Thermoelectric Chiller 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 chiller is designed for superior sample conditioning and can handle flue gases up to 40% water content.

Auto Condensate Drain The built-in condensate drain pump automatically pumps the accumulated water out through the bottom of the unit for greater convenience, especially when used in long term testing and monitoring.

Wireless Remote Printer 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 chiller is designed for superior sample conditioning and can handle flue gases up to 40% water content. The E8500 has an optional wireless remote thermal printer for convenient, simple, and easy use to print real-time in the field or at a later time for saved tests and data.

Internal Data Memory An extensive internal memory (up to 1000 tests) allows for data storage of all measured & calculated parameters. The memory can also be utilized for programmable longer term data storage.

Real-Time Software The standard “EGAS” software package includes the ability to save & 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 is done via Bluetooth wireless communications. A Bluetooth module for a PC 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 emissions reports.

Gas Sensors The E8500 can have a maximum of nine total gas sensors, up to six electrochemical type sensors and up to three NDIR type sensors. The chart below details each sensor.

Temperature Measurements Temperature measurements for the flue gas and air as well as the differential temperature are standard features. The differential temperature is used as part of the efficiency calculation.

Draft, Pressure, & Velocity An internal pressure sensor allows the analyzer to measure pressure and stack draft. With two pressure inputs, a 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 back light and can be rotated for greater ease and convenience. The parameters displayed can be zoomed in to view from a distance or zoomed out for more parameters at once on the display screen.

Calibration 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.
