KLW6LM (A) methane gas alarm miner's lamp 
 Product Overview 
 1.1 Features 
 KLW6LM (A) methane alarm miner's lamp (hereinafter referred to as alarm miner's lamp) lighting part of the super bright LED cold light source, work, low fever, and a high photoelectric conversion rate; batteries using manganese lithium-ion batteries are smaller, light weight, equipped with charge and discharge protection system, safety and environmental protection. Coupled thermal catalytic component for the methane probe peripheral circuits optimized composition of the ore with a new methane alarm miner's lamp, lighting and methane continuous detection limit alarm dual function. 
 Alarm miner's lamp according to high, small size, light weight, long time lighting, maintenance-free, charge-discharge no memory effect, long life, reliable performance, reasonable structure, set within a miner's lamp charge controller constant current constant voltage charging mode can be directly installed in all types of mining cap lamp charging stand charging, do not need any changes to the old charging rack, easy to operate.
