JD5(A) Multi-Parameter Gas Detection Alarm Instrument
Equipped with infrared and electrochemical sensors, along with embedded microcontroller-based intelligent control technology and a color LCD display, this device can simultaneously detect the real-time concentrations of five gases—CH4, CO, O2, H2S, and CO2—in ambient air. It features smart calibration, time and voltage display, intermittent audible and visual alarms, adjustable alarm thresholds, and undervoltage alerts. Additionally, it can seamlessly connect to smart metering and charging management systems for data uploading. The device also boasts built-in Wi-Fi functionality and can store up to 2,000 sets of data, complete with a historical data trend graph for easy analysis.
