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
Connection Type
Electrodes are wired for direct connection to a transmitter or process controller, or with the standard BNC connector.
Glass Sensor
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.
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.
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.
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’).
