GD3(B)
GD3(B) multi-parameter sensor for mining is mainly used to monitor environmental parameters such as underground gas in coal mines, and can measure up to three parameters of methane, carbon monoxide and temperature at the same time. As an intelligent monitoring instrument, the sensor is stable, reliable, and easy to use. Functions such as zero-setting, accuracy adjustment, and alarm threshold setting can all be achieved through remote control, and equipment can be integrated with the coal mine safety monitoring system for gas parameter monitoring.
