Aqua Master Tools Probe Holder - 12mm Electrode - 1/2-in Male Thread

Inline Electrode Mounting Without Extra Plumbing - 12mm

Reading pH, EC or Redox in a running line is hard when the electrode has nowhere secure to sit. This holder seats a standard electrode directly in the pipeline, so you can measure the water as it flows instead of sampling by hand. It is built for use with a 1/2 tapping saddle, which keeps the install simple.

Sold individually, this holder suits a grower adding one monitoring point to a hydroponic system or irrigation line. Growers who monitor several points can order one for each.

Key Features & Benefits

• Fits standard 12mm electrodes — works with pH, EC and Redox electrodes of that size.
• 1/2-in male thread — screws into a matching 1/2 tapping saddle.
• Inline measurement — reads the line directly without complex plumbing.
• Nylon and EPDM construction — a durable body with an elastomer seal component.

Who Should Use Aqua Master Tools Probe Holder

Anyone running irrigation, hydroponic or water treatment lines who wants continuous electrode readings. It suits home gardeners and commercial operations alike, provided the line has or can take a 1/2 tapping saddle.

Frequently Asked Questions

Q: Which electrodes does it hold?
A: It holds standard 12mm electrodes, including pH, EC and Redox types. Check your electrode body diameter before ordering.

Q: Can I fit it into any fitting?
A: No. It fits only 1/2 tapping saddles. Other fittings are not supported.

Q: What is a tapping saddle?
A: A tapping saddle is a clamp-on fitting that attaches to a pipe and provides a threaded port. It lets you add a connection point without cutting the line.

Q: Why measure inline instead of in a bucket?
A: Inline measurement reads the water as it moves through the system. This avoids repeated sampling and gives a more direct view of the line.

Q: Does it include an electrode?
A: No. The listing covers the holder only, so you supply your own 12mm electrode.
