mikron 81 conductivity meter

The compact detector for medium and high electrical conductivities initially at 2 µS/cm.

As a detector in the analytical laboratory or as one of the many measurement channels in SMB systems, in process chromatography and in other applications. Exact, temperature-compensated measurements of the electrical conductivity with alternating current. Two measuring cells with own measuring range to choose from.

Product advantages

small

Regardless of where you take measurements, mikron 81 is right on the spot. With a diameter of 32 mm (1.25 in.) and only 90 mm (3.55 in.) in length, it fits perfectly in every position, either fixed to the side of your system or simply on a laboratory stand.

rapid

With 10 Hz measure the dynamic course of the conductivity – no problem with mikron 81. The influence of temperature is compensated. More sensitive and precise devices exist but few which are so fast and at the same time so exact as mikron 81.

cool

A mikron 81 can be ope­ra­ted in cooled sur­roun­dings at 3 °C (37 °F).
Because of its small size it can be put com­ple­te­ly into a re­fri­ge­ra­tor. And it stays cold while being measured –
Just what you need for bio­che­mi­cal app­li­ca­tions.

bio-compatible

Only two materials are wetted: PEEK and titanium, both of which are resistant and biologically inert. In addition they are available in special qualities for use in medicine and bio technology. In this way your total process chain I documented compliantly.

open

mikron 81 speaks in many ways – on the hard­ware side via USB-C or via industry standard RS-485.
We have drivers for all current programs. More­over there is the open Runge protocol for your own im­ple­men­ta­tion.

streamlining

Both versions of mikron 81 enable flowing through up to 1,000 ml/min without any notable dynamic pressure building up.
The cell can endure a great deal – up to 150 bars (2,176 psi). Fluidic connections reach their limit sooner.
