JOSBY Electrostatic Voltmeter with Zero Button Function, Portable Static Electricity Tester 0-50kv, for Testing on Non-Woven Fabrics

【Automatic Range Selection】This electrostatic voltmeter supports measurements from 0 to 50 kV and has an automatic flow rate selection function. Provides 3 readings per second with accuracy within ±10%, delivering fast and reliable electrostatic data for quality control and static control on production lines. 【Easy to Use】Equipped with a dedicated reset button, the device allows quick reset before each test. The power switch is located on the side and the clear digital display shows measurements directly in kV. Simply align the edge of the sensor with the target surface, maintaining a distance of 2 in and a perpendicular angle of 90°, to achieve stable readings with ease. 【Portable Design】With its compact size (4528 × 2559 × 30 mm), the unit is easy to grip and store. Comes with a protective case to prevent scratches or damage during transport. Its lightweight design allows convenient electrostatic sample checks on site in workshops, laboratories or warehouses. 【Contactless measurement】 Thanks to the non-contact detection, the device ensures that the tested samples remain intact and free from scratches or damage. It is ideal for measuring static electricity on materials such as meltblown fabrics, non-woven fabrics, plastic sheets, packaging films and other insulating materials, widely used in industries such as packaging, textiles, electronics and anti-static manufacturing. 【Monitoring Tool】Specifically designed for electrostatic measurement, static solving problems, performance verification and routine antistatic monitoring. Its simple and intuitive design is ideal for quality engineers, production operators and staff responsible for handling electrostatic protection.
