NV - 400/500 is a latest technology and easy to operate gas detection equipment that can be used to detect and monitor gas leakage from LPG manufacturing, storage and consumption facilities from an accident due to gas leakage. Superior in reliability and accuracy, NV - 400/500 works on the principle of catalytic combustion and can be used to detect gases in the range of 0 - 100% LEL.

Principle of detection Catalytic combustion type Gas to be detected LPG leaked in the air ( i-C4H10 standard ) Detection range 0 to 100% LEL Gas concentration indicator LCD bar graph meter With back light ( with scales to read preset alarm value and peak hold) Standard preset alarm value 24% LEL ( iso-butane 0.43vol% ) The alarm point can be freely set using the. Keys. Alarm accuracy Within ?25% of the preset alarm value Response time Within 30 seconds when gas concentration is 1.6 times more than the preset alarm point ( Suction type: The delay due to sampling pipe length should be exempted.) Alarm indication Individual alarm lamp Alarm sound Red blinks In ease of an alarm. Self-holding. Lights up when buzzer stops. Intermittent alarm sound- Self-holding. Consecutive alarm method.
