aWLife Water Activity Meter

The aWLife water activity meter from Steroglass is a high-precision analytical instrument designed to measure the water activity (aW) of solid, semi-solid, and liquid samples. Water activity is a key parameter for determining product safety, quality, and shelf life because it quantifies the amount of free (unbound) water available for chemical and microbial activity. Accurate aW measurement helps predict the risk of microbial growth, improve formulation stability, and ensure regulatory compliance in quality control and R&D environments.

Purpose

The aWLife meter is primarily used to:

  • Determine product shelf life and stability by measuring water activity to predict the potential for microbial growth over time.

  • Support quality control programs in manufacturing and laboratory settings.

  • Optimize formulation and packaging in product development.

  • Comply with industry standards and regulatory testing workflows.

Industries

The aWLife meter is suitable for a wide range of industries where controlling water activity is critical:

  • Food & Beverage – bakery, snacks, dairy, meat, confectionery.

  • Pharmaceuticals – ensuring product stability and safety.

  • Cosmetics – stability and formulation testing.

  • Herbal & Phytotherapeutics – product quality control.

  • Pet Food – safety and shelf life testing.

Key Features

  • Dew Point Sensor Technology – Measures true water activity by detecting the temperature at which condensation forms on a chilled mirror, providing highly accurate and reliable results in compliance with ISO 18787:2017 standards
  • Fast Measurements – Typical analysis time of < 5 minutes for equilibrium water activity.
  • High Accuracy & Precision – ± 0.003 aW accuracy at 25 °C with repeatability ± 0.001 aW.
  • 7″ Colour Touchscreen Display – Intuitive graphical interface with easy workflow control, built-in menus and prompts.
  • Temperature Control – Programmable sample thermostating from 15 °C to 50 °C for consistent and comparable results.
  • Flexible Calibration – Supports single-point or multi-point calibration using standards for precise calibration curves.
  • Connectivity & Data Management – USB ports, Wi-Fi/ethernet (Industry 4.0 compatible), and export/data logging features support PC integration and reporting.
  • Security & Compliance – User access management and password protection compliant with data integrity expectations (e.g., 21 CFR Part 11).
