APPLICATIONGENERAL DESCRIPTIONThe SUPERIOR™ Model SLD-2 Dual Channel Gas Detector isa state-of-the-art, microprocessor controlled instrument
capable of detecting Chlorine, Sulfur Dioxide, Ammonia, andOzone gasses at levels far below the threshold of humanawareness. SUPERIOR™ Dual Point Gas Detectors are an“operator friendly” and economical way to protect personneland property. The detector will individually monitor any twolisted gas levels, or two separate locations of the same gas,
well below OSHA requirements, and activate warning devices
when threshold levels are reached.
The Model SLD-2 Dual Channel Gas Detector consists of aController/Alarm module, and two remote gas
sensor modules which can each be located up to1000 feet (305 meters) away from the controller.
The sensors respond immediately to thepresence of gas, and recover very quickly
when the gas has cleared.
Thecontroller/alarm module is housed in a NEMA4X enclosure. Many features which are extra
cost options in other gas detectors, are standard
with the SLD-2.

FEATURESThe SUPERIOR™ Model SLD-2 is designed for use in:! Wastewater treatment plants! Water purification plants! Swimming pools! Cooling towers - air scrubbers! Food and beverage processing! Chemical processing
SUPERIOR™ design provides ease of operation with topperformance. The SUPERIOR™ Series SLD-2 Dual Channel
Gas Detector can be placed where most convenient for theoperator for ease of use while the gas sensor can be placedin the monitored environment up to 1000 feet (305 meters)away.
Materials used in manufacturing the SUPERIOR™ Series SLD2 Dual Channel Gas Detectors have been carefully selected
for their superior quality and performance insituations and conditions far more extreme
than conditions to be encountered in actualuse.

AVAILABLE OPTIONS• Internal Battery backup with charger.
An external UPS may also be used toallow full function operation overextended power outages.
• RS232 serial port for downloadingdata.

• User-friendly key pad interface with functions
indicated by individual menu display screens.
