Mettler Toledo – pH electrode InLab Routine Pro-ISM (51344055)


Manufactured by Mettler Toledo

A glass-body, combination pH electrode with integrated temperature sensor, MultiPinTM head and ISM. Designed for general laboratory applications; fast and highly chemical resistant.

The extremely robust HA membrane glass is specifically designed for use at high pH values, reducing otherwise common alkali errors to a minimum.

All the important information is stored in the sensor and transferred automatically to the meter. The ideal support for fast and safe results.

The integrated temperature probe guarantees you always measure with the right temperature compensation.
