WTW pH electrodes are the most frequently used sensors in chemical labs. WTW offers these for all applications and special cases
pH electrodes with gel electrolyte are ideal for portable measurement but are also very well suited for routine measurement in the lab. The electrodes are available with and without a built-in temperature sensor. We especially recommend these pH electrodes for all applications, where reliable measured values are needed even under the most adverse conditions.
The electrodes do not require any maintenance besides occasional cleaning and are therefore especially economical.
For demanding measurements in the lab, there are SenTix® electrodes with 3 mol/l KCl liquid electrolyte, easy to clean glass shaft and platinum diagphragm. These electrodes can also be used in difficult samples. And if you need an electrode with liquid electrolyte for portable measuring: The SenTix® 51/52 with plastic shaft, integrated temperature sensor and ceramic diaphragma masters nearly every measuring task, even in the field. |
