Mobile Durometer/ hardness scales HRC, HB, HV and
NDT device suitable for determining the tensile strength Rm / for components up to 1 mm thick.
The durometer can be used to quickly check the hardness of components even when they are installed. The durometer impresses with its large measuring range, easy handling, robust design and temperature resistance down to -20°C. In addition to the hardness in Rockwell, Brinell and Vickers, the durometer can also be used to determine the tensile strength of steels up to 1740 MPa. The uci durometer has a manual test probe with a test force of 50N as standard, with this probe it is possible to measure from all directions in space without a correction factor.
Another advantage of the durometer is its NDT feature. At the tip of the probe there is a Vickers diamond which is excited in the ultrasonic frequency range. If the diamond touches the test piece surface during the hardness test, the vibration is damped. The resulting frequency shift is directly related to the surface hardness of the test piece. Due to the low test forces, the penetration depths of the diamond are very small, which is why only an almost invisible impression remains.
The uci durometer is therefore used for checking small thin-walled components, for surface-hardened test specimens or for nitrided components. The durometer has also proven itself in the measurement of weld seams and the inspection of components with complex geometries.
In addition to the UCI measuring method, the durometer can also be equipped with a rebound tester. This allows the durometer to be upgraded to a Leeb durometer.
The universal durometer combines the advantages of two methods: Ultrasonic Contact Impedance (UCI) and Dynamic Rebound (Leeb). This allows the user to solve almost any field hardness testing task.
The universal durometerr enables express hardness testing of carbon and structural steels, welds, electroplated coatings, overlays, heat resistant, corrosion resistant and stainless steels, hardness measurement of hardened surfaces, thin-walled hardened parts, even in hard-to-reach places and at any angle.
Ultrasonic contact impedance (ASTM A1038)
With the UCI probe, hardness testing of small, thin specimens with complex shapes is now possible. With the UCI probe, the user can measure the hardness of grooves, small radius surfaces, shaft necks with mirror-like surfaces, gears and blades.
Rebound hardness test according to Leeb (ASTM A956)
With a dynamic type D probe (Leeb probe), the user can test the hardness of solid parts with rough surfaces. The instrument can be equipped with additional interchangeable probes with different dimensions and spring stiffnesses.
Main function
This instrument has all the functions for working with materials and scales, making it a universal instrument for non-destructive metal hardness testing.
The one-point calibration allows the creation of a user-defined hardness scale based on an available sample with known hardness. This advantage allows the user to calibrate the durometer as accurately as possible to approach the accuracy of a stationary durometer. It also allows the user to measure the hardness of a large batch of products quickly and with high accuracy.
With the PCE-3000ULS, the user can create and store more than 500 hardness scales and view the history of all measurements after testing. The UCI probe is pre-calibrated for steel. The Leeb probe is pre-calibrated for steel, cast iron, stainless steel, aluminium, bronze and brass, copper.
Standard Rockwell, Vickers, Brinell and Shore calibrations are also available. The user can create and correct additional calibrations for soft and hard materials.
Key benefits of the PCE-3000ULS universal durometer:
- Large colour display with bright backlight.
- Stable operation under difficult climatic conditions.
- Extended temperature range (frost-proof down to -20 °C).
- For long-term operation under field and workshop conditions, the instrument is designed in a dust
proof housing.
- Rubber buffers protect the unit from accidental shocks or falls from a height of up to
5 m, while the unit remains fully functional.
- 2 detachable probes: Ultrasonic contact impedance (UCI) and dynamic rebound (Leeb).
- One-point calibration function (type calibration)
- The unit has the functions of displaying the minimum, maximum and average
hardness values, the function of filtering out of range false readings.
- The function of simultaneous display of 20 measurements in a series enables the analysis of the
with a large number of measurements and significantly increases the speed of processing the
results of the results considerably.
- Function to create diagrams for a series of measurements helps visualise the
hardness measurement over the entire surface of a dimensionally stable product.
- For expert work to achieve maximum accuracy, it is possible to set the
sensitivity coefficient and to adjust the signal processing of the probe.
- The automatic storage of all measurements avoids data loss and allows, if necessary, an analysis of
the data after a longer period of time.
