SQC in the Laboratory: Precision Through Smart Statistical Control

Why Statistical Quality Control Matters

In modern laboratories, where accuracy and traceability are critical, single measurements are no longer enough. It is the analysis of a complete series of measurements that provides true insight into weighing reliability. RADWAG addresses this challenge through the SQC (Statistical Quality Control) module, transforming precision weighing into a data-driven process.

This solution is particularly important for labs operating in real-time feedback loops with production departments, where fast detection of deviations is essential.

Two Powerful Modules for Laboratory Statistics

RADWAG software offers two distinct statistical modules to meet diverse lab needs:

1. Statistics Module:

   • Performs operations on freely selected datasets.

   • Provides: sum, mean, min/max, range, standard deviation, and variance.

   • Allows adding new measurements to existing series (OPEN formula).

   • Ideal for general-purpose data analysis.

2. SQC Module (Statistical Quality Control):

   • Focused on mass control of samples with specified tolerances.

   • Identifies series by batch number and measurement count.

   • Does not allow adding new data after test series is complete (CLOSE formula).

   • Displays weight changes via a bar graph (SQC-GRAPH), supporting rapid visual feedback during sampling.

Advanced SQC Features

The SQC module introduces several intelligent features tailored for demanding environments:

• Tolerance-based filtration of data.

• Real-time result visualization in the Info workspace.

• Customization of:

  • Measurement quantity

  • Sample ID

  • Printouts and reports

• Record modes:

  • Manual

  • Automatic

  • Triggered by stability, or threshold values

• Precise Weighing Mode for advanced signal filtering and noise resistance.

Intuitive Interfaces and Visual Tools

With its touchscreen interface, RADWAG offers fully configurable panels for test setup, execution, and data review. The SQC-GRAPH enables users to:

• Auto-adjust tolerance bars

• Zoom and reposition charts with a finger

• Instantly evaluate sample compliance

All statistical outputs can be stored in the balance’s memory, printed, or exported for traceability and regulatory compliance (e.g., ISO, GLP, GMP, HACCP).

Seamless Data Handling and Reporting

The system generates complete reports with:

• Batch number

• Statistical results

• Graphs and metadata

Reports can be:

• Exported via USB, RS232, Ethernet or Wi-Fi

• Saved in formats like PDF, Excel (XLS/XLSX), CSV, TXT

• Shared with external systems for audit, quality assurance, or production control

SQC data is also saved in ALIBI MEMORY—ensuring secure archiving and compliance.

Automation for Continuous Measurement

RADWAG supports automated measurement cycles using:

• PA-04/H automatic feeder: Aligns and dispenses samples one by one

• RADWAG balances: Measure and record data in sync with the feeder

This configuration supports accurate high-throughput control while minimizing operator input and error.

Feeder specs:

• Object diameter: 3–10 mm

• Feeder speed: 1–15 pcs/min

Software Ecosystem: R-Lab & RadKey

RADWAG complements its balances with powerful software:

R-Lab:

• Central hub for measurement analysis from up to 20 instruments

• Graph types: line, histogram, Gaussian, stability, and composite

• Report generation, filtering, and export

RadKey:

• Lightweight tool to:

  • Capture measurement data

  • Export to any editor (TXT, DOC, XLS, RTF)

  • Use hotkeys for fast recording

  • Support multilingual interfaces

Precision with Every Click: R2 Series

The R2 series balances combine reliability and statistical functionality:

• LCD display with text info line

• Multi-function keypad with quick access to:

  • Product selection

  • Tare management

  • Header/footer customization

Capable of:

• Weighing

• Counting

• Density determination

• Statistics

• Checkweighing

• Dosing

• Peak hold, and more

Integrated Control for Modern Labs

RADWAG’s SQC solution empowers laboratories to:

• Standardize weighing control

• Streamline reporting

• Visualize data at every stage

• Ensure compliance with quality and safety standards

With automated workflows, intuitive interfaces, and powerful statistical tools, SQC by RADWAG is redefining laboratory weighing precision in 2025.
