Product Description

GDQL-H Hand-held Hydrogen Gas Leak Detector

General Information
GDQL-H Hand-held Hydrogen Gas Leak Detector adopts catalysis principle sensor and intelligent signal processing system. It has features of long service life, high accuracy and easy operation, suitable for continuous detection of the concentration of combustible gases such as alkanes, alcohols and organic volatiles in the working environment, and can be widely used in petroleum, chemical, natural gas, fire protection and other industries.

The sensor directly reacts with the measured gas in the environment in a diffusion manner to produce a voltage signal with linear variation. The signal processing circuit is composed of multiple integrated circuits based on intelligent chip. The output signal of the sensor is processed by filtering and amplification, analog-to-digital conversion, model operation, etc., and the concentration value of the measured gas is directly displayed on the LCD screen. The instrument can set a secondary alarm. When the gas concentration reaches the preset alarm value, the instrument will send out sound and light alarm signals of different frequencies according to the alarm level. The indicator light of the instrument flashes every 10 seconds or so, indicating that the instrument is working normally. When the battery voltage drops to a certain level and needs to be recharged, the display screen will show an undervoltage sign to prompt the user to charge.
