Hand-held Static Meter, Positive & Negative Dual Indicator Tester, 100v-20kv Non-Contact Electrostatic Field Testing Tool for Fiber Yarn Fabric Carpet Board Paper Rubber

• PORTABLE ELECTROSTATIC TESTER-- surface electrostatic voltage tester, electrostatic field test, simple operation and sensitive test.
• ZERO ADJUSTMENT-- positive is cleared by one button, and negative is cleared by one button. Just press the corresponding button to complete.
• MEASUREMENT METHOD-- Keep a distance of 1cm from the measured object, move left and right/up and down/vertically, all can be measured, whether the measured object is charged-positively charged red light/negatively charged blue light.
• MULTIPLE USES-- measurement of surface of meltblown cloth, static electricity of non-woven fabrics, static electricity of circuit boards, static electricity of foam plastic bags, static electricity of self-adhesive and other objects.
• NOTE-- This electrostatic tester only detects whether it is electrified, and does not have an exact electrostatic voltage value. It only performs electrified test measurements.
