Description Overview GAOTek carbon dioxide detection and alarm Is used for rapid detection of various gas concentrations and environmental temperature and humidity measurements. If the measurement exceeds the limit, it will emit an audible and visual vibration alarm. The NPG40 adopts a 2.31-inch high-definition color screen for real-time display and adopts gas sensors from well-known industry brands. The main detection principles are electrochemistry, infrared, external combustion, thermal conductivity, PID photoion, etc. Advanced circuit design, mature kernel algorithm processing, and unique exterior design. Obtained multiple software works and appearance patents. NPG40 is suitable for detecting gas concentration in pipelines, confined spaces, and atmospheric environments; Gas leakage or high concentration single gas purity with nitrogen or oxygen as the background gas, with over 500 types of gas detected. Features Prevents damage from water vapor and dust. Suitable for high humidity and dust environments. Fast response; sampling distance over 10 meters. Direct detection of gas at 1.10 lb to 41 lb pressure. 31-inch color screen. Displays real-time data, alarms, time, temperature, humidity. Intuitive menu navigation with high-definition graphics. Customizable capacity. Supports multiple storage modes. Optional RS 485 communication.
