The ECOM CN is an easy to use, handheld gas analyzer designed for basic
combustion monitoring in a variety of applications.

V E T S

The ECOM CN is fitted with 2-3 gas sensors, measuring O2, CO & NO plus Stack and

Ambient Temperatures, and Stack Pressure and Draft. The CN also calculates CO2,

Efficiency, Losses, Excess Air and Oxygen correction 0-20%.

The instrument is housed in a robust composite case suitable for rugged field use. On-board

data storage for up to 500 separate readings. An IR printer port transmits data to a portable

printer for on-the-spot print-outs. A large LCD displays all measured and calculated

parameters at once, or can be “zoomed” to show only those particular measurements the

operator wants to see. The tactile keypad guides the operator through the various functions

of the analyzer.

The ECOM CN sample conditioning system consists of a high flow pump and radiant gas

cooler with moisture trap. An automatic shut-off activates when the gas cooler filter becomes

saturated. Another unique feature of the CN is an Automatic and Manual CO bypass function

which protects the CO sensor from over exposure.
