Overview

Measurement Ranges

The EGM-4 can be supplied with two different optical benches. One bench is optimized for measurement of CO2 in the ranges of 0-1,000 ppm up to 0-30,000 ppm and another optimized for 0-50,000 or 0-100,000 ppm. For users that want
to recalibrate the gas analyzer to a new level, this can easily be achieved as long as it is within the range for that particular optical bench.

Portability
The EGM-4 is a compact, lightweight (1.9 kg) instrument that is packaged in a rugged aluminum enclosure. It can be supplied with either a 12V lead acid battery (up to 4 hours continuous use) or 12V
NiMH battery (up to 8 hours continuous use) making it an ideal instrument for field applications. For laboratory studies, it can be operated continuously
from mains power using the AC power supply that is included.

Integral Sampling Pump

The EGM-4 features an integral, long life air sampling pump that can be controlled for applications that require both dynamic and static measurements or dynamic measurements, the pump operates at a flow rate of approximately 350 ml/min. Static
measurements are performed by simply disabling the integral pump and injecting a gas stream directly into the gas analyzer for analysis.

Data Storage and Output
Measurements can be recorded manually or
automatically at user selected intervals. Data is safely stored in battery backed RAM and can be later output to a PC in standard ASCII format.
Analog and digital output is available for use with external data loggers or for display, collection and recording from an external PC using the Windows®
software included.

Flexible,Versatile User Interface

The EGM-4 is an extremely powerful and versatile instrument. The following accessories/sensors can be used with the EGM-4 enhancing measurement
capability:
• Humidity sensor
• Soil respiration chamber
• Soil temperature
• PAR
• Temperature/PAR
• Canopy assimilation
• Oxygen
• Steady state porometer
