Product Description

With the assistance of our knowledgeable professionals, we are able to manufacture, export and supply an extensive assortment of Cng Gas Detector. Provided detector is precisely manufactured by making use of the superior grade basic material with the aid of pioneering methodology under the strict direction of our technocrats. It is extensively used at industrial plants, refineries, etc to detect the presence of harmful gas. Besides, this Cng Gas Detector can be availed from us at affordable rates.


  • Sturdiness
  • Fully configurable
  • Easy to operate
  • Excellent detection and monitoring
  • Monitors gas leakage even during a power failure or other lifeline failures.(on models with a built-in backup power supply)
  • Continuously monitors for 30 minutes after a power failure, then intermittently monitors for 2 days. The interval between observations depends on the number of detection points. (NV-500)
  • Continuously monitors for 30 minutes after a power failure. (NV-400/410/600HS)
  • Operated normally in a seismic qualification test equal to intensity of 7 on the Japanese earthquake scale. Earthquake-resistant design considering great earthquakes.
  • A plastic molded case which contains the electronic circuit is hard to break and has substantially improved insulation. The case structure has been refined to increase the strength.
  • Gas concentration at the time of an alarm is shown at a glance. NV-410 shows a scale of 0 to 10. (No unit)  Battery life can be measured by one-touch operation. (Battery life check function)
  • Very easy to change the alarm set value. (+key)
  • NV-500 has extremely easy zero adjustment and span adjustment. (One-touch calibration function)
  • Wide operating voltage range of 85-264V.
  • NV-500 comes with Zero suppression function.
