Overview
The Mettler Toledo InLab 731 51344020 is a precision conductivity probe engineered for general laboratory applications. Featuring a 4 graphite poles conductivity cell with integrated temperature probe, it is designed for general applications like standard and high conductivity samples. The plastic body gives full protection when used in “rough handling” environments.
Key Features
- 4-pole cell eliminates polarization effects and guarantees great linearity over a huge conductivity range
- Integrated temperature probe guarantees always measuring with the right temperature compensation
- Open-tip design allows for easy rinsing and minimizes sample carryover
- Features fixed 1 m cable and epoxy shaft with integrated 30 kOhm NTC temperature sensor
- Suitable for physical, medical, microbiological, and biological laboratory environments
