HTH-225E Digital Concrete Compressive Strength Test Hammer
1.Introduction
HT-225E Digital Concrete Hammer
is a high-tech product, especially designed for the needs of in
place test for concrete compressive strength, applied to
non-destructive test (NDT) hardened concrete compressive strength
component in construct projects.
Digital Test Hammers for the quick and easy determination of the
strength of concrete, and hardness of construction materials.
Digital functions allow faster and greater number of test, leading
to better quality tests. It’s a good and useful instrument for
quality control and inspection organizations. Its power source is
5# Ni-MH rechargeable battery available worldwide.

3.Technical Feature
1) Submit to < Technical
Specification of Inspecting Concrete Compressive Strength by
Rebound Method > (JGJ/T23-2001). And ASTM C805, EN 12504
2) Integrated structure of the test hammer host and the displayer
part. Easy to carry and make work efficient. Digital part is
suitable for all mechanical hammers of our company easily installed
and serviced.
3) OLCD displayer,English interface and friendly operation.
4) Unique automatic recording function improves the efficiency of
measurement.
5) Adopting non-contact reflection grating sensor, maximum avoid
machine attrition and poor contact in traditional technologies such
as contact way or potentiometer way, high precision, long service
life, and the traditional pointer scale is kept.
6) Its power source is 1*5# Ni-MH rechargeable battery available
worldwide.
7) Large storage capacity, more than 200 standard components, a
standard component including almost 50 test areas, one test areas
including 16 test pointes, completely meet the request of long time
in site test.
8) Testing parameters can be typed in test site.
9) Adopting USB interface, as U flash disk, no need special driver.
10) Have real-time clock calendar function, can automatically
record test date.
11) Advanced low power consumption function, can set display
backlight level, auto dormancy, and automatic turn off.
