This analyzer is an excellent solution for oxygen measuring in flue gas in the radiant section at high temperature. It guarantee a very fast response time and an accurate measure which is not affected by the outside air, which normally penetrates between the combustion chamber and the stack. The accurate compensation of the output of the zirconia cell to the temperature of the process eliminate any Zero and Span drift. Specific test carried out on purpose have demonstrated a stability within 0,1% 02 during twelve months.

The probe, totally ceramic, is unaffected by the most aggressive atmosphere and with high particulate

content, like the combustion chamber of incinerators of contaminated liquids and gases.

The very competitive price is compatible with the high performance due to the simple construction of the

analyzer.

The equipment is composed by the probe (produced in three different lengths), the field transmitter with active barriers in Ex housing and the calibration kit. The protection is: EEx d IIC 2GD c T6 fully ATEX approved - IP 65. The probe, that has no electric power supply, is an intrinsically safe device. It generates signals lower than the dangerous limits according the safety norms.
