Water Activity Meter DWA-600
Introduction:
DWA-600 is updated model from DWA-300 it has wider measuring range, higher accuracy, takes less time to get result, can save data to PC excels true USB and can equip 1/2/3/4 sensors as requirement.
Water activity or aw , indicates the free water content when food is stable, measures the possibility of microbial proliferation.
Food formulators use water activity to predict how much moisture migration will affect their product, so that to choose suitable package and storage method to reduce the usage of antiseptics.
Features:
1. High stability.
2. Long using life in good performance without fault.
3. Better data processing program leads to more accuracy testing result.
4. Chemical resistant. The testing result keeps reliable when testing many different kinds of volatility material.
5. Imported chip inside sensor is with good stability and high accuracy. Avoid passivation.
6. It can save real-time testing value or final testing result. User can also set time to save data. All data can be transmitted to PC and saved as file/sheet.
7. It can reserve 5000 sets of testing results, and results can be saved to PC.
8. No need to calibrate every time.
9. It has RS232 port and USB port, can be connected to mini-printer.
10. Reasonable interface, easy to operate.
11. It is suitable to test different kinds of material, such as solid, liquid, powder are all OK.
12. Optional stylus printer, can print data for long time storage.
13. The shortest measuring time is 4-5 minutes only.
14. Buzzing when measurement finishes or calibration finished.

High-Throughput, Precision Water Activity Analysis: Water Activity Meter DWA-600
Maximize lab efficiency without sacrificing accuracy with the Water Activity Meter DWA-600—a premium, multi-sample benchtop instrument engineered for food science, pharmaceuticals, cosmetics, and agricultural research. Capable of measuring water activity (aw) from 0.00 to 1.00 aw with ±0.001 aw accuracy, the DWA-600 supports simultaneous testing of up to 6 samples, making it ideal for R&D, quality control, and compliance labs requiring high-volume, regulatory-grade results.
Engineered for Speed, Precision, and Scalable Workflow
The DWA-600 Water Activity Meter features six independent, temperature-controlled measurement chambers, each equipped with a high-stability capacitive sensor and active airflow for rapid equilibration. All chambers maintain 25°C ±0.1°C—in compliance with ISO 21807, AOAC, and USP <1151>—ensuring lab-to-lab reproducibility. Advanced algorithms auto-detect equilibrium, delivering reliable results in 3–8 minutes per batch.
- Ultra-High Accuracy: ±0.001 aw | Resolution: 0.0001 aw – Suitable for pharmaceutical APIs, lyophilized products, and sensitive food matrices.
- 6-Channel Simultaneous Testing – Process 6 samples in the time it takes single-channel meters to test one.
- Precision Temperature Control: 25°C ±0.1°C Across All Chambers – Ensures method compliance and data integrity.
- Large Touchscreen with Batch Management – Assign sample IDs, track runs, and view real-time aw curves for all channels.
- Full GLP/GMP Compliance – Stores 5,000+ records with user ID, calibration data, and audit trail; USB, Ethernet, and optional 21 CFR Part 11 support.
- Reusable Sample Cups & Auto-Diagnostic Sensors – Low operating cost with sensor health monitoring for proactive maintenance.
Trusted in Regulated and High-Performance Laboratories
From validating moisture stability in biologics and nutraceuticals to optimizing texture in confectionery or preventing caking in powdered detergents, the DWA-600 delivers the throughput and precision modern labs demand. Its ability to generate publication- or submission-ready data makes it a cornerstone in ISO 17025, GMP, and HACCP environments.
Whether you’re running stability studies, batch release testing, or formulation trials, the Water Activity Meter DWA-600 transforms water activity from a bottleneck into a strategic advantage.
