pH/temp. electrode, type 231, plastic/gel/temp. NTC30kOhm, BNC-plug for SD 300 / SD 305 pH (SET 1)
For water analysis in laboratories or mobile
- Dual ceramic diaphragm for fast response times even in water samples with low conductivities (≥ 100 µS/cm)
- Gel electrolyte for low-maintenance
- Integrated temperature sensor (ATC) for precise pH measurements
The SD pH electrode type 231 with gel electrolyte is not only low-maintenance, but also features fast response times. With the use of two ceramic diaphragms, measurements in water samples with low ionic conductivities are no longer a challenge. The integrated temperature sensor (NTC 30 kΩ) ensures that your pH measurement is not affected by temperature fluctuations and can be individually adapted to each sample.
The robust plastic housing made of SAN provides the necessary mechanical stability and protects the cylindrical glass membrane from breakage. The BNC connection is suitable for all pH meters equipped with a BNC socket.
