NEWTRY Electrostatic Field Meter Static Meter 0-22KV Electrostatic Meter Tester 0-200V Static Field Meter for Fiber Yarn Fabric Carpet Board Paper Rubber (0-30kv)

[2 IN 1]: This electrostatic meter can measure the surface electrostatic value of objects (0-±30kv), and can also measure the ionic balance of the electrostatic elimination equipment (0~±300v).
[ACCURATE MEASUREMENT]: Grounding buckle of this electrostatic field tester ensures the correct and accurate results, Measurement range: 0-30kv; Ion Balance Measurement Range 0 ~ ±300V; Measurement Accuracy: ±10%; Equipped with two LED lights to ensure that the measurement is kept 1inch away from the measured object.
[LCD DIGITAL DISPLAY]: Red LCD display shows positive charge, blue LCD display shows negative charge. The 5 times/sec LCD update rate and 1 sec response time make observing and recording data more efficient. Power level also appears on the display.
[SOUND ALARM]: Automatic alarm when the electrometer is turned on, automatically shut down and exceeds the measurable range, which allows you to clearly know the status of the electrometer.
[WIDE APPLICATION]: This electrostatic instrument can be used in laboratory conditions to measure the electrostatic properties of textile raw materials and finished products (such as fibers, carpets, etc.), it also can be used to measure the electrostatic properties of other plate materials(such as paper, rubber, plastic, etc.)
