## MSA Chillgard® LE Photoacoustic Infrared Refrigerant Monitor

The **MSA Chillgard LE Refrigerant Monitor** is a specialised refrigerant gas detection
instrument designed for low-level monitoring in refrigeration systems, chillers,
and HVAC facilities. Manufactured by MSA, this monitor uses Photoacoustic Infrared(
PAIR) sensing technology to detect compatible refrigerant gases and support refrigerant
leak monitoring in suitable environments.

With a minimum detection level of **20 ppm**, the Chillgard LE is designed to identify
refrigerant concentrations at relatively low levels. Depending on the selected model
configuration, it supports single-point diffusion, single-point pumped, or four-
point pumped sampling arrangements.

### Key Features

 * **Photoacoustic Infrared Technology:** Uses PAIR sensing technology for refrigerant
   gas monitoring.
 * **20 ppm Minimum Detection Level:** Designed for low-level refrigerant detection.
 * **Multiple Sampling Options:** Available in single-point diffusion, single-point
   pumped, and four-point pumped configurations.
 * **Refrigerant Compatibility:** Supports detection of several commonly used refrigerants.
 * **Three Alarm Levels:** Includes three software-adjustable alarm levels.
 * **Audible Alarm:** Features an 85 dB buzzer, with a 100 dB option listed in manufacturer
   documentation.
 * **LCD Display:** Provides refrigerant concentration and alarm information.
 * **Durable Enclosure:** Features a water- and corrosion-resistant plastic enclosure.

### Applications

The MSA Chillgard LE Refrigerant Monitor is intended for suitable monitoring applications
in:

 * HVAC and air-conditioning facilities
 * Commercial refrigeration systems
 * Industrial refrigeration plants
