Overview
HI3148B is an ORP Electrode from the HANNA brand, featuring a Glass body design with a Platinum Sensor and CPS anti-clogging technology. The Electrode can be refilled with 3.5M potassium chloride electrolysis and uses a BNC connector for applications such as wine.
Features
1. Platinum Sensor: Chemically inert platinum material ensures fast electronic exchange and mechanical Stability.
2. CPS Anti-Blocking System: Using Frosted Glass and PTFE Casing to Prevent Junction and Extend Electrode Service Life.
3. Glass design: resistant to chemical corrosion, easy to clean, and quickly transfer heat to stabilize the reference potential.
4. Double junction reference: Internal compartment design to reduce silver ions entering the sample, suitable for sensitive applications.
5. Refillable function: Allows the use of HI7082 3.5M KCl filling liquid, removing the filling cap can improve the electrolysis Flow velocity and speed up the reading stability.
6. BNC connector: Universal design, compatible with any pH/mV meter with a female BNC input.
Principle
ORP Electrode detects the Oxidation-reduction potential of the sample with a Platinum Sensor, which itself is not oxidized or reduced, ensuring chemical inertness. The reference signal and Sensor signal are conducted through the Electrode body to the measurement instrument, resulting in an mV reading. The CPS technology utilizes the porosity of frosted Glass and PTFE casing to maintain electrolysis flow and prevent clogging, while the double junction design isolates silver ions and reduces interference.
Steps
1. Remove the filling cap to generate positive head pressure and increase electrolysis Flow velocity.
2. Connect the Electrode to a pH/mV meter with a BNC input.
3. Electrode immersion in the sample for measurement.
4. Wait for the reading to stabilize and record the result.
Notice
• Electrode temperature range is -5 ° C to 80 ° C, avoid using beyond this range.
• The voltage resistance is 0.1 Bar to prevent operation in high voltage environments.
• Make sure to remove the padding cap before use to optimize performance.
• Periodically check and refill 3.5M KCl electrolysis to maintain accuracy.
• Pay attention to the fragility of Glass when cleaning to avoid damage.
