MSA Challigard 5000 Refrigerant Gas Monitor
Real-time detection of refrigerant leaks as small as 1 ppm. High-precision refrigerant gas monitor equipped with PAIR technology.
Chillgard 5000 is a next-generation refrigerant gas monitor equipped with patented Photoacoustic Infrared (PAIR) technology developed by MSA. It complies with domestic and international regulations and standards such as ASHRAE 15, EPA, EN 378, and ISO 5149, making it ideal for monitoring refrigerant leaks in mechanical equipment rooms and refrigeration rooms. It reliably detects trace leaks at the 1 ppm level and provides visual and audible alarms both inside and outside the machinery room, as well as automatic control of ventilation. It is resistant to temperature and humidity changes, achieving long-term stability and low maintenance, ensuring the safety of facilities and operators.
