YY321A Surface Point To Point Resistance Tester
Test the point to point resistance of the fabric.
GB 12014-2009
Surface point-to-point resistance tester is a high-performance digital ultra-high resistance measuring instrument, using the leading microcurrent measuring devices, its characteristics are:
1. Adopt 3 1/2 digit digital display, bridge measuring circuit, high measuring accuracy, convenient and accurate reading.
2. Portable structure, small size, light weight, easy to use.
3. Can be powered by battery, the instrument can work in the ground suspension state, not only improve the anti-interference ability and remove the power cord care, can also be used in fixed occasions external voltage regulator power supply.
4. Built-in timer, automatic reading lock, convenient test.
5.Resistance measurement range up to 0 ~ 2×1013Ω, is the current point to point resistance measurement ability is strong digital instrument. It is the best instrument for measuring the volume resistivity and surface resistivity of insulating materials. The highest resolution is 100Ω.
