RH-450 Carbon Paper Through-plane Resistivity Tester

Introduction:

RH-450 Carbon Paper Through-plane Resistivity Tester is used to measure the through-plane resistivity of PEM fuel cells carbon papers, bipolar plate or other materials.

Standards:

GB/T20042.6 Proton exchange membrane fuel cell—Part 6:Test method of bipolar plate properties
GB/T20042.7 Proton exchange membrane fuel cells—-Part 7 :Test method of carbon paper properties

Test Method:

Carbon paper was sandwiched between two copper plates. The setup is pressed by specific loads from 0.05 up 4.0MPa. During the test, the instrument automatically figures out the electrical resistance of different pressures by recording the current and voltage values at different pressures. (The sample shall not exceed the area of the copper plates.)

Technical Parameters:

Through-plane Resistivity Tester

DC Low Resistance Tester

Product Features:

1. Using high-precision force sensor and thickness sensor, factory accuracy control in <0.5%, better than the ISO standard ±1%.
2. Fully automatic test, The instrument can be connected to a computer, the data can be synchronized to the computer software, and reports and graphs can be automatically generated.
3. Precision ball screw drive, aluminum alloy panel, high-quality red copper gold-plated upper and lower pressure plates and reasonable design ensure that the instrument is durable. Our professional programming team can upgrade the instrument.
4. High resolution touch screen display in English/Chinese, human-computer interface.Automatic test with statistical data handling. Using the micro printer, also can connect the computer operation. When it connected to a computer, it can automatically saves test results, also can display test curves of pressure-resistivity and save.
5. Using high-performance stepper motor, Silicon Labs’chip control, to ensure the instrument transmission precision, fast and efficient testing.
6. The calibration procedure is specially set inside the instrument to facilitate the measurement and calibration department (third party) to calibrate the instrument.Enter the calibration test procedure, put the standard sensor between the upper and lower pressure plates, you can easily carry out the calibration of indicating value error.
