INTEGRATED EMISSIONS ANALYZER
(ENGINE EXHAUST)

Use it to check engine emissions of CO, HC and CO2 by BAR 97 certified NDIR measurements. Optional NO measurement and spark-detection sensor.
Sampling system: Teflon/Viton tubing and water trap or thermoelectric cooler.

M500
This low-cost micro-emissions monitoring system utilizing large electrode-area, filtered electro-chemical sensors. It is designed to help you meet the challenges of a rapidly changing regulatory environment. It is easy to use, comprehensive (NO-NO2-SO2-CO-O2-Comb) and flexible.The measurement of a comprehensive range of automatic emissions calculations (Grams/Brake Horsepower Hour, Pound/Million BTU), advanced Trademark Windows® software, two-way communications, and factory support. From low NOX burners (0.1 ppm NOX resolution) to
Large rich-burn engines (5000 ppm NOX/20,000 ppm CO) all this at an affordable price. 
M700
SEM™ STACK EMISSIONS ANALYZERUses superior TRUE emissions SEM™ sensors to monitor all relevant emissions from stacks
including CO, NO, NO2, & SO2. Equipped with two pumps for sampling and purging. Dilution System increases measurement ranges four-fold.
Sampling system: Teflon/Viton tubing and thermoelectric cooler or advanced Permeation drier.SEM™ INTEGRATED EMISSIONS ANALYZERMulti-purpose, top-of-the-line emissions analyzer for ALL types of measurements. Features SEM™
CO, NO, NO2 and SO2 dual-range sensors and NDIR CO, HC and CO2 sensors.
Equipped with two pumps for sampling and purging.
Sampling system: Teflon/Viton tubing and Thermoelectric cooler or advanced Permeation drier with optional Velocity probe attachment for mass emissions measurement.Not all electrochemical sensors are the same.Normal temperature variations can overstate your emissions. When the test box temperature
was raised from 700F to 970F, the standard electrochemical sensor erroneously reported a
concentration of 47 PPM of NO gas when no gas was present. This change is the result of
the interaction between temperature and a sensor’s history of exposure. The SEM sensor is
temperature controlled per EPA’s CTM-022 Sec.7.2.1. (Electronic manipulation of a sensor’s
output would understate emissions and is “unacceptable” per CTM-022 Sec.2.3.1.)Comparison of the standard electrochemical sensor vs SEM sensor performance as the ambient
temperature is increased. Testing Procedure: After each sensor was exposed to 1000 PPM NO gas
for ten minutes, the gas was removed, and both sensors were allowed to return to zero. The
temperature was then raised from 700F to 970F.
