Model 821HH handheld 2kV electrostatic voltmeter enables voltage measurement – in contacting or non-contacting mode – with reportedly zero charge transfer. Is part of Infinitron product line for measurement  of site-specific voltage on devices and materials sensitive to ESD during handling and processing. Probe tip assumes voltage level of the measured object's surface as the tip approaches. Applications include semiconductors, photovoltaics, LEDs, and other electronic devices, as well as materials research. Can be used to measure both conductive and insulative surfaces. Includes measurement range of 0 to +/-2 kV DC or peak AC, input resistance greater than 1x10E+14 ohms, input capacitance less than 1x10E-14 farads, speed of response less than 500us for a 1kV step, and voltage display accuracy of better than 1% of full scale.
