Bacharach added 22 halogen refrigerants for its MGS-400 gas detectors in industrial gas leak-monitoring applications. They include: R1234yf, R1234ze, R134a, R22, R32, R404a, R407a, R407C, R407f, R410a, R422, R422D, R427A, R434A, R448A, R449A, R450A, R452A, R454A, R454C, R507a and R513A.

The MGS-400 gas detector uses three different sensor types, depending on the measurement range, temperature and gas types when detecting for hazardous refrigerant leaks. It helps to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378 inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk-in freezers.
