Alarms

High and/or low alarm contacts available, relay contacts SPDT 5A @ 220 VAC rating

Analyzer Type

H2 Analyzer

Hazardous Area Rating Options

General Purpose, Non-Hazardous


Applications
    For continuous analysis of up to 100% hydrogen (H2) in process gas streams. Also recommended for other applications such as H2 cooled generators, electrolysis units, refinery gas, heat treating atmospheres, blast furnace gas, and many more.

    The Nova 430 Series Process Hydrogen analyzer utilizes a temperature-controlled TC cell for the detection of H2 in process gas. This cell produces a small millivoltage output which is directly proportional to the H2detected. This output is then amplified and displayed on a digital readout meter and is also available as an output recorder. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement.




Features
  • Best value continuous H2 analyzer
  • Bright digital readout, 4-20 mA outputs
  • Long life thermal conductivity (TC) detector with high accuracy and repeatability, cannot be burned out from loss of flow
  • Fast response (T90 - 10 to 15 seconds)
  • Easy-to-maintain modular layout
  • Built in sample pump or pressure regulator
  • Sensor mounted in temperature controlled heated box to improve accuracy




Options
  • Hi/Low gas, low flow, and diagnostic alarms available
  • Isolated analog, RS232, RS485, MODBUS, and Ethernet outputs available
  • Sample conditioning systems available for removal of moisture, acidic gas, and dust
  • Cabinet purge system available for use in hazardous areas
  • One-step 'cal-now' button with touch screen LCD display
  • Full automatic calibration with touch screen LCD display
  • Cold weather package for operation to -5°F (-20°C)
  • Cabinet coolers can be fitted to most models
  • High temperature filters and probes




Calibration
  • Nitrogen or air for zero
  • Span using a known H2 in nitrogen calibration gas.
