The Chillgard LS Photoacoustic Infrared Refrigerant Monitor provides economical, low-level monitoring. Available in both single-point diffusion and 4-point pumped models, the monitor complies with ANSI/ASHRAE 15-1994. Featuring high performance, sensitivity and stability, the Chillgard LS Refrigerant Monitor can detect the five most common refrigerants (R11, R12, R22, R123 and R134A). The monitor can work either on a stand-alone basis or in conjunction with the Chillgard LC Control Module. With optional plug and play optical benches available, the Chillgard LS Refrigerant Monitor can easily be configured to detect a different refrigerant at a later date.

The MSA Chillgard LC Control Module works with the Chillgard LS gas sensor modules to provide remote signaling and control capability in refrigerant monitoring applications. The Chillgard LS Monitor and LC Control Module combination meets ASHRAE requirements for entryway signaling and refrigeration monitoring. The Chillgard LC Control Module can communicate with up to eight sample points from the Chillgard LS Refrigerant Monitor over an RS-485 communication line.

The Chillgard LE Monitor combines all of the benefits of the Chillgard LS Monitor and Chillgard LC Monitor in one enclosure. The Chillgard LE Refrigerant Monitor can be purchased as either a single-point diffusion unit (no internal pump), single-point pumped unit (for monitoring from a remote location) or a four-point pumped unit.
