BH-90A Single Gas Monitor

Overview

Single Gas Detector

The BH-90A Portable Single Gas Detector is a cutting-edge device designed for continuous monitoring of combustible and toxic gases, ensuring the safety of workers and preventing potential facility damage. Its compact and portable design makes it suitable for diverse applications, such as detecting gas leakage in underground pipes and mines. The detector utilizes natural diffusion for detection, employing an excellent-quality sensor that provides high sensitivity and reproducibility.

Equipped with an advanced MCU controller, the BH-90A is user-friendly, allowing for easy operation. The shell is constructed from special high-strength material with anti-smooth rubber, making it both water-proof and dust-proof. This rugged design ensures durability in challenging environments.

Versatile Gas Monitor

The detector offers versatile gas detection capabilities, including combustible gases such as CH4, C3H8, H2, toxic gases, oxygen, and even rare toxic gases like ammonia, NO, PH3, NH3, NO2, HCN, and SO2. Customers can specify their requirements in advance, adding a layer of customization to meet specific needs.

Key features of the BH-90A include adjustable low and high alarm levels, calibrating level adjustments, high concentration protection for combustible gases, and a self-test function for the combustible gas sensor. The device also features a visual and audible alarm with vibration, enhancing its effectiveness in alerting users. Additionally, the advanced self-examination and self-renovation function, along with password management, contribute to the prevention of wrong operations.

The detector operates on a DC3.7V Li battery with a capacity of 1500mAh, providing a working time of at least 8 hours continuously. Charging time is efficient, ranging from 4 to 6 hours. The sensor has a life expectancy of two years, ensuring long-term reliability. With an IP65 protection category and a weight of approximately 130g (including the battery but excluding accessories), the BH-90A is a robust, reliable, and versatile solution for gas detection in a variety of industrial settings. Trust in its accuracy, durability, and advanced features to enhance workplace safety.
