The JRWS measures concrete specific heat capacity, thermal conductivity, thermal diffusivity, linear expansion, and volumetric change. It is used by educational, research, and testing institutions and in concrete construction under GB/T 50081-2019, JG/T 329-2011, DL/T 5150-2001, and SL 352-2006.
The TSX-300 measures the permeability coefficient of pervious concrete pavement bricks by simulating water flow from light rainfall to torrential rain. The instrument references GB/T 25993-2023 and identifies construction-material testing as the application.
The JRWS-06A-50L tester measures the adiabatic temperature-rise curve of concrete with computer-controlled temperature tracking and PID regulation. It references GB/T 50080-2016 and related hydraulic-concrete and hydraulic-asphalt-concrete testing procedures.
The DRX-06D measures the thermal diffusivity of concrete with computer-controlled operation and report generation. It is intended for concrete and asphalt-concrete testing under the listed hydraulic-engineering test procedures.
The Fully Automatic Concrete Thermal Conductivity Tester measures the thermal conductivity of concrete with computer-controlled heating, cooling, and stirring. It is intended for educational, research, and testing institutions and for concrete work in buildings, roads, bridges, dams, reservoirs, and cofferdams.
SYD is a hydraulic strength-testing machine for flexural testing of concrete specimens and compression testing of concrete, cement, mortar, brick, and other nonmetallic building materials. It uses electronic force measurement and offers selectable maximum-load options of 30 kN, 50 kN, 100 kN, 200 kN, and 300 kN; GB/T 3722 is referenced.
The SYD hydraulic cement flexural tester measures flexural strength of concrete specimens and compressive strength of cement, mortar, red brick, and other non-metallic building materials. It uses electronic force measurement and provides selectable maximum-load options of 30 kN, 50 kN, 100 kN, 200 kN, and 300 kN; GB/T 3722 is referenced.
The CL-D determines chloride content in cement and cement raw materials using the distillation method. It is the designated equipment for the chemical-analysis method specified by JC/T 420-2007.
The HSF-Ⅱ determines cement heat of hydration by the direct method and supports heat-of-solution testing for cement and concrete. The direct method tracks cement-mortar temperature change in an adiabatic calorimeter for seven days and reports heat of hydration in J/g under GB 2022-80 and GB/T 12959-91.
The SYD hydraulic compression machine applies load for compression testing of concrete, cement, mortar, brick, and related non-metallic materials. A flexural attachment permits flexural testing of concrete specimens; selectable maximum-load options are 30 kN, 50 kN, 100 kN, 200 kN, and 300 kN, with GB/T 3722 referenced.

The XPD-06D tester measures the linear coefficient of thermal expansion of concrete and can also test asphalt using a differential resistance strain gauge and a constant-temperature water tank. It accepts laboratory-molded specimens and field-drilled cores for engineering quality inspection, teaching, and research.
The instrument measures dynamic elastic modulus, resonance frequency, damping, and internal friction using impact excitation and resonance analysis. It is configured for concrete, carbon, plastics, glass, brick, stone, metals, and other construction and engineering materials.
