JOSBY Portable Electrostatic Voltmeter with Zero Button Function and Carrying Case, Digital Static Voltage Detector for Meltblown Fabrics, Non-Fabrics

【Wide Measuring Range】Electrostatic voltmeter supports measurements from 0 to 50 kV, clearly displaying both positive and negative electrostatic voltage readings (in kV) on the display. Using a non-contact measurement method, the device provides stable electrostatic voltage data when the sensor edge is held perpendicular to the target surface at a distance of 2 in. 【Intuitive Operation】Equipped with a reset button, the device allows a quick reset before each test to avoid deviations. The power switch is conveniently placed on the side for easy use. The meter works reliably at temperatures between -4 °F to 122 °F and at humidity levels below 80%, ensuring stable performance in a variety of work, warehouses and manufacturing environments. 【Complete Accessories】 The kit includes electrostatic tester, 9V battery, zipper case and user manual. The robust protective case protects your device from scratches, bumps and dust during transportation or on-site inspections. Designed for portability, the compact and portable unit can be easily operated with one hand, allowing you to carry out electrostatic tests conveniently anytime, anywhere. 【Test Tool】Specifically designed for electrostatic measurement, quality control, static solving problems, performance testing and routine antistatic monitoring. Thanks to its simple operation and low learning curve, it is ideal for quality engineers, production operators, managers and laboratory personnel. 【Versatile Applications】Contactless design ensures no scratches, marks or damage are left on delicate test samples. It is ideal for measuring static electricity on materials such as meltblown fabrics, non-woven fabrics, plastic sheets, packaging films and other raw materials. It is widely used for quality control in industries such as textile, packaging, electronics and the production of anti-static products.
