GTJ-U200 concrete ultrasonic rebound hammer
Usage overview
The GTJ-U200 Concrete Ultrasonic Hammer is a comprehensive
instrument for testing the strength of concrete. It can be used as
an ordinary rebound tester or as an ultrasonic rebound
comprehensive tester. It can measure the rebound value as well as
the sound and sound speed. It is suitable for non-destructive
testing of common concrete compressive strength in various
construction projects.
Features
※ New upgrade, adopting three-proof shell design, waterproof,
dustproof and shockproof.
※ Multi-function: The compressive strength of concrete can be
tested by two methods: rebound method and ultrasonic rebound
method. It can measure the rebound value, and can measure sound and
sound speed, which is simple and convenient.
※ High quality: Imported sensors and advanced ARM processor, the
test is fast and accurate, and the test results can be analyzed on
site.
※ Easy to use: Full English interface with prompts, quick learning
to conduct on-site testing.
※ Powerful: The instrument can store 4000 sets of data, and record
the test date at the same time, which is convenient for users to
view the management. The USB interface can quickly import data to
the host computer for analysis and processing.
