Notify me when its in stockThe PCE-HT 224E concrete test device is developed to measure the compressive strength of concrete non-destructively, widely used in construction engineering.
Designed to meet the requirements for testing concrete compressive strength, this device is also known as the "Schmidt hammer."
The reason for this naming is that the device was developed by Swiss engineer Ernst Schmidt.
The HT-224E concrete test device is ideal for on-site sample quality assessments by instantly determining the compressive strength of the examined concrete structure.
Measurements are performed according to the Schmidt principle.
The calculation method for the test area is as follows: 16 measurements are taken in each test area. Three maximum and three minimum values are discarded, and the average of the remaining 10 values is taken to calculate the rebound value.
The device's integrated mechanism applies a constant impact energy of 2.207 Nm with each measurement, providing consistent and reliable test results.
The precision and reliability of the device in field tests can be directly observed.
Its compact and integrated design makes it easy to carry.
The device features a non-contact optical sensor that can collect data without altering the rebound mechanism's structure. This sensor is long-lasting as it operates without contacting mechanical parts and creating friction.
Parameters such as test angle, surface characteristics, and carbonation depth can be adjusted in the field.
After measurements, data such as original value, rebound value, test area strength value, and component strength value can be instantly displayed and analyzed.
The package contents of the HT-244E device: PCE-HT 224E Concrete Measurement Device, mini USB cable, sanding stone, software (link provided in the description), charger, carrying case, and user manual.
Data can be transferred to a computer via USB interface. With integrated software, data can be saved in Excel format, and user-specific reports can be created.
Basic Functions and Parameters of the Concrete Test Device
Number of Tests and Test Area: According to regulations, 16 measurement points are specified for each test area. The test area is used to measure the compressive strength of concrete in an area no larger than 0.04 m².
Calculation of Concrete Strength: The equivalent strength value of the concrete is calculated taking into account the obtained rebound value, the strength measurement curve, and the carbonation depth.
Test Angle and Surface Adjustments: If the rebound mechanism is not in a horizontal position or the surface is not the concrete pouring surface, the device automatically makes angular corrections.
Carbonation Depth: The carbonation depth, formed by the concrete losing its alkalinity due to chemical corrosion, is entered in the range of 0.0 - 6.00 mm to calculate the strength value.
Strength Measurement Curve: The device includes four different curves:
National Standard Pumping (National standard for pumped concrete)
National Standard Non Pumping (National standard for non-pumped concrete)
Specific Curve 1
Specific Curve 2
(These curves can be uploaded to the device via software according to special test needs.)
Viewing of Strength Value: The tested surface and rebound value can be displayed simultaneously. The average value is not taken; maximum and minimums are not excluded. Therefore, results should be evaluated as reference.
