Single-gas detector
Type: DX-BH-90
Introduction
DX-BH-90 portable single gas detector can make continuous detection to combustible and toxic gases. The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate.The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof.
DX-BH-90 is a high price portable single gas detector. It adopts the mainstream 8 bit micro control technology. It has quick response speed, high precision, good stability and repeatability and simple operation. It is compact and highly waterproof, and it can withstand the test of harsh environment. Bring your flashlight to facilitate temporary operation in dark environment. Built in 1500mA large capacity rechargeable lithium battery, super long standby; using 12864 dot matrix LCD screen can perfect display of various technical indicators and gas concentration value, can view historical alarm data, and have data storage function. It is suitable for explosion-proof, toxic gas leakage, leakage, underground pipeline, mine, metallurgy, power plant, chemical, tunnel, tunnel and other places, effectively preventing the occurrence of poisoning accidents, ensuring the safety of the workers' lives and preventing the damage of the equipment.
