Runge mikron – small detector, big advantage.
1:1

small and dynamic
No matter where you want to measure: the mikron is rightthere. With a diameter of 32 mm and a length of only 90 to165 mm, it fits perfectly into any installation, mounted on
the side of your system or simply on a laboratory stand.
Measuring the dynamic course of conductivity at 100 Hz –no problem with the mikron 81. Or measure the absorption
at two wavelengths simultaneously at 100 Hz – the mikron 31 does it easily.

coolThe mikron can be operated in refrigerated environments
at 3 °C. With its small size, you can put it completely in therefrigerator, without any external cell with fibre optics.
And it stays cool during the measurement – the mikron
81 for conductivity anyway, the photometer mikron 31 too
thanks to LED technology.
Just what you need for biochemical measurements.

biocompatible
For your application in medical and biotechnology, all measuring cells are available in PEEK or titanium, both chemically resistant and biologically inert.
The wetted materials are available in special qualities onrequest (PEEK with FDA certificate, USP Class VI, prionfree, titanium as ELI).
Your entire process remains compliant with regulations.

versatile
We offer a wide range of measuring cells – three cell geometries in three different materials for photometry, two electrical cell constants for conductivity.
There are two different interfaces for all detectors in themikron family. And for the light sources, every wavelength
available as an LED.
No wish of yours remains unfulfilled, we hope.

open
The mikron 81 talks in many ways, on the hardware side
via USB or via the industry standard RS-485 with a robust
round plug.
In addition to drivers for all common applications (Clarity, SCPA ChromStar, PrepCon, NI LabView)* there is theopen Runge protocol for your own implementation.
You can start right away.
