OT139 Multi functional Gas Detector

The OT139 portable gas detector adopts dot matrix display technology and a fully Chinese interface operation, which can simultaneously detect 1-8 types of flammable and toxic gases. It uses modular sensor components that can be replaced with different sensor types anytime and anywhere, and the detection results are displayed on the screen at the same time.

The OT139 multi gas detector is equipped with Chinese LCD and audio sound and light alarm prompts, which can adapt to concentration monitoring in complex environments. This product is suitable for various places such as chemical, pharmaceutical, municipal, water treatment, telecommunications, archaeology, laboratory, cold storage, brewing, etc.
