Overview
A single handheld toxic and harmful gas monitor is a handheld detector that detects a single toxic gas and is powered by a replaceable battery. The handheld toxic gas detector is suitable for intrinsic safety gas detectors required by relevant explosion-proof places, with an explosion-proof rating of Exia Ⅱ B T4 Ga. The display adopts an LCD screen display (hereinafter referred to as the display), which intuitively displays the concentration and range of the detected gas. The simple three key operation method makes the operation more concise and easy to understand. The sensor uses imported sensitive components, which have the characteristics of high accuracy and stability.
