Description

BX172 portable gas detector can continuously detects the content of combustible gas or toxic gas. It is used for anti-explosion and toxic gas leak alarm in underground pipe or mines, especially confined space, which keep the people safe and prevent equipments from being destroyed.

The detector with large LCD detects the gas by pump sampling. And there are different sampling probes attached, which is convenient for detecting in different environment. And the high and low alarm level is adjustable (there is Time-weighted average based on a 15-minute period (STEL) and Time-weighted average based on an 8-hour workday (TWA) alarming function for toxic gas). It could check the concentration, STEL and TWA, test extreme level etc. User could open or shut the vibration alarm function according your application. When alarming there is visible and audio warning and back light shall be activated automatically. The screen also displays the relative indication to help user to realize the alarming type.  During the operating or alarming, the back light shall be activated automatically. The mark in the LCD makes the operation simple and convenience.
