The pH electrode InLab® Expert NTC30 from Mettler-Toledo has a shaft in PEEK plastic, built-in temperature probe, and a MultiPin™ plug head. The sensor is developed for general use in laboratories and in the field, with a special focus on robustness and minimal maintenance. Ideal for a wide range of applications, including emulsions, suspensions, water water, and solutions containing proteins and sulfides. With polymer electrolyte for use whitout refill. Shipped without cable.

The InLab® Expert electrodes have been designed with long life and ease of use in mind.
The fine-pored ceramic junction used in conventional electrodes can easily become contaminated in critical media such as suspensions and wastewater. In contrast the InLab® Expert electrode with a solid polymeric electrolyte requires no junction at all. As a result these sensors are particularly insensitive to contamination.
In addition, the high grade plastic (PEEK) shaft offers a high level of chemical resistance and robustness. Service life and measurement accuracy are further improved by the ARGENTHAL™ reference system which reduces loss of silver chloride from the reference wire at differing sample temperatures.
