Abhitron india has developed a sophisticated digital readout microprocessor based gas detector for chlorine, sulphur dioxide, carbon monoxide, hydrogen sulphide, nitrogen dioxide, hydrogen cyanide, hydrogen, ammonia, ozone, etc, for continuous monitoring in the industries. The microprocessor control unit has facility for three set point with three independent relays and nine keys operations like hystesis, increase and decrease of the set points, alarm reset, relay reset, changing of decibel point. The customer can also have standard set points, setting for one and two relay and third relay is optional at an extra cost. The controller is din type with mounting sockets which can install in the control panel. The company also supplies 4-20ma dc output for recorder, second display and computer with a timer switch will be given since the gas sensors requires 90 seconds to settle that at initial stage no alarm will be there. These gas detector has a resolution of 0.1 ppm and less than 30 seconds response time. The gas sensors are iso 9000 approved which are in a anticorrosive flameproof cmri approved enclosure suitable for i, iia & iib group is2148 and optional weatherproof/ flameproof dgfas approved also can be provided.
