Endee FEM 940 Flue Gas Analyzer

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.
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,
