MicroDens Logger Pro

Features

Reading acquisition and management

MicroDens readings are collected in separate sessions, one per batch or per check, with statistics, evaluation against tolerance and reports. No value is copied by hand from the display. Logger Pro is intended for quality control and production laboratories, wineries and breweries.

Sessions and archive

In History, each session can be searched by batch, product or operator and exported to Excel, PDF or CSV.

Three chart types

Time Series, with target and limits, for the trend of a process; Grouped, with one bar per batch and the standard deviation; Overlay, for several samples on the same axes.

27 predefined methods

Each method sets the data model, statistics, chart and QC evaluation: setup is immediate and every function of the program is available from the first session.

Batch comparison

The current batch can be compared with up to five batches of the same method: overlaid curves, with the mean and standard deviation of each.

Advanced features

Lab analyses

Results of other analyses, from an in-house or outside laboratory, are recorded in the session; the main value appears on the chart on its own axis, and all results are included in the report.

Chart annotations

Events and observations are annotated on the chart as a note, marker or phase, with the author's name, and are carried into the report.

Multi-instrument management

Each MicroDens is registered by its serial number and a user-assigned name. Instruments connect one at a time; each reading keeps the serial number.

Sample IDs from the PC

Logger Pro sends the next sample ID to the instrument, fixed or incremental, so the operator does not have to type it.

Program screens

Quality control

Tolerances, statistics and batch comparison

A target and a tolerance are set for each session. Logger Pro evaluates each reading, each sample or the whole batch and shows the result: OK or out of specification (OOS).

Statistics have three levels: basic (number of readings, mean, standard deviation, minimum and maximum), extended (median, percentiles, coefficient of variation) and process control (Cp, Cpk, control limits).

In Session Comparison the current batch is shown beside up to five batches of the same method, with overlaid curves, the mean and standard deviation of each, and the difference from the overall mean.

Fermentation module

Wine and beer fermentation

Fermentation is a paid add-on module for Logger Pro: a single license covers both wine and beer fermentation. It is included in the 30-day free trial.

During alcoholic fermentation, density decreases as sugars are converted into alcohol. Measured at intervals on the same tank or fermenter, density describes the course of fermentation: its curve shows when fermentation starts, when it slows down and when it approaches the end. Logger Pro plots each MicroDens reading on the curve and derives phase, status and estimated end. For wine the reference scale is °Brix, for beer degrees Plato (°P).

Wine · °Brix

Alcoholic fermentation and prise de mousse

One session per tank, with phases, gravity thresholds, lab analyses and enological event log; a linked prise de mousse session starts from the alcoholic fermentation, with the pied de cuve doublings.

Wine fermentation

Beer · °P

Extract, attenuation and final gravity

One session per fermenter, with apparent extract, apparent and real attenuation, estimated ABV and final gravity (FG) projection.

Beer fermentation

Wine

Wine fermentation

Every tank followed in real time

Each MicroDens Wine Must reading adds a point to the tank curve and updates phase, residual sugars and status. The module covers alcoholic fermentation (FA) and prise de mousse.

The Sessions page brings the tanks together, each with its curve, last reading and status. The PDF tank report includes charts, thresholds, the enological event log and lab analyses; the Excel file contains the fermentation summary, the event log and the lab analyses.

MicroDens Logger Pro, Sessions page: ten tanks in alcoholic fermentation, each with its curve, °Brix, °Babo, residual sugars, ABV, estimated end and status — Sessions page: ten tanks in FA, each with its curve, last reading and status.

Infographic: on the left, °Brix of four tanks in alcoholic fermentation, with the lag, active fermentation, slowing and end phases and the FA end threshold; on the right, prise de mousse, with the pied de cuve doublings, the transfer to the autoclave and the end of prise de mousse threshold — Left, °Brix during alcoholic fermentation, with the phases marked by Logger Pro; right, prise de mousse: the pied de cuve is built up by successive doublings and then incorporated into the base wine in the autoclave. Demonstration data.

Tank management

Sessions can also be created in bulk, up to fifty at a time. If the MicroDens sample ID matches the tank name, the Wine Must reading enters that tank's session.

Curve and phases

°Brix, °Babo, SG at 20 °C and temperature at every reading. The chart distinguishes lag, active fermentation, slowing and end of FA; a gravity threshold signals the nutrient addition.

Lab analyses

Residual sugars, malic acid, SO₂ and pH, from an in-house or outside laboratory, are recorded in the session. Sugars and real ABV are shown on the curve, the other values on a dedicated chart; real ABV replaces the estimate.

Tank comparison

A tank can be compared with other tanks or earlier fermentations: curves aligned from the start, starting gravity, ABV and duration. Up to five sessions besides the current one.

Prise de mousse

A linked prise de mousse session opens from the FA, with the base wine SG. Each pied de cuve doubling is flagged and counted; other thresholds indicate the transfer to the autoclave and the end of prise de mousse.

Thresholds and end estimate

Gravity thresholds are set for each session, also relative to the starting gravity, and the FA end estimate is calculated from the last five readings. Actions confirmed at the thresholds are recorded in the enological event log.

Beer

Beer fermentation

Every fermenter followed in real time

Each MicroDens BeerQuick reading adds a point to the fermenter curve and updates extract in °Plato, attenuation, phase and status.

The reading also carries the original gravity of the wort (OG), which Logger Pro uses to assign it to the fermenter. The Sessions page brings the fermenters together, each with its curve, last reading and status.

Illustration: the MicroDens measures 5.2 °P in fermenter F-05 with the Detected status, and the reading appears on the MicroDens Logger Pro Sessions page, with ten fermenters — Illustration: the reading of fermenter F-05 and the Sessions page with ten fermenters.

Infographic: apparent extract in °P of four fermenters over days, with the lag, active fermentation, slowing and end phases — Apparent extract in °P of four fermenters, with the phases marked by Logger Pro. Demonstration data.

Logger Pro follows beer fermentation on the apparent extract, in °P, from the OG of the wort to the final gravity (FG).

FG projection

From the curve of a batch saved as a reference, or from the trend of the last 24 hours, Logger Pro estimates the final gravity (FG) and the remaining time, with a confidence rating.

Fermenter management

Each BeerQuick reading carries the OG of the wort, and Logger Pro assigns it to the fermenter with the same OG; if two batches match, the operator selects which one.

Extract and attenuation

Each reading provides apparent extract in °P, apparent and real attenuation, estimated ABV and temperature. The curve indicates lag, active fermentation, slowing and end.

Lab analyses

pH, acidity, color in EBC and bitterness in IBU, determined in the brewery or by an outside laboratory, are recorded in the batch session. The pH is shown on the curve.

Batch comparison

The fermenting batch can be compared with earlier batches: curves aligned from the start, with OG, attenuation, ABV and duration of each. Up to five batches besides the current one.

Import from memory

Readings stored in the instrument memory (History) are imported in bulk and assigned to the open sessions by sample ID, after a review that excludes duplicates. The transfer is started from the instrument.

Archive and backup

Sessions stay on the PC. A scheduled backup saves the archive to a local folder and, if configured, to a server, where reports can also be sent automatically after each export.
