Product introduction
1. Product description of explosion-proof 2-channel gas controller MP220EX
MP220EX is a 2-channel, explosion-proof, wall-mounted controller certified for use in Class 1, Div 1, Groups C and D (optional B) hazardous areas. It can be operated with a magnetic wand without opening the cover or disturbing the hazardous area. Three types of sensors (fixed, electrochemical, and catalytic) are available to monitor over 150 toxic or combustible gases. It has automatic calibration: simply apply gas, and the smart controller will perform all necessary calibration and adjustments. Each sensor channel has its own digital display, 3 alarm set points, and individual or shared alarm relays.
