The most advanced feature of this series is the electrode shape with a flat tip, virtually eliminating deposits that can foul the electrode, significantly reducing necessary maintenance. This characteristic makes flat tip electrodes ideal for continuous in-line monitoring and for solutions containing aggressive chemicals. The PVDF body offers a higher level of mechanical and temperature resistance. Moreover, the PVDF material is non-toxic and compatible with food applications. Each pH and ORP electrode is provided with an internal matching pin that can avoid typical problems caused by grounding loop current, such as: • progressive damage of the electrode • fluctuating measurements • poor process regulation Select the flat tip electrode that best fits your process requirements by choosing from the following technical characteristics: 1. Junction Three junction types are available: • Annular non-clogging PTFE junction, for testing solutions with high content of suspended solids or for high pressure installation • Open junction, ideal for wastewater analysis • Ceramic junction 2a. pH Electrodes Hanna has developed four types of specialized glass. First is a durable sensor glass for general purpose, industrial use. This glass can withstand the stress of daily use. The remaining types of electrode glass allow continuous monitoring in highly acidic solutions containing fluoride ions, as well as high or low temperature process and streams significantly increase the electrode life. 2b. ORP Electrodes ORP electrodes are provided with a platinum sensor for most applications, while a gold sensor is required for measurement of cyanide or highly oxidative environments. 3. Temperature Sensor The pH electrodes with built-in 3-wire Pt100 or Pt1000 temperature sensor allow for the temperature compensation of pH readings as well as temperature measurements. 4. Connection Type Electrodes are wired for direct connection to a transmitter or process controller, or with the standard BNC connector. 5. Built-in Amplifier Models with a built-in amplifier are necessary for long distance measurements, where it is not possible to install a transmitter. The internal amplifier can be powered directly from select Hanna process controllers or a power source that supplies the appropriate voltage. 6. Cable Length Non-amplified electrodes are provided with a 5, 10 or 15 m cable (16’, 33’ or 49’), while the amplified models are provided with a 15, 25, 50 or 75 m cable (49, 82, 164 or 246’).
