Advanced Portable 4-in-1 Gas Detector with Pump Suction and Diffusion – GAOTek

Description Overview GAOTek’s advanced portable 4-in-1 gas detector with pump suction and diffusion is engineered with intelligent gas detection technology using advanced large-scale integrated circuits and proprietary digital-analog hybrid communication. This device detects multiple gases through natural diffusion or pump suction and uses high-quality sensors for excellent sensitivity and consistent color repeatability. Designed for industrial on-site safety, it features a durable shell made from high-strength engineering plastics and anti-slip rubber, providing waterproof, dustproof, and explosion-proof protection. This product offers reliable, easy-to-maintain gas monitoring for CO, H2S, O2, and combustible gases.   Features Advanced MCU control with low power consumption Advanced integrated circuit technology with embedded microcomputer control Adjustable low and high alarm level Adjustable calibrating level High concentration protection for combustible gas Self-test for the combustible gas sensor Visual and audible alarm with vibration   Technical Specifications Power Supply 3000 mA Rechargeable Lithium Battery Weight 0.74 lb (0.335 kg) Size 5.2 in x 2.6 in x 2.2 in (13.3 cm x 6.6 cm x 5.5 cm) Detecting Range CO: 0 to 1000 ppm H2S: 0 to 100 PPM O2: 0 to 30 % vol Combustible Explosive Gas (Ex to LEL to CH4): 0 to 100 % LEL Display Error ≤ ⼟ 5 % FS Response Time T ＜ 30 s Indication Method The LCD displays real-time data and system status, while the LED and beep indicate alarms, faults, and low voltage.
