Julian: There are some key features that make the design of this new range of digital pH sensors a big development on previous pH sensor iterations. They have been designed from the ground up building on 70 years of ABB pH knowledge.
It has customarily been a complex challenge to select the correct pH sensor for a given application. The wealth of choice available ensured accuracy, however it made selecting the correct sensor for the job particularly challenging.
Selecting the correct pH sensor glassware for the process is crucial to ensure a fast and accurate measurement. ABB unique application driven glassware formulations have been designed to provide the highest reliability and most accurate measurement in the harshest of processes. From high performance glassware to HF/Acid resistant glassware, the simplification of selection criteria has made this a much easier task.
The temperature of the process medium is an integral part of determining an accurate pH measurement as the temperature has a direct bearing on the pH reading. With the new design of the digital pH sensors is has been possible to position the temperature sensor in close proximity of the pH and reference electrodes (thermal hotspot) with response times now being 60% faster.
The digital pH range ensures it is much easier to select the correct sensor for the job by grouping them by use. There are 5 colour coded choices of sensor available in the range which covers the demands of high purity applications to harsh environments.
The digital pH range are EZlink enabled making them plug and play with brilliant connectivity and immune from issues sometimes associated with high impedance cables used with analogue pH sensors. The Sensor integration is fast and easy with installation taking just a few minutes.
The other key benefit is their reliability with two new advanced diagnostics features that ensure that reliability.
