Product Description
Paint Shop Oven Fixed Gas Monitor NV 400/500

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.

  • Seismic technology
  • User friendly operation
  • Auto zeroing
  • Simple span adjustment
  • 2 days backup power supply devices
  • Super thin depth, space saved indicator / alarm unit design.

Indicator / Alarm unit Model Number of mountable detectors ( an even number from 2 to 12)
Number of detectors mounted (from 1 to 12 )
A: Without a backup power source,
B: With a backup power source
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.
Failure indication Individual power lamp Alarm sound Green lamp goes off and orange- lamp lights up when the sensor is disconnected. Intermittent alarm sound. Consecutive alarm method.

Painting color Munsell 2.5 PB7.0/1.0
External alarm barrier Option : BT-150 intrinsically safe construction ( 2G4)
Maintenance function Maintenance mode 1 (Mainte lamp lights up, BATT voltage indicates " =1".)
Alarm lamp Blinks for about five seconds when the preset alarm value is reached then lights up.
Alarm sound: Intermittent sound. Automatically stops.
External output: All contact output and voltage output stop.
Peak hold: Peak hold is indicated when indication exceeds 10% LEL.
Zero suppression: Canceled in the maintenance mode.
Auto span: Peak hold value is automatically corrected to the calibration gas concentration value: simply by pressing a button.
Maintenance mode 2 ( MAINTE lamp lights up, BATT voltage indicates "=2".)
Auto zero and auto span functions are canceled.
Peak hold value of maintenance mode 1 is indicated.
Analog zero and span adjustments are carried out in this mode.
