Testermeter- DZDR-S Transient thermal conductivity meter

Product introduction:
Thermal conductivity tester based on transient plane heat source method (TPS). This
product is independently developed by Dazhan Instrument, with stable test
performance and strong data processing and analysis ability, and can be used for
measuring the thermal conductivity of various types of materials.
Survey object:
Type of material:metal, ceramic, alloy, ore, polymer, composite material, paper, fabric,
foam (flat surface insulation, panels), polyurethane, phenolic, urea-formaldehyde,
mineral wool (glass wool, rock wool, mineral wool), cement walls, glass-reinforced
composite panels CRC, cement polystyrene panels, sandwich concrete, composite
panels with FRP panels, paper honeycomb panels, etc.
Technical specifications:
1. Test scope: 0.0001—300W/(m*K)
2. Measuring temperature range: room temperature - 130 ℃ (can be extended to
300 ℃)
3.Probe diameter: 7.5mm for No. 1 probe; Probe 2 15mm
4.Accuracy: 0.001
5.Measuring time: 5 to 160 seconds
6.Power supply: AC 220V
7.Overall power: <500w
8.Temperature rise of sample: < 20 ℃
9.Test sample power P: probe 1 power 0<P<1w; Power of No. 2 probe 0<P<20w
10.Sample specification: No. 1 probe sample (≥ 7.5 * 7.5 * 3.75mm) No. 2 probe
sample (≥ 15 * 15 * 7.5mm)
11.Equipped with powder sample test container, liquid sample test cup and solid
sample test fixture
12.The software can export PDF reports and EXECL data
Note: The No. 1 probe measures thin, low conductivity materials. Samples can be
stacked if they have a smooth and flat surface and are sticky
Instrument features:
1.The test range is wide, the test performance is stable, and it is at the leading level
among similar domestic instruments;
2.Direct measurement, the test time can be set within 5-160s, which can quickly and
accurately measure the thermal conductivity, saving a lot of time;
3.Does not suffer from the same contact thermal resistance as the static method;
4.No special sample preparation is required, no special sample shape is required, only
a relatively smooth sample surface for lumpy solids and a length and width of at least
twice the diameter of the probe is sufficient;
5.Non-destructive testing of samples, meaning that samples can be reused;
6.The design of the probe using a double helix structure, combined with an exclusive
mathematical model, using core algorithms to analyse and calculate the data collected
on the probe;
7.Cleverly designed and easy to operate sample tables, suitable for holding samples of
different thicknesses and at the same time simple and aesthetically pleasing;
8.The data acquisition on the probe uses an imported data acquisition chip which, with
its high resolution, enables more accurate and reliable test results;
9.The control system of the mainframe uses an ARM microprocessor, which is faster
than conventional microprocessors, improving the analysis and processing capacity of
the system and making the calculation results more accurate;
10.The instrument can be used for the determination of thermal physical parameters
of lumpy solids, paste solids, granular solids, colloids, liquids, powders, coatings, films,
insulation materials, etc.
11.Intelligent man-machine interface with colour LCD display and touch screen control
for easy and simple operation.
12.Powerful data processing capabilities. Highly automated computerised data
communication and report processing system.
