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.
A 4 graphite poles conductivity cell with integrated temperature probe and ISM. Designed for general applications like standard and high conductivity samples.
Wide measuring range The 4-pole cell eliminates polarization effects and guarantees a great linearity over a huge conductivity range.
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.
Origin of Precision. A micro 2 platinum poles conductivity cell with a chemical resistant glass body and integrated temperature probe. Designed for small sample volumes.
Small shaft for small samples The slim shaft diameter allows measurements of very small sample volumes.
Resist harsh and organic chemicals
A glass shaft and platinum poles assure an excellent chemical resistance.
Always the right temperature The integrated temperature probe guarantees you always measure with the right temperature compensation
