The Products Section >Continuous Monitoring - Single Point Applications
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, propylene oxide, and SO2.
-- and use our own patented electrochemical voltametric sensors.

| RM Series |
| |
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. |

† These are the new model numbers. Certain other sources may not reflect this system, while the changeover is occurring. If in doubt, specify the gas and the measuring range desired.
¶ There is not a separate analyzer available for each of these compounds, and the sensor does not respond equally to all hydrazine species. The analyzer must be calibrated with the specific hydrazine compound of interest.
Special ranges available on request—The panel meter can be factory programmed to display any desired full scale range, within the measuring capability of the instrument.
