Working principleDuring the compression process of external force, as the powder moves and deforms, the gaps are filled, the contact area between particles increases, the atoms are attracted and the mechanical wedging between particles is strengthened, thus forming a compact with density and strength. During the process of forming the compact, the changes in resistance, resistivity and conductivity are measured in real time until they are stable.Product ParametersTest item/modelFT-8600AFT-8600BResistance/square resistance range10^-5~2×10^5Ω/10^-4~1×10^7Ω/Resistivity range10^-6~2×10^6Ω-cm10^-5~2×10^8Ω-cmConductivity range5×10^-6~10^6ms/cm5×10^-8~10^5ms/cmTest current range0.1μA ,1μA,10μA,100μA,1mA,10mA,100 mA10mA ---200pACurrent accuracy±0.1%±2%Main pressure Optional2 tons, 3 tons, 5 tons;Sample height measurement0.001mm-25.000mm; automaticDisplacement stroke0-50mmControl systemServo power control systemDisplay mode7-inch touch screen + PC softwareCompacting mold (national standard)Inner diameter: 13mm; height: 25mm; precision 0.01mmResistivity measurement moldInner diameter 16mm; height 10mm (it is recommended that the sample height after compression is ≤4mm)Pole resistor electrodeStandard configuration: electrode diameter 16mm; other specifications can be customized.Demolding methodAutomaticProtection deviceAutomatic diagnosis, overload protection and emergency stop controlTemperature and humidity rangeNormal temperature -50 degrees; humidity: 20%-98%/Time setting0-99.9SDensity value99.99999g/cm3 Different samples have different characteristics and densities; Error: 1%DeformationCan measure the deformation of elastic materialsResistance test methodStandard four-probe method; four-terminal method (you can choose the corresponding measuring electrodes)Resistance repeatability error≤0.05% (standard resistor) Repeatability error ≤2% (affected by sample differences, uniformity and other characteristics)Displacement speed<15mm/min;0.1mm/minEnvironmental requirementsInstrument use environment requirements: Working temperature: -10oC-40oC, humidity: ≤65%RHPower supply380vBalance (optional)0.00001g, range: 120g; 0.01%Detailed Photos
