Optima 7

Emission Monitoring for Industrial and combustion processes

Rasitech Optima 7: Emission Monitoring for Industrial and combustion processes The Optima 7 is a true 5 sensors Hand Held Analyser suitable for emission monitoring of combustion and industrial processes. It can be equipped with up to 5 electrochemical sensors to simultanously measure O2, CO, NO, NO2 and SO2. Special selected sensors can also be installed for the measurement of Low concentration of NO and CO with resolution down to only 0.1 ppm.

A super bright colour 3.5" TFT display with back light and task oriented menu make possible to display simultaneously all the combustions gases and calculated combustion parameters to easily perform the adjustment and tuning or combustion processes, such as process heaters, gas engines and industrial boilers.

Optima 7 offers real time data transfer via optional Blue tooth or standard mini USB port to a PC or Notebook for data logging and trend analysis.

The newly integrated but removable water trap uses new special coated Teflon filter ensuring maximum protection to dust and preserving the cells life.

Different probe shaft lengths, diameters and temperature ranges ensure high flexibility for all applications. To change, the probe shaft is simply attached to the probe handle. Special flue gas probes for industrial engines are designed to maximise accuracy on NO2 and SO2 reading. In addition, modular industrial probes are available for rugged process conditions.
