  • Complies with US-EPA CTM-030 & CTM-034 test methods

Thermoelectric Chiller with Auto Condensate Drain

The internal thermoelectric chiller efficiently and quickly removes the water vapor from the flue gas sample to prevent combustion gases from bubbling from the gas phase into the condensate. The built-in condensate drain pump automatically pumps the accumulated water out through the bottom of the unit for greater convenience.

Real-Time Software

The standard "EGAS" software package includes the ability to save and graph data in real-time in the field with a laptop or in a laboratory with a PC. Communications between the E8500 and a computer are done via wireless Bluetooth communications or a USB cable. A Bluetooth module for a computer comes standard with each E8500 gas analyzer. Data from the "EGAS" software can be exported to other spreadsheet programs for more user flexibility to create detailed emissions reports.

Sensor Options

Measures up to 9 Gases of your choice (up to 6 electrochemical type, and up to 3 NDIR type):

  • O2:  0-25%, Electrochemical
  • CO: 0-8000ppm, Electrochemical
  • CO Auto range: 0-20,000ppm, Electrochemical
  • CO: 0-15% NDIR
  • NO/NOx: 0-5,000ppm Electrochemical
  • NO2: 0-1000ppm Electrochemical
  • Low NO (and/or Low NO2): 0-500ppm Electrochemical
  • NOx: 0-5000ppm Calculated
  • SO2: 0-5000ppm Electrochemical
  • CO2: 0-99.9% Calculated
  • CO2: 0-50% NDIR
  • CxHy: 0-3.00% NDIR
  • H2S: 0-500ppm Electrochemical 

Draft, Pressure, & Velocity

An internal pressure sensor allows the analyzer to measure pressure and stack draft. With two pressure inputs, differential pressure can also be measured. Gas velocity can be measured using the differential pressure and an optional Pitot tube.

Rotating Display with Zoom

The LCD display screen has a continuous back light and is automatically rotated. The parameters displayed can be zoomed in to view from a distance or zoomed out for more parameters at one on the display screen.


The analyzer comes standard with a complete factory calibration. The analyzer can easily be recalibrated with span gas cylinders. Recalibration is recommended at least once each year to ensure analyzer accuracy.

Weight: 11lbs (5kg). Dimensions: 10x6x9.5" (26x15x24cm)
