DZDR-S Thermal Conductivity Instrument Introduction: DZDR-S is a thermal conductivity meter launched by Nanjing Dazhan Instrument, which adopts the transient heat source method. It has a fast measurement speed and can produce results within 5-160 seconds. At the same time, it has a wide measurement range and can measure different materials, including liquids, block solids, metals, powders, coatings, pastes, colloids, etc. The measurement method is simple, fast, and accurate. The DZDR-S thermal conductivity meter can measure different materials such as block solids, paste solids, granular solids, colloids, liquids, powders, coatings, films, insulation materials, etc. The DZDR-S thermal conductivity meter has a wide range of applications, including testing of metals and alloys, diamonds, ceramics, graphite and carbon fiber, filled plastics, polymer materials, etc. characteristic: 1. Direct measurement, with a testing time of about 5-160 seconds that can be set, can quickly and accurately measure the thermal conductivity, saving a lot of time; 2. Will not be affected by contact thermal resistance like the static method; 3. No special sample preparation is required, and there are no specific requirements for sample shape. Solid blocks only need a relatively smooth sample surface and a length and width that is at least twice the diameter of the probe; 4. Conducting non-destructive testing on the sample means that it can be reused; 5. The probe adopts a double helix structure for design, combined with a dedicated mathematical model, and uses core algorithms to analyze and calculate the data collected on the probe; 6. The structure design of the sample table is clever, easy to operate, suitable for placing samples of different thicknesses, and simple and beautiful; 7. The data acquisition on the probe uses a data acquisition chip, which has high resolution and can make the test results more accurate and reliable. Technical parameters: Test range: 0.0001-300W/(m * K) Measurement temperature range: Room temperature -130 ℃ (expandable to -40~300 ℃) Probe diameter: Probe No.1 7.5mm; Probe No.2 15mm; Probe No.3 50mm Accuracy: ± 3% Repetitive error: ≤ 3% Measurement time: 5-160 seconds Power supply: AC 220V Whole machine power: ＜ 500w
