GMA200-MGSS
GfG GMA200-MGSS gas sampling system
Gas sampling system with an integrated diaphragm pump, sequentially monitoring up to 3 gases at 6 measuring points.
About GMA200-MGSS
GMA200-MGSS is a compact wall-mounted gas sampling system with an integrated diaphragm pump (flow rate about 0.5 l/min) that draws in samples and sequentially monitors up to 3 gases or vapors at up to 6 measuring points. The sensor block holds up to 3 sensors, 2 electrochemical or infrared sensors combined with 1 catalytic combustion sensor, for measuring oxygen, toxic gases and combustible gases up to the LEL. The unit suits hot, humid, cold or dusty areas where installing transmitters on site is difficult or impractical. Via RS-485 it can be expanded with up to 12 external transmitters and GMA200 series relay modules.
