F230 Wireless concrete crack width gauge is used to measure crack width in concrete buildings such as houses, roads and bridges.

The instrument is designed and made as per T0625 "Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)" in the Industry Standard of People's Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids.

The instrument is a set of products through the combination of a variety of components. It is a new type of test apparatus that can complete both the mechanical property test of rock and the mechanical property of soil. The apparatus adopts the flat push method and is mainly applicable to the direct shear test of rock masses, structural surfaces (such as joint surfaces, layer surfaces, sheet surfaces, incised surfaces and other locations) and concrete (or mortar) and rock contact surfaces (cemented surfaces), as well as the shear strength test of the combined surfaces of concrete and other materials or the whole. The instrument structure is simple, light, intuitive, easy to maintain, can be used in the field, test data digital display, test results are accurate and reliable.

Fully Automatic Triaxial Testing System Apparatus model is adopting the most advanced technology. It is integrated the technology of mechanic, electronic, fully-automated control and sensor automated checking. The range of Triaxial Loading Frame has been designed to be used as part of computer-controlled triaxial system with stress path Triaxial Testing System or as a stand alone unit. Consist of Triaxial Loading Frame and Advanced Pressure Volume Controller (APVC). Both are built up with the LCD graphical display and panel keypad.

The Centrifuge extractor is used for the determination of bitumen percentage in bituminous mixtures. All models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminum box. They are driven by an electric motor fitted with an AC drive (inverter) with the double function of speed control up to 3600 r.p.m. The control panel includes the Start/Stop button, speed control knob, and digital display. The centrifuge extractor is complete with filter paper and bowl.

The Direct Shear Test is an experimental procedure conducted in geotechnical engineering practice and research that aims to determine the shear strength of soil materials. Shear strength is defined as the maximum resistance that a material can withstand when subjected to shearing. Generally, the Direct Shear Test is considered one of the most common and simple tests to derive the strength of a soil and can be performed on undisturbed or remoulded samples.
