Overview
LEICI 962223 RoHS pH Composite Electrode is a RoHS-compliant pH measurement Electrode for RoHS-compliant water sample measurement. The Electrode is made of Good Lead-Free Glass, features a high-performance ceramic core liquid junction and a long-life reference structure. It supports liquid addition operation. Dimension is φ 12 × 120mm and connector is S7.
Features
1. Compliant with RoHS standards, suitable for measurement environments with strict environmental requirements
2. Use Good Lead-Free Glass to Ensure Safety and Durability
3. High-performance ceramic core liquid junction, providing stable measurement performance
4. Long Life Reference Structure, Extend Electrode Service Life
5. Support liquid design, easy to maintain and calibrate
Principle
The pH composite Electrode works based on the principle of electrochemistry. The potential difference is generated by the selective Response of hydrogen ions to the Glass film, and a complete measurement circuit is formed by combining the reference Electrode. The high-performance ceramic core liquid interface ensures the stable diffusion of the electrolysis liquid and maintains the constant reference potential, so as to accurately measure the pH value of the solution.
Applications
RoHS compliant water sample measurement
Steps
1. Connect S7 connector to pH Meter
2. Check and add the filling solution (model 614001, 60mL)
3. Use mixing shield as needed
4. Perform calibrating (Optional accessories: calibrating liquid)
5. Electrode immersion in the sample to be tested for measurement
6. Clean after measurement and store in protective bottle (Optional accessories)
Notice
• Make sure the filling solution is sufficient before use
• Periodically calibrated for Measurement accuracy
• Avoid Electrode Glass film collision or scratch
• Electrode cleaning after measurement
• Use a liquid plug to keep the liquid junction moist during storage
• High temperature samples need to choose high temperature resistant model Electrode
