KEYENCE SK Statik elektrik yük ölçümü

KEYENCE SK Elektrostatik metre

KEYENCE SK Elektrostatik yük nesnelerin yüzeyinde bulunan elektrostatik yük değerinin ölçülmesine yarar. Elektrostatik yükün oluşmasını ve yalıtkan nesnelerde kalıcı olmasını sağlayan nem değerinin de eş zamanlı ölçümü gerçekleşir. Elektrostatik yük değeri ne kadar yüksek ise nesnelere ve bulunduğu ortama karşı bozucu etkiler yaratmaktadır. Elektrostatik hasar, yabancı madde yapışması, nesnelerin birbirine yapışmaması ve birbirinden ayrılmaması sonucu nesnelerin deforme olması ve statik yük nedeni ile kişilerde oluşabilecek stres ve çarpılmalar oluşur. Elektrostatik yükün nötr hale en kısa sürede getirilmesini sağlamak için statik elektrik temizleyiciler kullanılmalıdır.
