DT Series Drop Weight Impact Tester
|
The DT Series drop weight impact testers are suitable for drop weight tear test to various kinds of ferrites, especially to pipeline steel. The unit is equipped with different weights and anvils and can perform other types of impact tests according to customers’ special request.
Features
-
Impact energy is adjusted by lifting height and the number of weights.
-
The buffer is equipped to absorb the residual energy after breaking the specimen to protect the weight and anvil from destroying.
-
The unit is equipped with safety features, such as safety net, safe pin for maintenance and hanger locking.
-
The tester also has a specimen-carrying system, anti-falling devise for the specimen, centering set-up to guarantee quick, accurate and reliable tests.
