Water Activity Meter EZ-201
The Water Activity Meter EZ-201 is a water activity measurement instrument developed by FREUND Corporation, Japan, designed for quality control applications requiring reliable and stable Aw measurement. The EZ-201 provides a measurement range of 0.10–0.98 Aw with a measurement precision of ±0.01 Aw at 25 ± 0.3°C. The average measurement time is approximately 10 minutes per sample.
Compared with the previous EZ-200 model, the EZ-201 features an enlarged touch panel for improved visibility and a stainless-steel lower measurement chamber, improving measurement stability and supporting more accurate measurements.
What Is Water Activity (Aw)?
Water Activity (Aw) is an important parameter used in quality control, particularly for food products and raw materials. Water activity measurement provides information about the availability of water within a product and can be used as part of quality control and product evaluation processes.
The EZ-201 measures water activity across a range of 0.10–0.98 Aw, making it suitable for measuring various types of samples.
Key Features of Water Activity Meter EZ-201
1. Wide Measurement Range
The EZ-201 measures water activity within the following range: 0.10–0.98 Aw
This allows the instrument to be used for samples with different levels of water activity.
2. High Measurement Precision and Improved Stability
The EZ-201 provides a measurement precision of: ±0.01 Aw at 25 ± 0.3°C
The lower part of the measurement chamber has been changed to stainless steel, improving measurement stability and supporting more accurate measurements.
3. Sensor Less Affected by Ethanol
The EZ-201 uses a sensor designed to be less affected by ethanol, supporting stable measurement when analyzing samples containing ethanol.
4. Enlarged Color Touch Panel
The EZ-201 is equipped with an enlarged color touch panel, providing improved visibility and intuitive operation.
The display supports English, making the instrument suitable for laboratory and quality control environments.
5. Easy Sensor Replacement and Calibration
Sensor replacement and calibration can be performed without special tools, helping simplify routine maintenance and operation.
6. Data Storage and USB CSV Output
The EZ-201 provides convenient data management functions, including:
-
- Storage of up to 100 measurement results
- Data transfer via USB memory
- CSV data output
- Measurement history and graph display
These functions support efficient recording and management of measurement results.
7. Optional Sensor Protection Filter
A sensor protection filter is available as an option to help reduce sensor deterioration caused by acid.
8. Made in Japan
The EZ-201 is manufactured in Japan and is supported by FREUND after-sales service.
What Has Been Improved from EZ-200 to EZ-201?
