Geosynthetic Testing Equipment
TSY-11 Geosynthetic Clogging Tester (Gradient Ratio Determiner)
This equipment is suitable for testing geosynthetic filter layers and has been developed and manufactured in accordance with standards such as JTG 3460‑2026 “Test Procedures for Geosynthetics in Highway Engineering,” SL 235, DL/T 5886, and others. It measures the hydraulic conductivity and permeability ratio of soil–geotextile systems and their interfaces under specified flow conditions, as well as determines the silt content of geotextiles, thereby assessing whether a geosynthetic used as a filter layer for a particular soil will cause unacceptable clogging.
TSY-12 Fully Automatic Vertical Water Permeability Tester for Plastic Drainage Boards
Plastic drainage boards, also known as geosynthetic drainage strips or plastic sheets, are commonly used strip‑type drainage materials with a cross‑sectional width of 10 cm and a thickness of approximately 5 mm.
TSY-13 Geotextile Thickness Gauge
This instrument employs the lever principle to amplify the length of the force‑applying arm, enabling thickness measurements under test pressures of 2 kPa, 20 kPa, and 200 kPa within a compact footprint and using limited‑mass weights. With its simple yet elegant design and user‑friendly operation, it is the preferred choice for manufacturing and calibrating the thickness of geotextiles and geomembranes.
TSY-14 Soil Membrane Permeability Coefficient Tester
Based on the SL 235 and DL/T 5886 standards for the design and fabrication of geosynthetic materials, this test method is suitable for determining the permeability coefficient of various geomembranes under hydraulic pressure. It is applicable to all types of waterproof geomembranes, offering stable performance and convenient, practical operation.
TSY-15 Sodium-Based Bentonite Waterproofing Blanket Permeability Coefficient Tester
Based on the standards JG/T 193, DL/T 5886, and SL 235 for determining the permeability coefficient of sodium‑based bentonite waterproofing blankets, this device has been developed and manufactured. It is suitable for measuring the small seepage that occurs in sodium‑based bentonite waterproofing blankets under a specified pressure differential. By measuring the seepage flow rate through the specimen over a defined period of time at a prescribed hydraulic head difference, and taking into account the specimen’s thickness, the permeability coefficient can be calculated.
TSY-16 Naki Bentonite Hydrostatic Pressure Tester
The sodium‑based bentonite hydrostatic pressure tester is designed and manufactured in accordance with the JG/T 193 standard for determining static water pressure. It is suitable for measuring the hydrostatic resistance of various sodium‑based bentonite waterproofing blankets and features a compact structure and simple operation.
TSY-17 Geomembrane Hydrostatic Pressure Tester
Suitable for measuring the hydrostatic pressure resistance of various geomembranes, with stable performance and ease of use.
TSY-18 Fabric Membrane Bursting Strength Tester
Suitable for measuring the tensile strength of various geomembranes, with stable performance and ease of use.
TSY-19 Geosynthetic Vertical Permeability Tester (Hydraulic Engineering Standard)
Suitable for measuring the vertical permeability of various geotechnical materials, with stable performance and ease of use.
This product is suitable for UV‑induced aging tests on materials.
TSY-25 Fully Automatic Bentonite Filtration Vector Analyzer
This product is tested in accordance with the provisions of JC/T 593 to determine the volume, in milliliters, of filtrate that passes through a suspension under specified test conditions.
TSY-26 Plastic Drainage Core Strip Compression Buckling Strength Testing Machine
This instrument is suitable for determining the compressive yield strength of plastic drainage core strips.
TSY-27 Geotextile CBR Puncture Tester
It is suitable for testing the tensile strength of geotextiles, geomembranes, composite geomembranes, plastic geogrids, drainage‑and‑detection boards, bentonite waterproof blankets, and other geosynthetic materials, and features an LCD display and user‑friendly operation.
LBT-1301 Fully Automatic Laser Particle Size Intelligent Analyzer
Widely used in cement, ceramics, pharmaceuticals, emulsions, coatings, dyes, pigments, fillers, chemical products, catalysts, drilling muds, abrasives, lubricants, coal powder, sludge and sand, dust, cells, bacteria, food, additives, pesticides, graphite, photosensitive materials, fuels, ink, metallic and non-metallic powders, calcium carbonate, kaolin, coal-water slurry, aluminum‑silver paste, manufactured sand, and other powdered materials.
LBT-1172 Handheld Thickness Gauge for Plastic Films and Sheets
This thickness gauge is suitable for determining the thickness of plastic films and sheets using the mechanical measurement method (not applicable to embossed films and sheets).
LBT-1173 Plastic, Film, and Sheet Coefficient of Friction Tester
The friction coefficient tester is based on the GB 10006 standard and is specifically designed to measure the static and kinetic coefficients of friction for materials such as plastic films and sheets, rubber, paper, cardboard, woven bags, textile‑style materials, metal‑reinforced tapes used in communication and optical cables, conveyor belts, wood, coatings, brake pads, wiper blades, footwear materials, tires, and more. By assessing a material’s slip resistance, manufacturers can control and optimize production quality and process parameters to meet product performance requirements. Additionally, it can be used to evaluate the slip characteristics of daily‑use chemical products, including cosmetics and eye drops.
