Hand-Held Electrostatic Voltmeter

Model 821HH

• Measurement Range: 0 to ±2 kV DC or peak AC
• Voltage Display Accuracy : Better than 1% of full scale, ±1 digit
• Input Characteristics: Resistance greater than 1x10 14 Ω /Capacitance less than 1x10 -14 F
• Voltage Monitor Output: Scale factor at 1/1000

Trek's Model 821HH Infinitron © Hand-Held Electrostatic Voltmeter represents the next generation of contacting precision surface voltage measuring instruments, providing input characteristics far beyond the limits of any currently available hand-held voltmeter product.
The Model 821HH can easily measure the voltage level of both conductive and insulative objects and surfaces with virtually zero charge transfer to the measurement probe. This results in stable high accuracy voltage measurement capability for ESD-sensitive devices.

Applications

• Semiconductors
• LEDs
• MR head sensors
• Other ESD sensitive devices

Features and Benefits

• Battery or line operation
• Easy to read LCD display
• Records voltage, temperature and humidity
• Data graphing capabilities
• 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.
