This is the user manual for ZI PRO The CarboProbe ZI pro, based on a ZrO2 ball for the measuring element, allows a very precise value of carbon concentration (and oxygen concentration) in an industrial furnace to be obtained. Its simple design makes ...
The operating principle of an oxygen probe is the comparison of two partial pressures of oxygen in two separate gaseous media. The zirconium oxide (ZrO2) in the measuring cell has lattice defects – in other words, some of the sites that could be ...
There is no difference in the measurement of the probe itself! All probes generate the same millivolts (mV) whether they are in a carbon- or oxygen-rich atmosphere. It is the calculation downstream of the measurement that allows the calculation of ...
Purge air is used on our %C probes (CarboProbe ZI Pro, ZS Pro, ST and ST-E) only to clean the ZrO2 measuring element with a fresh air flow. In heat treatment, the measuring element can become clogged with carbon soot deposits (due to the carbon-rich ...
The equation for calculating %O2 or %C requires knowledge of the temperature at which the measurement is made. This temperature can be obtained by a thermocouple inside the probe or by a thermocouple elsewhere on the furnace. Important: If your kiln ...
