pH electrode glass/gel, type 235, without temperature sensor, BNC-plug forSD 300 / SD 305 pH
- Glass housing resistant to chemicals
- Two electrolyte chambers to protect the diaphragm from clogging
The SD pH electrode type 235 with gel electrolyte is very resistant to chemicals and easier to clean due to the glass housing. The inclusion of a second electrolyte chamber makes this pH electrode less sensitive to impurities such as sulfides, which can lead to diaphragm clogging in the presence of silver ions (Ag+).
The storage bottle with rubber seal is ideal to keep the pH-sensitive glass moist even after a long storage period and to protect it from breakage. Temperature compensation is achieved either by manual input into the meter or automatically by using a SD temperature sensor.
