Vee Gee  Water Activity Meter 

The Vee Gee 47002 Water Activity Meter is a portable, high-precision water activity analyzer designed for rapid and reliable measurement of free water in a wide variety of sample types including liquids, solids, and powders. Water activity is a critical quality parameter used to predict product stability, microbial growth potential, shelf life, and safety. This instrument combines simple workflow, detachable sensors, dual measurement modes, and data logging capability in a compact, field-ready unit suitable for production floors, QC labs, product development, and on-site testing.

The design allows users to prepare multiple samples at once, measure with either quick predictive mode or a full stability mode, and transfer logged data to a PC for records and further analysis; all backed by intuitive software support for setup and calibration. 

Features

Core Measurement Capabilities

• Water Activity Range: ~0.001 to 1.000 aₓ (water activity).

• Temperature Measurement Range: 0 to ~80 °C.

• Dual Measurement Modes:

  • Quick Mode for fast, preliminary results

  • Stability (Standard) Mode for fully equilibrated, precise measurements.

Sensor & Sample Flexibility

• Detachable Sensor Design: Enables preparing multiple sample cups for sequential testing while a measurement is underway.

• Capacitive Humidity Sensor: Measures solids, liquids, powders with high repeatability.

• Optional Electrical Resistance Sensor (sold separately): Better suited for samples with significant alcohol content or high volatiles.

Calibration & Accuracy

• 1- to 3-Point Calibration: Using optional calibration salts to tailor measurement accuracy across ranges.

• Accuracy: Typically ±0.01 aₓ (with proper calibration).

• Resolution: ~0.01 aₓ and 0.1 °C.

Data Logging & Connectivity

• On-board Data Logging: Stores up to ~99 measurement records.

• Logging Interval: Adjustable (e.g., 1 – 3600 s).

• USB Connectivity: Transfer data and set measurement parameters via included Windows 10/11-compatible software.

Power & Portability

• Power:

  • Four AAA alkaline batteries (not included) for portable operation

  • USB power when connected to a computer for setup and data transfer.

• Portable Form Factor: Light and compact for use in QC labs or directly on production lines.

• Protective Case: Included for transport and field use.
