Ions in Motion Conductivity Probes

InLab conductivity probes with 2-pole cells provide the highest accuracy at low conductivity levels. Probes with 4-pole cells display a great linearity over a large conductivity range and are best suited for samples with mid to high conductivity.

Ultrapure water is extensively used for the production of microelectronics and semiconductors. Its purity must be guaranteed and regularly checked. This is exactly the application for which the InLab 741-ISM was made for.

• ISM® - Intelligent Sensor Management - All the important information is stored in the sensor and transferred automatically to the meter. An ideal support for fast and safe results
• Always the right temperature - The integrated temperature probe guarantees you always measure with the right temperature compensation.
