Simultaneous and continuous measurement of up to 5 components among: NO, SO2, CO2, CO, CH4, N2O, and O2

Ideal for flue gas monitoring in incinerators and industrial furnaces.

Optimum measurement system for combustion exhaust gas from refuse incinerators and boilers or different industrial furnaces, this Fuji Electric ZKJ infrared gas analyser system is capable of measuring, but not limited to, CO, SO2, CO2, CH4, NO and O2 components in sample gas, with up to five different components, including O2 that can be measured simultaneously.

High reliability and sensitivity are achieved via the twin detector which allows for mass flow. This design allows for the device to be stable in operation due to its ability to provide measurement readings without interference. There are no shortage of functions on this device including automatic calibration, single-touch calibration, remote measurement, lower/upper limit alarm, O2 conversion, range identification and avg. value computation. Australian Dynamic Technologies can help you configure the various applications to match your specific use.

With a microprocessor built in to an easy-to-see large LCD unit, observing the indications of all channels is fast and simple. All in all, this is one impressive gas analyser, speak to us today for our best price
