Micromac-Smart

Micromac-Smart is a portable analyser for rapid and accurate field water analysis.

µMAC-Smart è un Portable analyser fully controlled by a complete industrial PC with a colour “touch” display, specifically designed for the on-site monitoring of all types of water resources.

µMAC-Smart is robust and reliableThe analyser is housed in a robust and compact plastic case, easy to transport and complete with space for liquid reagents and other accessories. A dedicated holder keeps the reagent bottles and other solutions in place.

The analyser is easy to install and it is designed for ease of use, after a short training course. It is shipped from the factory fully tested using the required methods and ready for use; stabilised liquid reagent kits are available for standard methods. Results are stored within the instrument's memory and can be downloaded via the USB port.

Getting the instrument up and running has never been easier! Simply switch on the instrument, insert the reagent and other solution dip tubes into their corresponding bottles, and user-friendly software will guide you through the few steps necessary to perform automated analyses.

Micromac-Smart - Portable analyser for water analysis in the field

Automatic calibrations

The analyser's calibration is fully automatic; you only need to use the solution specified in the manual and start the calibration cycle. The new calibration factor is verified against the previously stored one according to pre-settable limits and is then automatically updated.

Multivariate analysis

The analyser can be configured at the factory to perform sequential multiparametric analyses on the same sample; the standard multiparametric configurations are detailed below.

Multiple analyses

The analyser allows multiple analyses to be carried out continuously; the operator selects the methods to be used and starts the automatic sample analysis, even in flow, with a selectable measurement interval.

Automatic out-of-range analysis

The analyser recognises out-of-range analyses and re-analyses the sample using automatic dilution, the dilution factor is predetermined at the factory.

Optional sampler

The analyser can be optionally fitted with a portable sampler, which allows for the automatic measurement of up to 8 previously collected samples.
