Brief Introduction to the Device
PCE-HT 224E Digital Rebound Apparatus is a product designed according to
Technical
Regulations for Concrete Compressive Strength Test by Rebound Method
(JGJ/T23-2001)
(hereinafter referred to as
Regulations
) and developed in order to meet actual
requirements for the field test of concrete compressive strength, applicable to the non-
destructive testing of common concrete compressive strength in all kinds of construction
engineering. It is specifically applicable to the on-site quality sampling inspection by
Engineering Quality Supervision Institutions and Supervising Units, for the compressive
strength test result of the inspected concrete structure can be got immediately; when the
Construction Quality Testing Institution carries out on-site test for real construction objects,
it can further reflect the fairness, scientificity and accuracy of the test, greatly improving
the working efficiency of testing, data processing and inspection report formation.
PCE-HT 224E Digital Rebound Apparatus has the following characteristics: integrated design,
small in size; adopt non-contact optical coupler sense to realize data collection, without
changing the original physical structure of mechanical rebound apparatus, in which way the
optical coupler sensor has no contact nor friction with the mechanical part of rebound
apparatus and thus its service life is extended; inside of the apparatus, national curve and
local curve are provided, can be set optionally by yourself; angle, tested surface, pumping
or not, carbonization depth and other parameters can be set on site; after detecting data
of original value, the original rebound value, testing zone strength value, component overall
strength value and other data of the completed component can be checked immediately;
self-contained access control further reflects the fairness and safety of the test; equipped
with USB data transmission interface, able to transfer data to computer; computer software
saves the test data as Excel format, and reporting format can be created immediately,
simple and convenient for the later software process; memory space of original data are as
much as 1000 components.

Structure of Concrete Test Hammer
The Concrete Test Hammer is mainly composed of flip system, value-indicating system and
shell component
.
Its structure is shown in Fig
