Fiber Specific Resistance Tester Digital Specific Resistance
Testing Instrument 1.Product Introduction The GA-3A type fiber specific resistance tester is a newly
developed digital specific resistance tester. The instrument
digitally displays the test results in real time through
high-precision AD conversion, and the operation process is
controlled by a computer. The test results can be displayed,
printed and stored. The instrument has a precise structure and accurate, stable test
results. The instrument automatically compresses the chemical
fibers in the measuring box, replacing the manual operation of
turning the hand crank to compress the sample. The operation is
simple. An additional device can be selected for testing the
specific resistance of synthetic fibers. The instrument complies with the requirements of the national
standard GB/T 14342-2015 for test methods and is suitable for the
specific resistance tests of various chemical fibers and natural
fibers. It can be widely used in chemical fiber, textile
enterprises, testing institutions and research units. 2.Product Paramter Resistance measurement resolution | 0.01(10nΩ,n = 1, 2, 3, … , 14) | Resistance measurement range | 10Ω~1014Ω | Resistance measurement error | ≤±5%(resistance ≤1012Ω),≤±10%(resistance >1012Ω) | Test voltage | Two settings: 1V and 100V. High resistance measurement range:105Ω to 1014Ω (measurement voltage: 100V), Low resistance measurement range:
10Ω to 107Ω (measurement voltage: 1V) | Voltage deviation | ≤±3% | Test box | When the sample is in a compressed state, the fibers occupy 4 cm of
the width of the electrode plate, 6 cm of the height of the plate,
and a 2 cm distance between the plates. The insulation resistance
between the two electrodes should be no less than 1014Ωor no less than 10 times the expected value of the fiber's
resistivity. | Test sample | Chemical fibers, chemical fiber yarns (with optional additional
devices) | Calibrated resistance | Three resistors, namely 102Ω, 106Ω and 1010Ω | Power supply | AC 220V ±10% |
