The Model 7905 Digital Exair Static Meter allows easy one-hand static measurements. In most cases, the highest voltage reading will indicate the source of the static problem. The digital static meter is sensitive and responsive. The static meter indicates the surface voltage and polarity on objects up to 20 kV when measured one inch (25mm) away.
The Digital Static Meter features a push button "hold" for readings, a low battery indicator and an automatic "power off". A "zero" button to zero the instrument ensures an accuracy of 5% of the reading when it is one inch (25mm) from the charged surface.
