Unigas flue gas analyzers
The Unigas instruments are compact flue gas analyzers for combustion analysis, boiler tuning, emissions monitoring and related tests and inspections. The basic analyzer, Unigas 1100,  uses two electrochemical sensors to read the oxygen and carbon monoxide concentrations. These values are used together with flue gas and combustion air temperatures to calculate the efficiency, excess air and CO2 compliance.

The 2200 series adds an optional NO sensor and can calculates the NOx. This sensor can be added to the system as a later date if needed ( purchase the 2200-1 now and add NOx later).

The 4400 series adds an NO2 sensor so that NOx can be calculated from independent readings or NO and NO2. Alternatively the unit can be supplied with an SO2 sensor (4400-2)The Unigas can be used for most common fuels including natural gas, LPG, gasoil and kerosene, coal, coke and anthracite. Up to six additional fuels can be programmed by the operator.

The gas sensors are built into the handset. The gas is sampled via a probe which is inserted into the flue. A small pump in the handset draws the flue gas into the analyzer. The probe includes a K type thermocouple sensor and there is also an additional separate connection on the handset for an external resistance thermometer to be used for the ambient air temperature.

The Unigas combustion gas analyzers can be used with up to  four sensors to measure sulfur dioxide SO2 and Nitrogen Dioxide/Oxide NO2/NOx combustible concentration. Other external sensors can be used to measure room temperature, RH ( Relative Humidity ), and ambient carbon monoxide ( CO ) safety monitoring.
