BX170 hanwei Gas detector

The instrument adopts advanced ultra low power 16 bit microcontroller
The ultra wide viewing angle LCD display
It can be set high and low alarm, two alarm, display alarm categories
The calibration density is adjustable, convenient user calibration
The high concentration of combustible gas sensor protection, fault self checking function
The battery undervoltage tip
It provides real time clock display
The modular sensor, easy to maintain
The automatic calibration function, reduce the detection error
The two grade three alarm (sound, light and vibration), is not easy to ignore
The toxic gas and STEL and TWA alarm
The power on self test function, and has advanced the self diagnose and self repair function
The password management functions, important operations require password authentication, effectively prevent the misoperation
The antiskid design, durable

The intrinsically safe apparatus
