ESD Electric Resistance Tester
SL-030 surface resistance tester in accordance with ASTM standard D-257 test method, simply placed in the need to measure the object surface, press the red button, the instrument of ten 103-1012ohms per square LED will light up one of the test values. Test through the tester at the bottom of the two parallel electrodes to quickly test the object surface conductivity. Simple operation, easy to carry, takes up no space, reliable quality, is the ideal choice for measuring surface resistivity.
