Carbon monoxide gas transmitter MY F101

sulfur dioxideoxygenhydrogen

Product overview
The MY F101 series gas detection transmitter uses advanced large-scale integrated circuit and mixed digital-analog communication technology. It is an intelligent fixed gas detector with communication, self-diagnosis and remote alarm capabilities, designed for industrial applications such as petrochemical, metallurgy, refining, gas transport/distribution and biochemical sectors. Compatible with PLC and DCS control/alarm systems for remote monitoring and control.
