IMR Environmental Equipment, Inc.




Gas analyzer for the continuous and simultaneous measurement of O2, CO (H2 compensated), SO2, NO, NO2, H2S, air temperature, flue gas temperature, pressure/ draft and soot.
Calculated variables are CO2, Lambda (excess air) and qA (losses). 
Simultaneous display of all measuring variables on the monitor. The thermal printer allows the documentation of the measured variables. 
The following printouts are standard: measurement, average values, line graphics.
All printouts with date, time and selected fuel. The printer is suitable for graphics and can be used as Multi Channel Line Recorder. 
Memory for 10485 measurements. 
Operating instructions are clearly displayed on the monitor and the instrument is easy to handle.Values, e.g. fuel parameters are programmable by the user. A special self check program monitors all functions. Error messages or a request for service are displayed on the monitor. 
Option: 8-channel analog output terminal (0-10 V, 4-20 mA) or video output terminal.

Display :
5" CRT for the simultaneous display of all measured parameters. 
Languages: German, English, French  Operating instructions are clearly displayed. 
Units either in ppm, mg/Nm³ or mg/Nm³(O2).
Printer :
Thermal printer with graphics capability. The following printouts are available: measurement, average values, line-graphics. 
The time intervals between printouts can be selected between 1 and 99 minutes.
Printing paper :
Thermal paper, paper width 80 mm, paper length about 30 m.
Multi Channel Line Recorder : 
The printer can be used as Multi Channel Line Recorder. Up to three channels can be shown at one time. Channels are selectable. All values which are stored can be printed. It is possible to record all parameters and select up to three lines for printing.
Memory :
For all measuring variables, for 10485 measurements. The sampling rate can be varied between 1 and 255 seconds. The stored values can be printout as line-graphs or can be transferred via the serial interface (RS 232 C).
Interface :
RS 232 C or optional RS 422
