pH
The Hydrolab pH sensor uses glass bulb and refillable reference electrode for reliable data from a sensor that is easily maintained and long-lasting.
Features:
- KCl impregnated glass bulb is permeable to hydrogen ions; reference filled with 3M KCl and has a porous Teflon junction. Salt bridge is formed between the two, and a potential is measured.
- Choice of standard or integrated refillable reference
- A special low ionic strength reference electrode is available for measuring waters with conductivities below 200 µS
- Optionally paired with ORP sensor
Benefits:
- Reference electrode is easily refilled in seconds – independent of the pH sensor
- pH sensor does not need replacement when reference electrode is depleted; simply refill the reference
