Precision Instrument for Shelf-Life Determination in Food, Pharmaceutical, Cosmetic, and Herbal Industries

The aWLife Water Activity Meter is a high-performance analytical instrument designed for precise and rapid determination of water activity (aW), a critical parameter in assessing shelf life, microbial stability, and product quality. Entirely developed and manufactured in Italy by Steroglass, aWLife represents the state of the art in water activity measurement and has become an indispensable tool for quality control in the food, pharmaceutical, cosmetic, herbal, and pet food sectors.

Key Features and Benefits

Fast and Accurate Measurement

Measurement time: < 5 minutes at equilibrium
Accuracy: ± 0.003 aW at 25°C (± 1°C)
Ensures repeatable and reliable results across a wide range of sample types

Dew Point Sensor Technology

Utilises a dew point sensor to measure true free water activity (aW), not secondary or proxy parameters.
Measurement is based on the thermal equilibrium between the liquid water phase in the sample and the vapour phase in the headspace.
Complies with ISO 18787:2017, ensuring global regulatory acceptance.

Touchscreen Graphic Interface

Features a 7” colour touchscreen display for intuitive navigation and operation.
Allows direct interaction with functions, calibration settings, and data export options.
Compatible with USB and Wi-Fi, enabling easy integration with PCs and external printers.
Includes automatic data storage, sample identification, and operator tracking.

Precise Temperature Control

Thermostated sample chamber with a temperature range of 15°C to 50°C.
Programmable settings ensure consistent test conditions during shelf-life studies and stability testing.

Single or Multi-Point Calibration

Supports both single-point and multi-point calibration using standard references.
Multi-point calibration ensures precise adjustment of the calibration curve for improved measurement accuracy.

Sensor and Chamber Design

The sensor block features a front-opening chamber for easy sample placement and cleaning.
Integrated fan system ensures homogeneous temperature and humidity distribution.
Highly sealed chamber prevents environmental interference and cross-contamination.

Applications and Use Cases

The aWLife meter is designed to address a wide range of applications where water activity plays a critical role in shelf-life determination, regulatory compliance, and product development.

Suitable for:

Food Products (moisture-sensitive goods, dry snacks, dairy, meats)
Pharmaceutical Formulations (powders, capsules, tablets)
Cosmetic Products (creams, lotions, gels)
Herbal Preparations (extracts, essential oils)
Pet Food (wet and dry formulations)
