NEO987M

H2 sensor measurement up to 100%.

« all products NEO987M

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) or TCP (Ethernet) under extreme conditions.

Typical applications are e.g. the determination of hydrogen concentrations under inert conditions or the use in the anode circuit of PEM fuel cells to determine a tertiary mixture of hydrogen, nitrogen and water vapour

Most important features:

  • Measuring range H2: 0-100 vol.% in N2 /O2 -N2 mixture
  • Temperature measuring range: -40 - 120 °C
  • Pressure range: up to 10 bar absolute
  • Humidity: 0-100 % r.h. (non-condensing)
  • Response time: t90 < 5 s
  • Recovery time: t10 < 5 s
  • Signal output via RS485 (Modbus RTU) or Ethernet with Modbus-TCP protocol 
  • Gas adapter available as screw-in version or for measuring gas in a tube
