OxyPink
Zirconia Flue Gas Analyser
OxyPink is a highly innovative Zirconia probe, the only one able to measure residual O2 concentration in flue gas in the whole range of temperature from 0°C to 1250°C thanks to a simple but very advanced integral heating system, managed by the external electronics.
Able to withstand the most severe and dusty process conditions, this resilient in situ analyser, completely ceramic-made, has been specifically designed for cremators and incinerators, but it the ideal solution for all combustion processes where the probe must be always in line, whichever is the flue gas temperature.
Measureable Gas
Oxygen [O2]
Main Features
Extreme Roughness
- Wetted parts in ceramic materials (Zirconia and pure alumina)
- Resistant to corrosion by acid & aggressive substances, to abrasion and to the alternation of oxidant and reducing conditions
- External flanged installation & protection tube (option) warranty extra protection in case of huge dust amount in the process
Easy to Use
- Immediately ready and always in line, at whichever process temperature
- Direct insertion into the post-combustion chamber or in the chimney
- Possibility to verify the calibration without removing the probe from process
- Calibration (with air flowing) simply pushing one button or by an external contact.
- Ideal for use in advanced furnaces with remote control
- Integral thermocouple
Low Costs of Ownership
- Really in situ measurement
- No sampling system required
- Sensor on the tip and no gas circulation
European Compliance
- Low Voltage Directive 2014/35/EU
- EMC Directive 2014/30/EU

Measuring Principle
The measuring principle on which the analysis is based is linked to the use of Zirconium Oxide which, at high temperatures, can behave like a solid state electrolyte, developing an electromotive force (E.M.F.) on two electrodes placed in contact with different O2 concentrations (partial pressures), proportional to the temperature in Kelvin degrees (°K) and to the logarithm of the ratio between the two pressures PO2’ and PO2” in accordance with Nernst’s well-known ratio:
E = RT / nF (ln P02’ / P02“)
Where: R = Perfect gas constant (8,31 Joule/degree bulk)
F = Faraday’s constant
T = Absolute temperature in °Kelvin
n = 4
