The Shore hardness tester generally belongs to what is called a rebound hardness tester, which measures hardness by dropping a diamond hammer weighing approximately 36g from a height of about 19mm and measuring the rebound height of the hammer. The uniformity of the weight of the diamond hammer is high at ±1g, and it achieves high precision with a drop height of 19mm ±0.3. Additionally, by maintaining high precision, it features high compatibility of parts, making it easy to replace the diamond hammer. It also adopts a unique mechanism that allows for easy adjustments of the machine, making maintenance straightforward.

A flat-type device that can precisely measure soft soil, primarily used for measuring the mud of rice fields and the sediment of lakes and ponds.

This device is a portable hardness tester capable of measuring the hardness of various samples with cutting-edge high precision, a wide measurement range, and easy operation. It is ideal for hardness testing under various conditions and environments.

● Compact, lightweight, and easy to operate. It has no structural failures. ● A portable type that is convenient to carry, capable of measuring any size or shape of workpiece (sample). ● The hardness reading is Shore hardness. It can be quickly converted to Rockwell, Brinell, and Vickers values using a hardness conversion table. * Items with a mass of 4 kg or less, hollow (thin-walled) items, and thin plates cannot be measured. ● Differentiation based on application The SPS1 is ideal for measuring the hardness of flat and curved surfaces (convex surfaces). It is convenient for cases where measurement of special shapes, such as the tooth bottom of gears, is not required. The SPS2 has a contact part with the workpiece that is shaped with sharp angles. Therefore, it can measure the hardness of gear tooth bottoms (module 3 or higher) and special recesses. Additionally, by attaching a cap for flat measurements, it can also measure the hardness of flat surfaces and both concave and convex surfaces.

● Not only for test specimens, but also for any products or materials other than hollow thin-walled pipes, testing can be easily conducted regardless of size. ● The testing method is as follows: (1) Place the 5mm diameter steel ball at the tip of this device perpendicular to the surface of the test material, (2) Press the rounded part of this device with your hand, (3) Due to the internal mechanism, a constant force is applied to the steel ball, creating an indentation in the test material. (4) Measure the diameter of the indentation with the attached microscope and determine the Brinell hardness from the hardness table. ● In the case of steel, there is a nearly constant relationship between Brinell hardness and tensile strength, so tensile strength can also be estimated approximately using a separate table. * Manufactured according to the manufacturer's internal standards. * Not compliant with JIS. * The standard "hardness table" is for steel. * There is also an "aluminum hardness table," but it serves as a reference based on the manufacturer's experimental values.

Recently, the trend towards larger machines and structures has become prominent, and consequently, the need for simple and rapid inspection methods for large components has increased. This device is designed to be as portable as possible while maintaining sufficient accuracy without the typical decrease in precision that often accompanies miniaturization. Additionally, it takes into account improved stability during handheld measurements. Combined with ease of operation and lightweight design, it demonstrates its true value in the field.

Schmidt test hammer for normal and high-strength concrete

Hardness tester

The measurement time (load holding) can be set arbitrarily, enabling the measurement of soft workpieces that could not be measured with conventional hardness standards. By adopting a voice coil motor in the load generation mechanism, load settings can be adjusted according to the target workpiece. (※1) Since it is possible to set a low load starting from 0.002N, it allows for the measurement of soft workpieces that could not be measured conventionally. The stress relaxation time of the workpiece can be determined. Additionally, since the measurement time can also be set arbitrarily, it is possible to quantify the softness of gel-like materials that have no rebound force.

The handheld hardness tester is completely different from conventional hardness testing machines; instead of measuring the size of the indentation on the material using a microscope, it applies a diamond indenter with a constant load to the material surface and measures hardness by providing ultrasonic longitudinal vibrations.
