Portable voice type multi gas detector is a safety device that can continuously detect the concentration of leaking gas.
It adopts advanced integrated circuit technology, embedded computer control, high-quality imported gas sensors, with excellent sensitivity and repeatability.
It uses dot matrix LCD display to support Chinese-English interface and Chinese-English voice prompt, so that users can quickly understand the product and use and maintain it simply.
High-strength engineering plastics, good seismic resistance, high strength, high-grade atmospheric appearance and dust-proof, waterproof and explosion-proof function, etc.
The detector is widely used in petroleum, chemical industry, environmental protection, metallurgy, refining, gas, biochemical medicine, agriculture, fire protection, Archaeology and other industries and places that need safety monitoring for toxicity and harmfulness, explosion prevention. The detector can effectively predict the concentration of dangerous gases and alarm, so as to ensure the safety of workers and production equipment.
