Here are some of the benefits of using EDT direction Combination Ion Selective Electrodes:
- Rugged Solid State Sensors
- No Filling solutions
- No membrane replacements
- Built in dry Reference electrode
- Waterproof and submersible
- Suitable for Laboratory and Field work
- Compatible with all pH and Ion Meters
- Stored dry for long lifetime
- Low cost
- Easy to use
The Cadmium Sensor is a crystalline material which can be polished when the slope decreases over its lifetime. This will rejuvenate the sensor and give a longer useful life. Store the sensor dry with its protective cap in place.
Each EDT directION Combination ISE has a 1 metre cable and a BNC connector (other connectors available on request) allowing use on all types of pH/ION meter including laboratory bench and research models. For direct concentration reading and absolute simplicity the EDT QP459 pH/ION meter is the perfect instrument for these ISEs.
For Quick Ion analysis for under £500 use our ION Concentration Calculator (mV Meter Required).
The solid state sensors have a huge advantage over conventional ISEs in that there is no internal fill solution to degenerate the sensor this means that EDT direction combination ISEs have an unrivalled lifetime and a very low cost of ownership.
EDT are a UK based manufacturer and produce ISEs for many prominent companies in the water testing sector. As a result our ISEs are very competitively priced and come complete with technical support provided from our vast library of applications and our in house electrochemistry technicians.
For optimum results use EDT direction standards and Ionic Strength Adjustment Buffers ( ISABs). Click here to see a simple calibration procedure or learn more about the principles of ISE measurement.
