TREK, INC. introduced a handheld 2 kV electrostatic voltmeter which enables high-accuracy voltage measurement – in contacting or non-contacting mode – with virtually zero charge transfer. This level of technical capability is important to the semiconductor manufacturing industry, in materials research, and for applications sensitive to electrostatic discharge (ESD). Model 821HH expands the Infinitron product line which leverages the company's ultra-high impedance voltmeter technology. The technology was developed to meet a market need for effective contacting measurement – without charge transfer – of site-specific voltage on devices and materials sensitive to ESD, during their handling and processing. There is no charge transfer because the technology assures that the probe tip assumes the voltage level of the measured object's surface as the tip approaches, resulting in no current flow at the time of contact and therefore no change in surface potential. Applications include semiconductors, photovoltaics, LEDs, and other electronic devices as well as materials research which can impact a diverse group of industries. This unit can be used to measure both conductive and insulative surfaces. Specifications for Model 821HH include 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 500 us for a 1 kV step, and voltage display accuracy of better than 1 percent of full scale.
