NEWTRY Handheld Digital Electrostatic Field Meter Tester 0~30KV Portable Ion Balance Tester 0~300V for Fiber Yarn Fabric Carpet Board Paper Rubber (0-30kv)

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. It is mainly used to measure the electrostatic properties of textile raw materials and finished products (including fibers, yarns, fabrics, carpets, decorative fabrics), paper, rubber, plastics, composite sheets, etc. under laboratory conditions. 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. Specifications: Model: FMX003 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) Ion balance: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 “Power”, then press “IB” Weight(battery not included):0.17kg Size(cm):165mm*25*115mm
