The model 289 is ideal for those who need to make qualitative static surveys at the most affordable price.
It features a high-speed LED bar graph that quickly shows the magnitude and polarity of the static charge. A simple-to-operate zero button and conductive case (for obtaining a ground connection) help to make this one of the easiest instruments you will ever operate.
