The Model 281 Static Locator is a high quality, portable non-contacting static meter which produces consistently accurate readings with ease and offers years of trouble-free operation. It will indicate surface voltage and polarity on objects up to ±20kV at a spacing of one inch with an accuracy of 10% of reading. The 281 also features a pushbutton to hold readings and automatic power down to conserve its battery.
