Hanging Multi Parameter Detection And Alarm Instrument For Precise Monitoring

1,Overview
The JD4X suspended multi-parameter carbon detection alarm instrument can continuously detect the concentrations of methane, carbon monoxide, oxygen and hydrogen sulfide in the air, and can trigger an alarm when the limits are exceeded. The detector uses an 8-bit microcontroller as the control unit and employs high-precision detection components, featuring high sensitivity and fast response. The screen displays the data using a four-digit digital tube, which is clear and reliable. When the detected concentration of the target gas in the environment reaches or exceeds the preset alarm value, the detector immediately issues an audible and visual alarm to alert us to take safety measures in time, ensuring the safety of life and property. The detector has been reviewed and inspected by the designated national legal authority. The detector is suitable for all workers, including professional technicians, operators, and managers.
