Product Description

Gas Detection System

Our manufactured Gas Detection System is easy to use and handle and is highly acclaimed for durability and flawless performance. We are established as one of the leading supplier of online gas detection system based in India. Our product is high sensitive equipment and is compact in its structure and design.

Features

  • Gas leakage is monitored during power failure or other life line failures (on models with a built-in back up power supply).
  • Constantly monitors for 30 minutes after a power failure and then erratically monitors for 2 days, the intermission between observations depends on the number of detection points. (NV-500)
  • Tested normally in a seismic qualification test equal to intensity of 7 on the Japanese 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.
  • Shows gas concentration at the time of an alarm as a glance.
  • Battery life check function measures by one-touch operation.
  • Easy accessible to change the alarm set value. (Δ∇ 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
