Water Quality Sensor (Flat Surface Laboratory pH Electrode) - S450C\S450CD\S450CDHF
1. The glass membrane of the flat surface pH electrode that contacts the sample is flat.
2. The pH electrode body is made of high-strength epoxy resin engineering plastic, sturdy and durable.
3. The pH electrode head comes with a soaking storage bottle containing storage solution, in which the electrode head is immersed, so it is ready to use immediately.
4. It is a combination electrode with both pH measuring and reference units.
5. The internal reference electrode is sealed, gel-filled, and performs as well as refillable reference electrodes.
6. Double junction version available: model S450CD. Use double junction when proteins contain heavy metals such as silver that precipitate. Double junction design prevents precipitation.

IV. Advantages of the Flat Surface Design of the pH Electrode：
Self-cleaning operation:
When the flat surface electrode is exposed to flowing samples, the self-cleaning effect becomes apparent. Spherical surface electrodes, due to their structure, have 'dead zones' in some areas, which over time can cause inaccurate signals and drift.
Wear-free operation:
The flat surface design reduces sample impact, greatly extending the electrode's service life. Spherical electrodes, due to frequent sample impact, are prone to calibration drift and have a short lifespan.
Operation with viscous substances:
For spherical electrodes, viscous substances easily adhere to the electrode surface, preventing fresh samples from contacting the electrode promptly, leading to reading errors. Flat surface electrodes have poor adhesion for samples, allowing timely contact with fresh samples, thus avoiding reading errors.
