Overview

Description of Aqualab 4TE desktop high-precision water activity meter from the United States: The new generation dew point condensation mirror water activity meter (water activity meter) was officially released on September 1, 2008. Similar to the Aqualab Series 3/3TE series, this instrument uses the condensation mirror dew point technology. This means that Series 4TE/TEV not only maintains the repeatability of Series 3/3TE, but also further enhances its other functions.

American Aqualab 4TE desktop high-precision water activity metersketch:

The new generation dew point condensation mirror water activity meter (water activity meter) was officially released on September 1, 2008. Similar to the Aqualab Series 3/3TE series, this instrument uses the condensation mirror dew point technology. This means that Series 4TE/TEV not only maintains the degree and repeatability of Series 3/3TE, but also further enhances its other functions.

The user interface of Aqualab Series 4 is more user-friendly. Unlike Series 3, Series 4 replaces the sample drawer system of Series 3 with a flip cover system that is easy to operate. When the box cover is locked, the built-in O-ring will seal the sample chamber to ensure the repeatability of the results. The flip system also facilitates instrument cleaning. Cleaning the mirror, infrared sensor, and sample detection chamber can be completed without disassembly. The Aqualab Series 4 series uses the same sample cup and salt solution as the 3 series.

The new menu system is more user-friendly and suitable for user operation. The interface for new device settings, calibration, and temperature settings is very simple and convenient for users' consideration. The design of the Series 4 series includes an administrator control interface that complies with the requirements of 21CFR Part 11 (covering electronic records and electronic signatures). The menu system includes the establishment of administrators and users, and administrators can restrict the use of instruments through special settings and passwords. This allows managers to control which instrument settings are modifiable and which menus are accessible.

The storage function of the instrument has been further expanded compared to the Series 3 series, and can simultaneously record more than 10000 experimental data, including water activity, measured temperature, measurement time, operation date and other information, making it convenient for users to search for data. The data can also be transmitted to a computer for mathematical statistics through a standard RS232 interface.

Briefly describe	Aqualab 4TEThe mirror condensation dew point technique used to measure the water activity of samples（aw）It is a water activity meter that does not require daily calibration. The instrument has automatic temperature control function, short measurement time, high accuracy, and can automatically save10000A piece of data.	DUOin the presence of4TEOn the basis of all functions, moisture content indicators can also be provided, and the measurement time is less than5minHigh accuracy. The moisture content measurement adopts excellent isothermal moisture absorption technology. The built-in isothermal moisture absorption curve database, which simultaneously obtains moisture activity and moisture content indicators, is one of the effective methods for quickly measuring moisture indicators.	4TEVin the presence of4TEOn the basis of all functions, a capacitive sensor has been added. Capacitors and cold mirror dew points can be easily switched between the two.
