±2000mV 0~80℃ ORP Electrode With Platinum Head Glass For Swimming Pool
An ORP sensor consists of an ORP electrode and a reference electrode, just like a voltmeter measures the difference in potential (voltage). The principle of ORP measurement is to use an inert metal electrode (platinum, sometimes gold) which, due to its low resistance, will either give up electrons to the oxidizing agent (chlorine in this case) or accept electrons from the reducing agent (sulfur dioxide in the dechlorination process middle).
The ORP electrode will continue to accept or give up electrons until it develops a potential, which is equal to the ORP of the solution due to the accumulation of charges. Typical ORP measurement accuracy is ±5 mV.
Please click the catalog of ORP controller here:
◆ Glass shell ORP composite electrode, divided into two basic types: ring-shaped platinum detection head and flat platinum detection head;
◆ Ring-shaped platinum has a wide response range and is suitable for sewage environment;
◆ Platinum is easier to clean and polish, suitable for water purification environment
◆ The reference adopts annular porous Teflon diaphragm;
◆ The reference electrode is Ag/AgCl, and the reference is filled with KCL colorless high temperature gel;
◆ Porous Teflon membrane has the characteristics of fast penetration speed, fast response, not easy to block, and easy to clean;
◆ A mounting thread with a size of PG13.5 is provided at the end of the electrode, which is more convenient

1. Does ORP measurement require temperature compensation?
A: ORP measurement is not temperature controlled, so the ORP sensor does not require temperature
2. How do we choose the ORP electrode when the oxidation level is high?
A: In occasions where the oxidation level is high, that is, the ORP value is high, platinum electrodes are recommended, otherwise gold electrodes are recommended. ORP measurements usually use the above two inert materials as indicator electrodes.
3. What is the wire length of the ORP electrode?
A: The lead wire of this electrode is 5m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
4. What should ORP electrodes be used with?
A: ORP electrode cannot be used alone, it must be connected with PH/ORP controller. We have a matching controller with a suitable price, and you can choose.
5: Are you trading company or manufacturer ?
A: We are a manufacturer, committed to producing high accuracy, long-term stability, cost-efficient online, portable(single-parameter and multi-parameter), water analysis instruments
