Portable Fuel Gas Analyzer 940

  • Long life zirconium sensor
  • Very fast response, no purgetime
  • No reference gas required
  • High accuracy
  • Wide measurement range 1 ppm to 96%
  • Simpletooperate
  • Maintenance free
  • automatic & begins with every start up with fresh air aspirated instead of Gas sample..
  • Automatic self check for efficiency calculation :With aspirated fresh air specific percentage efficiency of the selertpd Fuel is displayed as a cherk nn its calculations.
  • Self Supervisory Diagnosis : Continuously checks the status of: 1) Battery Voltage 2) Sample Flow 3) Oxygen Sensor
  • Sturdy stainless steel sampling probe with extension tubing for ease of measurement.
  • Thermocouple in the tip of probe measures temperature at point of sampling to minimise error.
  • Time tested high suction inbuilt sampling pump acts against draft. Supervisory circuit continuously monitors it against failure.
  • Inline Filter to Inbuilt Moisture & Dust, Disposable easy to replace filter element. Supervisory Diagnostic circuit continuously checks it against choking.
  • Retains the readings till the next sampling.
  • Compact Aluminum Housing
  • Rechargeable Ni-cad battery pack with charger.
  • Maintenance & Spare Parts : Designed for free maintenance operation. Long Life Sensor.
  • Combustion efficiency is determined by Oxygen content and temperature of Fuel gases. An excess air (Oxygen) condition reduces the efficiency as it carries away the heat while a deficient air (Oxygen) produces an incomplete i combustion with consequent higher costs and increased polluting emissions.
