Description
The OT137 multi-gas alarm instrument adopts color liquid crystal display technology, and can detect 1 to 6 kinds of gases simultaneously. Different gas sensors can be configured for detection. The S318 multi-gas alarm instrument is equipped with audio, sound and light, and vibration alarm prompts, and the real-time concentration display can adapt to concentration detection in a more complex environment. This product is suitable for a variety of industrial manufacturing places such as chemical and pharmaceutical, municipal, water treatment, telecommunications, archaeology, laboratories, cold storage, brewing, steel, gas, etc.
The OT137 multi-gas detector adopts a large-capacity rechargeable lithium-ion battery, and this machine can simultaneously and real-time display the concentrations of up to 6 gas types, which is an essential detection tool for work safety supervision and inspection.
