Technical Specifications
Manual Test Hammer is the traditional instrument used for
the non-destructive testing of hardened concrete.
This easy-to-use instrument provides a quick and simple
test for obtaining an immediate indication of concrete
strength in various parts of a structure.
The minimum verifiable strength is 1400 PSI (10 MPa)
Digital Test Hammer is and advanced completely
automated system for estimating concrete compressive
strength. Its calculation, memory and recording functions
allow for suick, easy and accurate test results.
Discard values for multiple test results can be set; the mean,
median and compressive strength can also be calculated.
The addition of modern microprocessor technology allows the
data to be stored, printed and transferred to a personal computer
for further analysis, or inclusion in your reports.
The unit comes wirh an integraed alpha - numeric digital display,
and control panel. Can switch between standard or metric units.
The field printer mounts on the ease of use/
Connection to a personal computer is via the RS-232 interface.

It is recommended that calibration of the test hammers
be checked regularly - usually after about 2000 strokes.
Cooper Technology’s New Generation Pressure Aging Vessel (CRT-PAV1) uses heated, pressurised air to simulate longterm
oxidative aging of asphalt binders. The PAV consist of an ASME Boiler and Pressure Vessel Code and CE certified
stainless steel pressure vessel, steel cabinet with encased band heaters, and integral pressure measurement control.
This state of the art system meets ASTM D6521, AASHTO R28, and EN 14769 requirements and includes a platinum RTD
device to ensure accurate temperature resolution and uniformity. A pressure relief valve and high- temperature thermal
shut-down are included as standard safety features. A USB port located on the front of the unit allows the user to
easily store test data and upgrade software when necessary.
The CRT-PAV1 Pressure Aging Vessel uses a Touch-screen controller with front panel user interface for complete control
and monitoring of all test processes. The system has an operating pressure range of 2.1 ±0.1mPa and temperature
range of 80°—115°C, with resolution of 0.1°C.
This easy-to-use system completes a test in three simple steps:
1. set the temperature and pressure
2. insert specimens
3. press the start button
The CRT-PAV1 includes a set of ten specimen pans, a precision anodized aluminum sample holder with lifting
handle, and a specimen handling tool. Additional pans can be ordered as necessary. Compressed air with a pressure of
at least 350psi (2.4MPa) and a regulator must be user provided.
