JUMO glass pH electrodes
Brief description
Glass pH electrodes are used in conjunction with reference electrodes to record the pH value.
The sensor part of the glass pH electrode is made from a special, pH-sensitive membrane glass.
Electrodes with special types of membrane glass are available for measuring in the different me-
dia:
• UW glass for general, aqueous media
• C glass for media containing fluorides (up to 1000 mg HF/l)
• HT glass for use at temperature ranges >80 °C and in highly alkaline media
