introducing vali::tool

Automatic Data Validation

Data validation and correction

The s::can be vali::tool automatically detects, marks and (optionally) corrects untrustworthy data, not by using mean average – it identifies outliers, noise and checks for discontinuous data. It ensures only high-quality data is immediately relayed to the event detection module.


Automatic data validation from vali::tool makes sure that only unmarked, “clean” data is used for further analysis, training and alarms. Any non-event-related or simply deviating data must be identified and marked before feeding them into the following event detection module.

Raw data to valid data

Vali::tool is another software option available from s::can that is aimed at managing data so you don’t have to.  Vali::tool is an advanced data handling piece of software that has the capability to interpret data over time and reduce false alarms. It continuously measures the noise of the system and picks out any outliers in real time, all the conditions for doing this are completely customisable for your application.  
It is best used in conjunction with ana::tool, enabling real-time validation of data to be fed into the event detection software.



Provides self-adaptive, self-controlled data validation in real time.


Ensures both sensitive and reliable alarm limits respectively set points for process control.

Early detection

Analyses noise, outliers and other combinations in real time to reliably detect any malfunction at an early stage.


Considers user interventions in real-time.


Application-specific training period considers normal fluctuations of individual water matrix and typical process dynamics.

Reduces false alarms

Helps to dramatically reduce false alarm rates.

Auto correction

­Configurable auto-correction of data based on threshold, outlier and noise analysis.

Other software tools available with your s::can instrumentation


The moni::tool allows for easy management of operations such as cleaning cycles and measurement intervals and visualises the results to show them over time or even as 3D spectra when used in conjunction with the spectro::lyser sensor.


Identifies unknown and unusual conditions and triggers an alarm.

Every s::can con::cube terminal is delivered with the basic moni::tool version for four parameters at no extra cost.

Intelligent. Optical. OnLine.

moni::tool is a revolutionary new platform for the management of an almost unlimited number of stations, online probes, analyzers and parameters. Intuitive operation – on site or remote – and reams of valuable features make moni::tool essential for state of the art sensor and station management.

moni::app now brings moni::tool to your Smartphone! Download it today from the Google Play Store.

Introducing moni::app

moni::app is an Android app for moni::tool. It gives you a quick overview of the current system state of your monitoring station and allows you to analyze historic data. The app is limited to displaying data, it is not possible to change any settings of moni::tool.

See the complete s::can range

The s::can range measures a wide range of parameters in numerous applications. All s::can measuring instruments are developed with the same philosophy in mind: They are intelligent, robust and require little to no maintenance.

Intelligent. Optical. OnLine.

The s::can spectrometer probes from PMA Ltd operate using the same measuring principle: Spectrometry. The spectrometer probes are the first and only instruments in the world that can measure optical spectra from 190 to 720 nm directly in liquid media. The materials contained in the medium deteriorate a light beam emanated by a lamp that transfers through the liquid. After contact, its intensity is measured by a sensor over a variety of wavelengths specific to the application.
