Trek Model 520

The Trek Model 520 (±2kV) Hand-Held Electrostatic Voltmeters provide accurate, noncontacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments. These are an ideal solution for when quick voltage measurements are required, allowing for a more cost effective solution then an oscilloscope. Model 520 is available in two versions. The 520-1 has a digital meter to display the measured voltage. The 520-2 has an analog output monitor in addition to the digital display.
