Electrodes
HI1048 Wine Must pH Electrode
At the heart of every pH measurement is the pH electrode. There are many considerations that are used when designing a pH electrode for a specific application. With wine juice and must there is a high solids content that can lead to the clogging of the reference junction. The HI1048 wine pH electrode incorporates a PTFE sleeve that repels solids and is movable to clean the interface between the sample and the reference.
- PTFE Sleeve Junction
- Double Junction design
- Refillable with 3.5M KCl
- Glass body for fast thermo-equilibrium
HI1131 Glass Body pH Electrode
The HI1131 is a standard laboratory pH electrode that is commonly used on benchtop pH meters. The glass body is a good conduction of temperature allowing the reference cell to equilibrate with temperature of the sample . The HI1131 is a refillable pH electrode.
- Glass body for fast thermo-equilibrium
- Refillable with 3.5M KCl
- Double Junction design
- Ceramic junction
HI1230 PEI Plastic Body pH electrode
The HI1230 is a rugged field pH electrode that is commonly used on portable pH meters. The chemically resistant plastic body protects protects this probe from accidental breakage. The HI1230 is gel filled so no refill solution is required.
- PEI plastic unbreakable body
- Maintenance free gel filled version
- Double Junction design
- Ceramic junction

Maintenance Solutions
pH Electrode Refill Solutions
Maintaining a proper filling solution level in a refillable pH electrode is critical to obtaining accurate and reliable pH measurements. The solution not only provides an electrical pathway to the internal reference but maintaining an ideal level ensures there is adequate head pressure to ensure flow through the junction into the sample.
- Solutions for both single and double junction electrodes
- Single junction electrodes use 3.5 M KCl with silver chloride
- Double junction electrodes use 3.5 M KCl
- Available in a variety of sizes
Cleaning Solutions
Maintaining a clean pH electrode is critical to obtaining accurate and reliable pH measurements. This especially true for Winemakers that measure pH in a grape juice sample that has a high content of solids from the skins and pulp of a crushed grape. Hanna offers specially formulated solution to clean the deposits and stains from a pH electrode.
- Specially formulated to remove wines or stains
- Available in 500 ml bottles or single use sachets
Storage Solutions
All pH electrodes will have a hydrated layer from on the surface of the glass sensing membrane. Maintaining this hydrated is important from a calibration standpoint since the mV response is different from a dry electrode as compared to a hydrated one.
- Specially formulated to keep the glass hydrated while minimizing organic growth
- Keeps junction hydrated for fast response
- Available in 230 and 500 ml bottles
