The KDZD400 is an intrinsically safe, portable multi-gas detector designed for hazardous environment monitoring. It uses high-performance imported sensors to detect up to 5 gases (combustible, toxic, O₂, CO, H₂S, etc.) with a pump-suction sampling method for fast response. The 2.4-inch IPS color LCD displays real-time concentrations, while sound, light, and vibration alarms alert users to over-limit conditions. With IP65 waterproof/dustproof protection, a rechargeable lithium battery, and data storage for 500 records, it is ideal for field safety monitoring in industrial and municipal applications.
