3-in-1 pH Electrode E-301-QC – Refillable, with Temperature Sensor
R2,300.81 incl. VAT
Refillable 3-in-1 pH electrode E-301-QC: pH glass, Ag/AgCl reference and temperature sensor in one Φ12 × 120 mm polycarbonate body. 0 – 14 pH, 5 – 60 °C, BNC(Q9) + 4-pin plugs. Replacement electrode for the PH210E pH meter.
Description
Overview
The pH electrode E-301-QC is a combination electrode with a built-in temperature sensor. In other words, it combines the pH glass bulb, an Ag/AgCl reference and a 2.25 kΩ thermistor in one unbreakable polycarbonate body (Φ12 × 120 mm). It covers 0 – 14 pH at 5 – 60 °C.
Moreover, you can refill it with 3 M KCl. As a result, you top up the reference instead of replacing the electrode. The BNC(Q9) plug carries the pH signal, and the 4-pin aviation plug carries the temperature signal for automatic temperature compensation. Finally, it is the standard electrode of the PH210E portable pH meter, and therefore also its replacement.

Applications
The electrode measures pH in drinking water and wastewater, boiler and cooling water, and pools and spas. In addition, it serves general laboratory pH measurement with automatic temperature compensation.
Why buy the pH electrode E-301-QC from Hadron Group
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.
Frequently asked questions
How do I order the pH electrode E-301-QC? 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 meters does it fit? Meters with a BNC(Q9) pH input and a 4-pin aviation temperature input. For example, it is the standard electrode of the PH210E portable pH meter.
Is it refillable? Yes. You refill the reference with 3 M KCl, which we supply in 100 mL, 250 mL or powder form.
How should I store it? Store it wet, in pH electrode storage solution or 3 M KCl. However, never store it in distilled water.
