Polarographic dissolved oxygen probe DO-958-Q: 0 – 20 mg/L, 5 – 40 °C, ABS body Φ12 × 120 mm, 1 m cable, 4-pin aviation connector. For the 310F / 400F / 500T / 510T series meters (0 – 50 mg/L).
The dissolved oxygen probe DO-958-Q is a polarographic probe with an ABS body (Φ12 × 120 mm), a 1 m cable and a 4-pin aviation connector. It measures 0 – 20 mg/L at 5 – 40 °C. In addition, it suits samples without bubbles — for example rivers, dams, boreholes and treated water.
On the 310F, 400F, 500T and 510T series meters — for example the M310F multi-parameter analyser — the manufacturer rates it to 0 – 50 mg/L. For service, you need the DO-958 membrane cap, dissolved oxygen electrolyte (100 mL) and a zero-oxygen standard for calibration.

Specifically, the table lists the manufacturer’s ratings. Therefore, ask us if your application needs a value that is not shown.
The probe measures dissolved oxygen in rivers, dams and reservoirs. In addition, it serves aeration-basin and effluent checks, aquaculture, and boiler-feed and process-water monitoring.
Hadron Group runs its own water laboratory in Pretoria. In addition, we supply analytical instruments to municipal, mining, food and industrial laboratories across South Africa and the SADC region. We stock the electrodes we use ourselves. Moreover, calibration standards, filling solutions and replacement membranes are available for every model. Finally, we help you match the electrode to your meter before you order.
How do I order the dissolved oxygen probe DO-958-Q? Quote the model number and your meter. In addition, tell us which standards and filling solutions you need, and we will quote the set.
Which meter does it fit? It has a 4-pin aviation connector. The manufacturer specifies it for the 310F / 400F / 500T / 510T series meters (0 – 50 mg/L).
Is it suitable for samples with a lot of bubbles? No. The manufacturer recommends polarographic probes for bubble-free samples. For beer, carbonated beverages or aeration tanks, therefore, use an optical DO probe.
What maintenance does it need? Replace the DO-958 membrane cap and refill the electrolyte when the reading drifts or the response slows. Then recalibrate with the zero-oxygen standard and in air.
