The most notable changes are the enlarged touch panel and the stainless-steel lower measurement chamber, which improve visibility and measurement stability during operation.
EZ-201: An Improved Model Based on EZ-200
In Water Activity measurement, measurement stability and ease of operation are important factors for laboratories and quality control departments.
Based on customer requests, FREUND has upgraded the EZ-200 to the EZ-201. Rather than completely redesigning the instrument, the EZ-201 focuses on improving key areas that directly affect everyday operation and measurement stability.
The two most notable improvements are:
-
- An enlarged touch panel for improved visibility.
- A stainless-steel lower measurement chamber to improve measurement stability and support more accurate measurements.
In addition, maintenance time has been reduced, making routine operation more convenient.
1. An Enlarged Touch Panel for Better Visibility
One of the most visible changes to the EZ-201 is its enlarged touch panel. This improvement was made in response to customer requests for better visibility. The larger display makes it easier for operators to view information and interact with the instrument during measurement. The EZ-201 features a color touch panel and supports English display, making it suitable for laboratory and quality control environments.
Although this may appear to be a simple design change, it can make a practical difference when the instrument is used regularly.
2. An Improved Measurement Chamber with Stainless Steel
Another important improvement is found in the measurement chamber. The lower part of the measurement chamber on the EZ-201 has been changed to stainless steel.
According to FREUND, this change improves measurement stability, supporting more accurate measurements. This is an important improvement because the measurement chamber is directly involved in the measurement process. Greater stability helps support consistent measurement performance.
FREUND notes that the stainless-steel parts are rust-resistant. However, users should avoid scratching the surface during operation and maintenance.
3. Improved Measurement Stability
The changes to the measurement chamber are not only intended to improve the physical design of the instrument.
According to FREUND, changing the lower part of the measurement chamber to stainless steel has improved measurement stability, supporting more accurate measurements. The EZ-201 provides:
-
- Measurement range: 0.10–0.98 Aw
- Measurement precision: ±0.01 Aw at 25 ± 0.3°C
- Average measurement time: approximately 10 minutes per sample
These specifications allow the EZ-201 to support Water Activity (Aw) measurement for quality control applications.
4. Reduced Maintenance Time
The EZ-201 also includes an improvement related to maintenance.The time required for Cerebration for C3 and C4 has been reduced from: 2 hours → 1 hour for each type
Reducing this time helps shorten maintenance periods and allows the instrument to return to operation more quickly. For laboratories that use the instrument regularly, this can be a practical advantage in daily operation.
5. EZ-201 Maintains the Key Features of the EZ Series
While the EZ-201 introduces several improvements, it continues to maintain the key characteristics of the EZ series. The instrument uses an electrical resistance type sensor and provides a Water Activity measurement range of 0.10–0.98 Aw. The EZ-201 also supports 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 make it easier for users to record, monitor, and manage measurement results.
6. Applications of the EZ-201
Water Activity is an important parameter in quality control for a wide range of products. According to the product information, examples of samples for the EZ-201 include:
-
- Bread and bakery products
- Cheese
- Cakes
- Dried fruits
- Meat
- Powders and powdered materials
- Jam and gel products
- Noodles
- Soybean-based products and soy sauce
The Water Activity Meter EZ-201 can therefore be used in laboratories and Quality Control departments that need to measure and monitor the Water Activity of products or raw materials.
EZ-200 vs. EZ-201: Key Improvements
| Item | EZ-200 | EZ-201 |
|---|---|---|
| Display | Touch panel | Enlarged touch panel |
| Lower Measurement Chamber | Previous design | Stainless steel |
| Measurement Stability | EZ-200 standard | Improved |
| Cerebration for C3/C4 | 2 hours each | 1 hour each |
| Maintenance | Longer maintenance time | Reduced maintenance time |
| Measurement Range | EZ-200 specification | 0.10–0.98 Aw |
| Measurement Precision | EZ-200 specification | ±0.01 Aw at 25 ± 0.3°C |
The EZ-201 can therefore be viewed as the next improvement of the EZ Water Activity Meter series, focusing on factors that directly affect operation: visibility, measurement stability, and maintenance time.
From EZ-200 to EZ-201: An Upgrade Focused on Real-World Usability
The EZ-201 is not simply a new model with a different name. FREUND's improvements focus on practical aspects of everyday instrument operation.
A larger touch panel makes operation and viewing more convenient.
A stainless-steel measurement chamber improves measurement stability.
Reduced Cerebration time from 2 hours to 1 hour helps shorten maintenance time.
Combined with a 0.10–0.98 Aw measurement range, ±0.01 Aw precision, and convenient data management functions, the EZ-201 provides an improved version of the EZ-200 platform.
