modbus RTU). 

Typical applications are e.g. the detection of hydrogen in fuel cell exhaust gas and the determination of hydrogen concentrations in oxygen-depleted air.

Most important features:

• Measuring range H₂: 0 to 10 vol% H₂
• Temperature measuring range: -40 - 85 °C
• Pressure range: 0.6 to 5 bar absolute
• Humidity: 0-100 % r.h. (non-condensing)
• Response time: t₉₀ < 3 s
• Recovery time: t₁₀ < 3 s
• Signal: Signal output via RS485 (Modbus RTU) protocol
• Gas adapter available as screw-in version or for measuring gas in a tube
