pH electrodes with gel electrolyte are ideal for portable measurement but also for routine measurement in the lab. We especially recommend these pH electrodes for all applications, where reliable measured values are needed even under the most adverse conditions. The temperature compensation is set manually or with an external temperature sensor.
