AO2 product parameters (1) the output: 9-13 mv in the air (2) the range: 0-100% O2 (3) accuracy: 0.01% O2 (4) the expected service life: 360000% O2 to pump in 20 and 40 286000% O2 in hours, or in the air in the STP service life of two years (5) T90 response time: < 5 seconds (6) T99.5 response time: < 40 seconds 100% of the oxygen in signal (7) : 100 + / - 1% (8) linear: 0-100% O2 (9) of zero offset value: < 20 & micro;V Temperature range (10) : - 20 to + 50 (11) temperature compensation: < 2% change form 0 to 40 (to) (12) differential pressure range: 0-500 mbar Max Absolute pressure range (13) : 500-2000 mbar (14) relative humidity range: 0-99% non condensation (15) the output drift for a long time: < 10% signal loss per year (16) it load hold minutes: 10 k (17) giant: have the from delivery date AO2 the output of the sensor with temperature changes, but gradually set thermistor to compensate for these changes. A thermistor for AO2 very stable output in A wide range of temperatures. Use on the oxygen index test apparatus AO2 PTB - 18.10Oxygen sensor is a kind of consumables, when it is exposed to air, began to chemical reaction happened. Shelf life Under normal circumstances, the use of valid for one year. Oxygen sensor to the the original packaging must be sealed, normally sealed in filled with nitrogen gas sealing plastic packing. The best temperature for save "0 The degree of ~ 20 The degree of "In between. British CITY AO2 PTB - 18.10 oxygen sensor, informs in all kinds of related to oxygen test instrument, to the as: motor vehicle exhaust testing instrument;Exhaust gas environmental testing instruments;The oxygen index test instrument.
