Electrochemical oxygen sensor 332K25

process

Mod.332K25x is a galvanic cell for the measure of O2 in air with long term life expectancy and an excellent chemical durability. The measure is not affected by CO2. Typical application of these sensors Mod.332K25A and Mod.332K25B for fixed installation is the O2 monitoring in bioreactors, oxygen incubators, anesthetic instruments, respirators, oxygen enrichers. Also, the sensors can be used for safety purposes to detect oxygen levels in ambient air. Mod.332K25C and Mod.332K25D, in conjuntion with the portable O2 meter Series HANDY 3000, allow to monitor O2 concentration in tanks, vessels etc. Mod.332K25E, again in conjuntion with the portable O2 meter, can be worn by the operator. Electrodes: 2 electrodes galvanic cell Measuring range: 0÷100 % O2 Accuracy: ±1 % f.s. (when calibrated at both 0% and 100% O2) Operating temperature limits: from 5 to 40 °C Operating pressure limits: atmospheric Relative humidity limits: 10% to 90% non condensing Sample air exchange on the sensor: higher than 200 - 300 ml per minute Signal generated by a new cell under test conditions: 10.0 ÷ 15.5 mV Standard test conditions: 21% O2, P = 1013±5 hPa; T = 25°C±1°C; UR 60% ±5% Offset: V0 ≤ 0.5 mV
