COSA 707 Emissions Analyzer

COSA 707

The COSA 707 is a hand held multigas analyzer for industrial and combustion processes.

The COSA 707 is an easy to hold, hand-held emissions analyzers capable of measuring up to seven different gases.

The emissions analyzer can be equipped with up to 6 electrochemical sensors and a CO2 IR-bench for simultaneous measurements. Cells can be installed for making measurements of low CO and low NO down to 0.1ppm.

The COSA 707 has a bright  3.5" TFT display with backlights and a zoom function. The unit can communicate through Bluetooth, USB or with a 2GB SD-Card.

New sensors for the COSA 707 include a CO2 sensor for a range of 0-20% (IR-Bench) and a H2S sensor for 0-500ppm (EC Sensor).

The 707 can make the following measurements:

O2 0 - 21%
CO2 (IR bench) 0 - 20%
CO2 (calculated value) 0 - 20%
CO low 0 - 300 ppm
CO/H2 Compensated 0 - 10,000 ppm
NO low 0 - 300 ppm
NO 0 - 5,000 ppm
NO2 0 - 1,000 ppm
NOx 0 - 5,000 ppm
SO2 0 - 5,000 ppm
H2S 0 - 500 ppm
CO high 0 - 2%
CO very high 0 - 10%
Combustion Air Temp. up to 100'C
Stack Gas Temp. up to 1,100'C *
Stack Draft Measurement +/- 100 hPa
Differential Pressure +/- 100 hPa
Differential Temp.

up to1,100'C *

* with adequate probe

The 707 can also make the following calculations:

Carbon Dioxide (CO2) 0 - 20%
Heat Losses (qA) 0 - 99.9%
Efficiency 0 - 120%
Air Ratio 1 - 9.99%
Excess Air 0 - 99.9%
