How to use the SL-030B Heavy-Hammer Surface Resistance Tester
The SL-030B digital heavy-hammer surface resistance tester evaluates the antistatic capabilities of products by measuring their resistance. It adheres to the ASTM D-257 testing standard; to perform a test, simply place the two heavy-hammer probes on the surface of the object being tested and press the red button-the instrument will then display the measured surface resistance value.
Features: The "Low Battery" indicator lights up when the battery voltage drops below 5V; features a digital display; and serves as a multifunctional tester capable of measuring ambient temperature, humidity, and object surface resistance.
