Product Overview
The B portable gas detector is a handheld detector that detects a single gas and is powered by a lithium battery.

Intrinsically safe gas detectors suitable for requirements in relevant explosion-proof locations.

The portable gas detector uses natural diffusion sampling to detect gas. Users can select appropriate probes according to different requirements of the environment, making the measurement more convenient.

The display adopts a screen display (hereinafter referred to as the display) to intuitively display the concentration range of the detected gas.

The simple three-key operation makes the operation more concise and easy to understand.

The sensor uses imported sensitive components and has the characteristics of high precision, accurate measurement, strong interchangeability and high reliability.

Sensor protection, the sensor filter is made of stainless steel particles with good air permeability.


Main features

High measurement accuracy
◆ Type B gas detector uses a high-speed processor, which can handle system tasks quickly and accurately to ensure detection instrument reliability.
◆ Using imported gas sensitive components, it has high precision and reliability, fast response and recovery time, good gas selectivity and strong anti-interference ability.

Intuitive display
◆ LCD display can display gas concentration in real time.
◆ Good earthquake resistance.

Low power consumption
