The SAM-I MAX and SAM-IV MAX Specific Air Monitors are continuous monitoring systems that use infrared technology to measure the concentration levels of organic compounds in ambient air, including HCFCs, HCCs, HFCs, and other refrigerants. The monitor's unique optical design allows it to be compound specific (virtually no false alarms). Concentration is measured in parts per million (ppm) from 1 ppm to 1,000 ppm and indicated on the monitor's front panel liquid crystal display (LCD).
A SAM-I MAX Monitor can monitor one sample point unless an expansion module is added. If an expansion module is used (four point or eight point), the monitor's front panel LCD continually displays the last concentration level sampled from each sample point. The SAM-IV MAX offers four ports unless the optional expansion modules are used (four or eight ports). This expands the SAM-IV MAX to seven or 11 ports. On the LCD, an arrow appears next to the sample point currently being sampled.
Features:
· Single or multiple point refrigerant monitoring.
· Customized to monitor any refrigerant including HCFC-123, HFC-134a, HCFC-22, CFC-11, CFC-12, carbon monoxide, or ammonia.
· Capable of monitoring combinations of up to three refrigerants. Each port can be calibrated for a different refrigerant.
· Complete digital control of instrument parameters through RS-422, RS-485 or optional RS-232 interface.
· Optional Windows®-based software for monitoring gas levels and controlling instrument settings remotely.
· Factory calibrated - No calibration required on start-up or for the first year.
· Modular design allows service and calibration without removing the system from the wall.
· Three adjustable alarm levels with a relay closure for each alarm level that can be used to actuate external alarm lights, horns, or emergency ventilation systems.
· Detects leaks as low as 1 ppm-no humidity calibration required.
· A transparent window on the front door of the NEMA IV cabinet is provided to allow the operator to view the display without compromising system stability.
· SAM-I MAX Monitor meets ASHRAE-15 1994 and USEPA 608 monitoring standards.
