The electrostatic field tester is a non-contact portable electrostatic field tester, which can measure the surface electrostatic value of objects and the ion balance of electrostatic eliminating equipment. Principle: Using a given high voltage electric field, release electricity regularly to the sample to generate static electricity, and then the electrostatic quantity, half-life of electrostatic voltage and residual electrostatic quantity are detected to determine the electrostatic performance of the tested sample. Application: It is mainly used to measure the electrostatic properties of textile raw materials and finished products (including fibers, yarns, fabrics, carpets, decorative fabrics) under laboratory conditions. It can also be used to measure the electrostatic properties of other sheets and plate materials such as paper, rubber, plastics, composite boards, etc. Note: Battery is not included due to air traffic control. Specifications: Model: FMX-003 Output: Red LCD for positive charge, blue LCD for negative charge Power supply: 9V, 6F22 manganese battery ;Test accuracy:±10% Measuring range:0 ~±1.49KV (Low range), ±1.0kV ~±20.00kV (High range) Accuracy:±0.1KV (Low range), ±1kV (High range) ; Measuring distance: 1 inch ±0.2inch (25mm±0.5mm) The tester also has an ion balance measuring board, which can measure the residual voltage of electrostatic eliminating equipment. The ionic balance measuring range is 0 ~±200V. LCD display renewal rate:5 times/s ; Response time:1s Working environment:10~40℃, RH:0~60% Sound alarm: automatic shutdown / turn on / beyond the measurable range Automatic shutdown: No operation for about 5 minutes Mode Switching: Electrostatic field:press “POWER” and a beep sound Ion balance (please install ion balance measurement board): Press the Zero and Power keys at the same time, there are two beeps. Weight(battery not included):0.17kg ; Size(cm):165mm*25*115mm
[INTRODUCTION]The electrostatic field tester is a non-contact portable electrostatic field tester, which can measure the surface electrostatic value of objects and the ion balance(0 ~±200V) of electrostatic eliminating equipment.
[ACCURATE TEST] The static meter shell is made of anti-static material, with grounding buckle, ensure that the measurement results are correct and reliable. Measurable range is 0 ~20KV (working distance is 1 inch), equipped with two LED lights to ensure that the measurement is kept 25mm away from the measured object.
[LCD DIGITAL DISPLAY] Red LCD for positive charge, blue LCD for negative charge, 5 times/s LCD display renewal rate, easier to observe and record values.
[SOUND ALARM] Automatic shutdown / turn on / beyond the measurable range.

This meter sensitively displays electrostatic potential. The maximum of 20KV is a bit limiting, but below that range, it seems accurate. The dual-dot distance marker makes it very easy to position the unit correctly with respect to the surface you're measuring.I don't have good calibrated high-voltage references, so I checked this against a known 0-200V power supply. That's at the very low end of this unit's measurable range, but it did detect the voltage, with correct polarity, and with the expected behavior as I varied the voltage or the distance to target.Recommended.
