1.2 Features

• Analysis Ranges: The PEM-9004 is available with the

following analysis ranges:

• O

0-20.9%

• CO 0-4000 ppm

(with H

compensation)

• CO

(calculated from O

measurement)

0-CO

max (fuel specific)

And optionally:

• CO 0-2% (0-20,000 ppm)

(without H

compensation)

• NO 0-2000 ppm (optional)

• SO

0-2000 ppm (optional)

• NO

0-200 ppm

• CO Sensor Protection: The PEM-9004 incorporates a special

CO sensor protection feature utilizing a separate pump that

automatically flushes the CO sensor when an upper CO

threshold of 4000 ppm is exceeded.

• Pressure/Draft Measurement: A piezoresistive pressure

sensor with internal temperature compensation is installed for

measuring pressure up to ± 60 inches of water (iWC). A

convenient port is located on the front panel for positive or

negative pressure measurements.

• Temperature Measurement: Both ambient and gas

temperatures up to 1850°F (1000°C) are monitored using K-

type (NiCr-Ni) thermocouples. These parameters are used by

the internal processor in calculating combustion efficiency,

waste gas loses, excess air and undiluted CO concentration.

• Waste Gas Sampling: Via an external water separator and

filter, the waste gas is fed to the sensors by means of a gas

feed pump. It accepts either a one point measurement probe

(combi-probe) or multi-point measurement probe (multi-hole

probe).
