Oxygen electrodes
Electrodes for measuring oxygen in solutions. All electrodes except ET1115 must be used with a suitable amplifier like the eDaq EPU354 dO2 isoPod with USB or the EP354 dO2 isoPod and an e-corder system.
The ET1115 can be connected directly to an e-corder data logging system.
The ET1115 can be connected directly to an e-corder data logging system.

Galvanic Oxygen Electrode€143.95The Galvanic Oxygen Electrode uses a sacrificial lead anode to drive an electrochemical reaction reducing oxygen at a platinum cathode. The signal is proportional to oxygen concentration. The electrode can be directly connected to the input of any e-corder model.
Specifications
- Signal: 25 - 35 mV in air-saturated water at 25 °C
- Oxygen consumption: 0.345 pmol O2/s per mV of signal
- Drift: <2% per week at constant temperature and pressure
- Response time: <30 s to 90% of final value at 25 °C
- Body diameter: 12 mm

Micro Oxygen Electrode€630.39The Micro Oxygen Electrode is a Clark style polarographic oxygen electrode. Its small size (and low oxygen consumption) is suited to measuring oxygen concentration in small volumes of solution. It must be used with a suitable amplifier such as the EP354 dO2 isoPod or EPU354 dO2 USB isoPod.
Specifications
- Connector: BNC
- Size: 3 mm OD at tip x 86 mm long
- Response time: <20 s
- Signal: 1.7 nA in air at 25 °C
- Oxygen consumption: 4.4 fmol O2/s in air at 25 °C
