Aqua Master Tools P110 Pro Electrode - Replacement pH, EC & Temperature Probe - 3.6 x 1.2 x 1.2-in

Restore Your Combo Pen's pH, EC and Temperature Readings - 3.6 in Length

A worn or damaged probe makes nutrient solution readings unreliable, and a reservoir check is only as good as the sensor behind it. This replacement electrode fits the P110 Pro combo pen and brings back pH, EC and temperature measurement without replacing the whole meter. When attached to the meter, it is rated IP67 for water protection.

Sold as a single electrode, this unit suits any grower who already owns a P110 Pro combo pen, from a home hobbyist with one hydroponic system to an indoor operation that keeps a spare on hand so the meter stays in service.

Key Features & Benefits

• Replaceable design — swap the probe instead of buying a new meter.
• Measures pH, EC and temperature — one electrode covers the three readings used to manage nutrient solutions.
• IP67 rating when attached — the meter handles wet environments during use.
• Compact size — it measures 3.6 x 1.2 x 1.2 in and weighs 0.076 lb, so a spare stores easily.

Who Should Use Aqua Master Tools P110 Pro Electrode

Growers who own a P110 Pro combo pen and need to replace an old or damaged probe. It is a practical spare for anyone who tests nutrient solution often during vegetative growth or flowering.

Frequently Asked Questions

Q: Which meter does this electrode fit?
A: It is made for the P110 Pro combo pen. Do not assume it fits other meters.

Q: What does it measure?
A: It measures pH, EC and temperature. EC, or electrical conductivity, indicates the strength of dissolved nutrients in a solution.

Q: How do I replace the electrode?
A: Unscrew the sealing ring at the lower part of the meter and gently pull out the old electrode. Seat the new electrode with its recess in the correct position so the connectors meet, check that the rubber seal sits properly, and tighten the sealing ring firmly.

Q: Do I need to calibrate after replacing it?
A: Yes. Calibrate the meter as described in the user manual before using it. The manual and a how-to video cover the replacement steps.

Q: Is the electrode waterproof?
A: It is rated IP67 when attached to the meter. Make sure the rubber seal is seated and the sealing ring is tight.

Q: Is replacing the electrode cheaper than buying a new meter?
A: A replacement electrode lets you keep the rest of the meter in use. Compare it with the cost of a full meter before you buy.
