Benefits

Multi-Probe Operation

Users can select and display up to three measurement parameters at the same time. The graphic display shows the stabilization of measurement and process trends. The MI70 indicator has two cable ports by which a combination of any two probes (or transmitters) can be connected to it simultaneously. For example, a humidity and temperature probe could be connected to one port and a CO2 probe to the other. The indicator can display the measurements made by both probes, so humidity, temperature, and CO2 data could be displayed simultaneously.

Intuitive User Interface

MI70 features a multilingual, menu-based user interface and a clear graphical LCD display. All in all three measurement parameters can be displayed and simultaneously logged in the memory. The display shows measurement trends graphically and numerically. Users can select the measurement parameters and units. MI70’s intuitive user interface operates with menus and keypads to change settings, logging, and display preferences.

Multiple Language Options

There are nine language options in MI70: Chinese, English, Finnish, French, German, Japanese, Russian, Spanish, and Swedish.

Optional Connection to PC

The optional MI70 Link Windowsâ software and the USB connection cable form a practical tool for transferring logged data as well as real-time measurement data from the MI70 to a PC
