High Efficiency

The instrument is featured with high efficiency and automatic design of structure, which minimize the human operation in measuring process. Intelligent controlling and data processing functions make it easy and reliable for test operation and data processing.

• Parameter program function enables the user to save all test parameters in a file so that those parameters can be applied directly for the same tests next time, which can help the user save time and minimize the error when inputting parameters manually.
• Test results include maximum value, minimum value, average value and standard variation, which can be displayed to the user directly.
• Result comparison function can help the user in evaluation of results.
• Auto sampling function (optional), feeding space, feeding speed, measure points can be set as required, which ensures the accuracy of multiple successive points measurement.

Intelligent

The instrument is embedded with Labthinks latest operating software, which is featured with user-friendly interface, intelligent data processing, strict user management and secure data storage. It also supports Labthink exclusive DataShieldTM (Optional) which provides the users with safe and reliable management of test data and test reports.

• Test data can be displayed in various forms including curves and data list
• Test data will be saved and encrypted in a unique way so that all the test information will be saved securely and reliably and protected from being tampered
• Various forms of test data can be searched, exported and printed out

Note: The described features should be in line with Table 1: Test Parameters.
Note1: The Repeatability refers to the repeatability within the test range.

Test Principle

The pre-conditioned specimen is placed on a flat test plane, the pressure foot which is paralleled to the test plane will drop down on the upper surface of the specimen with certain pressure applied on. The displacement sensor with the pressure foot will detect the space between the upper and lower surface of the specimen, which is the thickness of the specimen.

Precision Sensor Technology

Equipped with a high-precision displacement sensor, the Labthink C640 delivers exceptional measuring accuracy down to 1 m. This sensitive detection technology is ideal for industrial laboratories that require exact panel thickness data for quality control. The system's fast response time and real-time LCD display ensure immediate feedback during testing, reducing downtime and operator error.


Automated Calibration and User Interface

The C640 features automatic calibration, which simplifies the setup process for each test. Users interact with the machine through a touch keypad and LCD screen, streamlining parameter setting and data review. Adjustable clamps accommodate samples of various thicknesses, promoting effective testing for a broad array of material types and panel specifications.


Standards Compliance and Data Handling

Fully compliant with ASTM D374 and ISO 4593 standards, the tester guarantees precise, industry-recognized results. Dedicated thickness analysis software and USB/RS232 ports enable direct digital data export, facilitating fast and accurate reporting. The automated data processing system enhances workflow efficiency, especially in busy industrial and research environments.
