RM Series Gas Monitoring
If you need to perform gas detection at only one point, or have several points that are either widely separated, or would each be better served by a self-contained monitoring system, check out Interscan’s LD or RM Series. These tough, field-proven units are available for Br2, CO, Cl2, ClO2, C2H4, ethylene oxide, HCHO, H2, hydrazine, HBr, HCl, HCN, H2O2, H2S, NO, NO2, O3, peracetic acid, propylene oxide, and SO2

Interscan’s Rack-Mount configured gas analyzers are intended for those applications in which line power operation is desired (allowing continuous operation and the incorporation of heavier-duty alarm signals or alarm contacts), but in which the rigorous NEMA 4X packaging of the LD Series is not required.
Designed to be installed in a standard 19 inch (483 mm) rack or to be used on the bench, their open frame construction and use of standard electrical and pneumatic components allow easy incorporation of the units into a system. Many of the LD Series’ features and options are available.

Specifications
Accuracy |
Analog units: ±2.0% of full scale
Digital units: ±2.0% of reading, ±1 least significant digit
(Limited to accuracy of calibration standard) |
Repeatability |
±0.5% of full scale |
Minimum Detectability |
1.0% of full scale
[Better on certain digital models]
Note that any data obtained at the level of minimum detectability will not be accurate. |
Linearity |
±1.0% of full scale |
Zero Drift |
±1.0% of full scale |
Span Drift |
Less than ±2.0% of full scale (24 hours)
The zero and span drift specifications assume that the analyzer is equilibrated, and is at constant temperature, with a properly maintained sensor.
“Drift” is defined as an undesired change in output over a period of time, which change is unrelated to input, operating conditions, or load. |
Lag Time |
Less than 1 second |
Calibration |
Against standard gas mixture, or via INTERSCAN’s Electronic Calibration Service |
Compliance with EC Directives on RoHS and WEEE |
Compliant. Refer to detailed information. |
Operating temperature range |
4000 Series: 32°-120° F (0-48.9° C) ¦ LD and Multipoint models can be outfitted with thermostatic enclosures. |
