How to use
1. Identify the exact model engraved on your meter and compare it with the compatibility chart.
2. Turn off the device and carefully unscrew the depleted electrode.
3. Clean the threads and contacts of salt residues before installing the new one.
4. Screw the new electrode without forcing it, until it stops.
5. Calibrate the meter with pH 7.00 and pH 4.01 solutions, or with EC 1413 depending on the parameter.
6. Always store it with KCl storage solution, never dry or in distilled water.

Frequently asked questions
-
The electrode is the part that wears out in any pH or EC meter: it's not a fault, it's a consumable. When it dies, the device starts giving slow, unstable readings that won't calibrate. Replacing it restores the meter to like-new condition for a fraction of its price.
-
Choose based on the meter you have, not on the parameter you want to measure: that's the most common buying mistake with this range. Electrodes aren't interchangeable between models — each one fits only its own meter. Look for the number engraved on your device and use it to find the correct reference in the product page's compatibility table.
-
With normal use it lasts between one and two years. The sign that the end is near is when readings become slow or unstable and the device stops calibrating properly. Proper care makes the difference between it lasting years or just months.
-
The P700 Pro 2 has two independent electrodes, one for pH and one for EC. If the reading has gone off on both parameters, you need both replacements. If only one is failing, you just need to replace that one.
-
No. The electrodes on this page are exclusively for the previous range, the classic Pro and Pro 2. For the new generation (P160 Pro2, P110 Pro2, P50 Pro2, E50 Pro2, E60 Pro2, S300 Pro3, E300 Pro2, H600 Pro, C800 Pro and W650), our distributor doesn't sell any replacement electrode, even though those devices' product pages advertise a replaceable electrode. We're telling you this clearly so you don't buy something that won't fit.
-
The bulb of a pH electrode must never dry out. Always store it with KCl storage solution, never in distilled water or exposed to air. Letting it dry out is the most common reason an electrode dies in months instead of years.
