HM Digital pH Electrode Storage Solution - 60 cc

Keep Your pH Probe Moist and Ready - 60 cc Bottle

A pH probe that dries out reads slowly and wears out early. This KCl-based storage solution keeps the sensor wet between uses, and it contains a fungicide to help keep the probe clean. Refill the meter cap whenever it runs dry so the probe stays ready for hydroponic and soil-based nutrient checks.

The 60 cc bottle suits home gardeners and small indoor setups with one or two meters. Commercial growers can keep one as a spare at each monitoring station.

Key Features & Benefits

• Specially formulated KCl solution — keeps the electrode sensor in a suitable storage medium.
• Fungicide included — helps keep the probe clean.
• Twist-off and eyedropper cap — lets you pour or dose a few drops into the meter cap.
• Broad compatibility — made for the HM Digital PH-200 and PH-80 and usable with other brands of pH meters.
• Compact 60 cc size — easy to store with your meter.

Who Should Use HM Digital pH Electrode Storage Solution

Anyone who owns a pH meter and wants longer probe life: hobby gardeners, hydroponic system operators and commercial cultivation teams who check nutrient solution pH regularly.

Frequently Asked Questions

Q: Can I use this to calibrate my pH meter?
A: No. This product is not for calibration. To calibrate your meter, use a pH buffer solution.

Q: How do I use it?
A: If the meter cap is dry, refill it with the storage solution. The sponge in the cap should be moist, not soaking wet.

Q: Does it work with meters other than HM Digital?
A: It is made for the HM Digital PH-200 and PH-80 and is also intended for other brands of pH meters. Check your meter manual for its storage requirements.

Q: Why not store the probe in plain water?
A: A storage solution is made for electrode storage, while plain water is not. Keeping the sensor in storage solution is the recommended practice for pH probes.

Q: What is a KCl solution?
A: KCl is potassium chloride, a salt solution commonly used to keep pH electrodes hydrated and in good condition between uses.
