C640 Thickness Tester is a high precision mechanical contact method thickness tester, which can be used for thickness measurement of films, sheeting, paper, corrugated paperboard, textiles, non-woven fabrics, and solid insulation materials, etc. Auto sampler is optional, which is designed for multiple successive points thickness measurement.
Features
Professional
With innovative research and development, Labthink C640 Thickness Tester uses high precision displacement sensor, supported by scientific structure and professional control technology, which makes C640 greatly improved in stability, repeatabilityNote1 and accuracy.
-
The instrument conforms to standards for mechanical contact method. The pressure foot can be lifted and lowered automatically, which can minimize the errors caused by human operation.
-
Contacting time and test speed can be set as required. Customization is available for multiple contact areas and pressures, which can meet the requirements for various test conditions.
-
Manual and automatic test modes can be selected by the users
-
Calibration of multiple points can improve the linearity of the whole test range, which ensures the accuracy of measured results.
-
Standard gauge block is available for fast calibration
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 Labthink’s 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.
Note: The described test standards should be in line with Table 1: Test Parameters.
