Infrared Four Gas Monitors | SAM IV Model

Supplier: Control Equipment

SAM IV continuous refrigerant monitors use patented infrared technology to detect refrigerant gases as low as 1ppm. The SAM IV’s unique optical design allows it to be compound-specific, which practically eliminates nuisance alarms from other compounds that may be present.

The SAM IV incorporates the monitor and sample manifold in one compact, watertight package. One instrument can monitor up to 11 sample points with optional expansion module packages. Samples can be collected from distances of up to 500 ft. SAM IV monitors are less sensitive to vibration and temperature fluctuation than most units and can be mounted on the wall, rack or the refrigeration or HVAC
equipment itself. Three level alarms warn against refrigerant leaks. Standard outputs include 4-20 mA and a choice of RS-485 or RS-232. Optional Windows-based software is available for remote control of all parameters of the SAM IV monitors.
