Thermal Resistance and Thermal Conductivity Measurement Instrument for Interface Materials

Based on the steady-state heat-flux method, a controllable heat source is used to introduce heat, which is transferred via a hot measurement rod to the sample under test and then conducted through a cold measurement rod to the water-cooled heat-sink end for dissipation. Temperature data at multiple points are acquired using measurement rods wrapped with thermal-insulation materials, and the sample’s thermal conductivity is calculated accordingly.
Test scope: thermal interface materials such as thermal pads, thermal gels, and thermal greases.

Constant Temperature and Humidity Test Chamber

It simulates complex environmental conditions such as high-temperature high-humidity, low-temperature low-humidity, and temperature–humidity cycling, enabling assessment of product performance stability under various temperature and humidity levels. The temperature control range is -40°C to 150°C.
Test Scope: Evaluation of the Environmental Aging Resistance of Thermally Conductive Insulating Materials

Withstand Voltage Tester

By applying an AC or DC voltage ranging from 0 to 10 kV, the insulation withstand capability of the material is tested over a duration of 1 to 60 seconds to determine whether breakdown, flashover, or excessive leakage current occurs. Voltage accuracy: 5% of full scale.
Test Scope:
AC mode: power-frequency insulation withstand voltage test;
DC mode: Insulation strength testing of DC equipment.

Thermal Conductivity Tester

Based on the steady-state heat-flux method, a constant temperature gradient (ΔT) is applied across the upper and lower surfaces of the sample to measure the vertical heat flux (Q) through the sample. The thermal conductivity (λ) is then calculated using the formula λ = Q·d/(A·ΔT), where d is the sample thickness and A is the cross-sectional area. This method is suitable for analyzing the thermal conductivity of both homogeneous and heterogeneous materials.
Test scope: thermally conductive silicone sheets, thermally conductive gels, thermally conductive silicon greases, etc.

Particle Analyzer

Based on the principle of laser diffraction, it can rapidly and accurately measure the particle size and size distribution of samples such as powders, emulsions, and suspensions.
Test scope: Particle size distribution of various powders.

Hardness tester

Based on the Shore hardness testing principle, a high-precision displacement sensor is used to measure the penetration depth of a needle-shaped indenter into a silicone gasket under a specified load, directly outputting the Shore A hardness value (0–100 HA).
Test scope: elastomers with hardness characterization.

Volume Resistivity Tester

The constant-voltage test method is used for rapid insulation resistance measurement, with continuously adjustable output voltage, capable of testing resistances ranging from 500 Ω to 9.9 × 10¹⁵ Ω.
Test scope: insulation resistance and leakage current of various dielectric materials; the accompanying electrode box can be used to measure surface resistivity and volume resistivity of materials.

Imaging Tester

Utilizing a high-definition industrial camera and a telecentric optical lens, the system captures surface-reflection or backlight contour images of the workpiece and, in conjunction with a CNC-controlled automatic worktable, performs dimensional measurements. It can detect two-dimensional geometric parameters such as length, angle, radius, and distance, while providing real-time analysis and report generation.
Test Scope: Non-Contact Measurement of Precision Parts

Lever dial indicator

A lever–gear transmission mechanism is employed to convert the probe’s minute displacement into pointer rotation, making it suitable for radial and axial runout measurement of complex workpieces.
Test Scope: Planar Detection of Rigid Objects

Roughness meter

An inductive displacement sensor and a diamond stylus are used; the stylus slides along the workpiece surface, converting microscopic surface profile variations into electrical signals, from which roughness parameters such as Ra, Rz, and Rq are calculated.
Test scope: Surface inspection of hard materials.

Hot Disk Thermal Conductivity Meter

Based on the Transient Plane Source (TPS) technique, a dual-helix probe—integrating both heating and temperature-sensing functions—is used to simultaneously measure a material’s thermal conductivity (λ), thermal diffusivity (α), and specific heat capacity (cp) across a thermal conductivity range of 0.005 to 1800 W/m·K.
Test scope: Supports samples in multiple forms, including solids, liquids, powders, thin films, and foams, and is compatible with both isotropic and anisotropic materials (such as laminated composites).

Micrometer

Based on the principle of screw micrometry, the relative displacement between the fixed anvil and the movable micrometer screw is used to measure dimensions such as the outer diameter, thickness, and length of workpieces.
Test scope: various measurement scenarios, including outer diameter, inner diameter, and depth.
