Dart Drop Impact Tester
Model No. :
Brand : Thwing Albert
This ergonomically designed instrument measures the impact failure energy of plastic films and coated papers using the free-falling dart method. It utilizes a sophisticated pneumatic clamping system with a dual-stage pressure sequence to ensure specimen stability and operator safety during testing.
-
Pneumatic clamping ensures secure sample placement
-
Dual switches required for safe operation
-
Automatic release for consistent dart drops
− Features
- Ergonomic tabletop design
- Pneumatic dart release
- Wide range of incremental weights
- Weight set included
- Cushioned dart landing area
How it Works
A pneumatic sample clamp is used to secure the specimen in place for ease of operation and operator safety. The operator needs to simultaneously activate dual switches mounted on either side of the instrument to engage the clamp and initiate the dart drop. In addition, the dart drop tester provides a dual clamping sequence. The first phase utilizes low-pressure to safely clamp the sample followed by a high-pressure clamp prior to testing. The final phase of the test is completed with an automatic dart release.
