The GA-3500-series Smart Gas Analyzer is a micro controller based gas transmitter with LED display, that continuously monitors Oxygen / Toxic / Combustible gases in PPM / %V/V / %LEL / PPB depending upon the gas selected.

It is ideally suited for harsh environment in industries where human interference is not possible in toxic or combustible gases area. It is capable of displaying the gas concentration and transmits the data to control units through standard 4-20 mA output.

It comes with optional relays allowing the unit to directly control the external devices such as fans, pumps, alarm hooter, warning lamp etc. It also comes with optional RS-485 with MODBUS RTU Protocol which allows the unit to communicate with control devices.

All the user adjustable parameters can be accessed by using push button switches, The two setup modes allows you to display and change the setup and calibration settings.

They are available in weatherproof, flameproof and panel mounting type of enclosures.
