Polarographic Oxygen Sensor
DISSOLVED OXYGEN SENSOR (150 bar):
Polarographic sensor, with replaceable cap for membrane support, pressure compensated. Negligible stirring effect, pump is not needed.
DISSOLVED OXYGEN SENSOR (700 bar):
Polarographic sensor, with replaceable cap for membrane support, pressure compensated. Negligible stirring effect, pump is not needed.
DISSOLVED OXYGEN SENSOR WITH ANALOGUE OUTPUT:
The sensor consists of a POM-made housing with integrated electronic device, exchangeable sensor head (with possibility of membrane and electrolyte exchange) and an underwater connector.
N.B. Dimensions are in millimeters.
| Type: | Polarographic sensor with platinum-iridium cathode and silver anode (99.99%). |
| Output current: | Typical 60 +/- 15 nA in air @ 20°C (green membrane). |
| Zero output current: | Less than 50 pA, with nitrogen. |
| Polarization voltage: | 650 mV DC. |
| Range: | 0..50 ppm. |
| Drift: | 5%/month typical. |
| Response time: | 3 s (green membrane @ 20°C). 0.9 s (blue membrane @ 20°C). |
| Operating pressure: | 150 bar. |
| Output connections: | Two 0.4 mm insulated copper wires. |
| Mounting: | Through 12mm hole with two 0-ring seals (Parker 2-12). |
| Weight: | 30 gr. |
| Body: | Black plastic (PPS). |
