Pico-Ion UHP PPB Oxygen Sensor | AII1 Vietnam | AII Vietnam | Advanced Instrument Vietnam | Pitesco Vietnam

The unique features of this breakthrough in sensor technology are a proprietary sensing electrode material and a gas chamber design that maximizes the rate of reaction above the sensing electrode while minimizing both the amount of oxygen that dissolves into the electrolyte and the temperature dependence of the sensor’s output, thereby ensuring long-term stability. This compact self contained package requires no maintenance or periodic addition of chemicals and is easily replaced at the end of its 15 month service life. The capabilities of the resulting sensor are:

Accuracy:	+1% FS under constant conditions
Sensitivity:	<0.5 PPB
Noise level:	<0.2 PPB
Stability:	<1 ppb over temperature fluctuations of +10ºF
Low range:	0-100 PPB full scale
Response time:	90% of full scale in <60 seconds
Recovery to:	10 PPB from 1 minute exposure to 9 PPM in 15 minutes 1 PPB from 1 minute exposure to 9 PPM in 60 minutes 1 PPB from 5 minute exposure to 1 PPM in 30 minutes
Expected life:	15 months in normal applications
