OT139 สัญญาณเตือนการตรวจจับก๊าซแบบมัลติฟังก์ชั่น 8-in-1 - Otywell

คำอธิบาย

The OT139 portable gas detector adopts dot matrix display technology and switches between Chinese and English interfaces, which can simultaneously detect 1-8 types of flammable and toxic harmful gases. It adopts a group type sensor element, which can be replaced with different sensor types anytime and anywhere. The detection results are displayed on the screen simultaneously.

TheOT139 multi gas detector is equipped with a English LCD display interface and audio and visual alarm prompts, which can adapt to concentration monitoring in more complex environments. This product is suitable for various places such as chemical, pharmaceutical, municipal, water treatment, telecommunications, archaeological laboratories, cold storage, brewing, ฯลฯ.
