Alarme de détecteur de gaz d'aspiration de la pompe OT135

Description

OT135 pump-suction gas detector is an all-in-one gas detector that can continuously measure combustible, O2, CO, H2S and other toxic gases in ambient air. It can detect up to 5 gases at the same time. The waterproof design of the instrument is combined with a rubber shell to meet the most demanding requirements of harsh environments.

The detector uses a pump-suction method to detect gas, and the sensitive element uses a high-quality gas sensor with excellent sensitivity and excellent repeatability; the instrument uses an embedded microcomputer control, which is simple to operate, fully functional, highly reliable, and has multiple adaptive capabilities. It uses a graphic LCD display, which is intuitive and clear.
