Gas Detector, LEL Gas Meter

Descrição de Gas Detector, LEL Gas Meter

This portable multi-gas detector simultaneously monitors carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2), and combustible gas (LEL) concentrations in the surrounding environment with professional accuracy. It features a large backlit color LCD display for easy reading and provides audible, visual, and vibration alarms when any gas concentration reaches the preset alarm level. You can configure the alarm thresholds and the automatic shutdown time. The device supports connection to an external sampling pump for use in confined spaces, making it ideal for shipping, mining, oil exploitation, chemical processing, gas pipelines, tunnel construction, coal, metallurgy, paper, fire services, municipal, textile, and other industries.

Technical specifications: Detection range for CO is 0-999 ppm (resolution 1 ppm), H2S 0-500 ppm (resolution 1 ppm), O2 0-30% (resolution 0.1%), and combustible gas 0-100% LEL (resolution 1%). Response time is less than 20 seconds. The unit operates at 3.7 V with a current of 230 mA, powered by a BL-9C rechargeable battery that lasts up to 6 hours (no alarm). Operating temperature range is -10C to 50C, storage temperature 0-40C, and humidity 15%-95%. Short circuit current is 3 A, maximum open circuit voltage 4.2 V. Dimensions are 75 x 138 x 43 mm. The robust ABS housing is as shown in the product photos. Package includes one gas detector only. Please note that slight color variations may occur due to display settings, and a measurement tolerance of 1-3 cm is possible.
