Product Description

Outfitted with swift -response sensors, this Gas Leak Detector Alarm is the toughest product available with high durability and efficiency features. This is ideal to provide real-time happening awareness to the workers, members, supervisors as well as safety managers to make them provision for safety of everyone. Its digital sensors can sense gases faster than the any other products ensure swift result when any gas leakage is detected. In addition, its alarm alerts about the potentially dangerous situations. Its rugged design is developed to withstand high temperate, pressure and other adverse environmental conditions. Moreover, it can also easily tolerate a drop of more than 18 ft. without any abrasion and wear. With simple drive circuit, it ensures load resistant features for years. 

Gas Alarm Features:

  •  Provides a fast and reliable output by using Electro Chemical / Pellister Sensor Technology.
  •  Optimized for detection of smallest leak of Oxygen, Toxic and Combustible Gases.
  •  Highly resistant to poisoning and etching.
  •  Capable of detecting down to PPM, %LEL & %V/V.
  •  Digital display of Gas Concentration on LED Display for GA-3500, Standard 4-20mA signal output with configurable range.
  •  Easy handling and programming with 3 keys for Weatherproof Models.
  •  Can be programmed using Remote Control from 10 meters in line of site distance.
  •  Non - Intrusive programming for Flameproof model using Magnetic pen.
  •  Password protected programming with password changing facility.
  •  One man Auto Software Gas Calibration.
  •  Optional Alarm relay contacts with two configurable Alarm levels & one Relay for fail safe relay.
  •  Optional STEL and TWA set points can be configured for Toxic Gases.
  •  Optional RS-485 communication port with MODBUS RTU Protocol.
