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.

LD Series   Click Here for Larger View Interscan's LD Series represents the ultimate in single point continuous gas monitoring systems. Each and every component has been chosen based on years of experience in some of the most demanding environments imaginable. What's more, the units are easy and inexpensive to maintain. An impressive array of options allows the specifier to put together a system ideally suited to the application at hand.     Options Alternative packaging, including Type X or Type Z purged enclosures and RFI resistant enclosures Audible alarm Visual alarm Enclosure heating and cooling Loss of flow alarm Triple alarm set points Loss of power alarm Aspirator (in lieu of pump) Auto zero Sensor protection circuit   Features Super-rugged NEMA Type 4X fiberglass reinforced polyester enclosure 3½ digit LED display Integral diaphragm pump Rotameter Analog output---   0-1 V & 4-20 mA full scale Low and high alarm contacts, continuously adjustable through the full scale measuring range, activating dedicated relays Additional Specs Resolution 0-2000 ppm range 1 ppm 0-1000 ppm range 1 ppm 0-500 ppm range 1 ppm 0-200.0 ppm range 0.1 ppm 0-100.0 ppm range 0.1 ppm 0-50.0 ppm range 0.1 ppm 0-20.0 ppm range 0.1 ppm 0-5.00 ppm range 0.01 ppm 0-2.00 ppm range 0.01 ppm 0-1.00 ppm range 0.01 ppm Weight: 22 lb (10.0 kg) Dimensions: 22" H x 18" W x 8.5" D (559 x 457x 216 mm) Specifications common to all Interscan gas detection instruments

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.   Options Integral pump Rotameter Loss of flow alarm 4-20 mA analog output Alarm contacts Dual alarm set points Triple alarm set points Loss of power alarm Slide rail hardware and access door, for rack mounting     Features 3½ digit LED display Wrap-around cover 0-1 V analog output Additional Specs Resolution 0-2000 ppm range 1 ppm 0-1000 ppm range 1 ppm 0-500 ppm range 1 ppm 0-200.0 ppm range 0.1 ppm 0-100.0 ppm range 0.1 ppm 0-50.0 ppm range 0.1 ppm 0-20.0 ppm range 0.1 ppm 0-5.00 ppm range 0.01 ppm 0-2.00 ppm range 0.01 ppm 0-1.00 ppm range 0.01 ppm Weight: 8 lb (3.6 kg) Dimensions: 7" H x 19" W x 12" D (178 x 483 x 305 mm) Specifications common to all Interscan gas detection instruments

  † 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.
