Trek’s 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 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.

Measurement Range: 0 to ±2 kV DC or peak AC

Voltage Display Accuracy: Better than 1% of full scale, ±1 digit 14

Input Characteristics: Resistance greater than 1 x 10 W -14 Capacitance less than 1 x 10 F

Voltage Monitor Output: Scale factor at 1/1000 

• 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.

• Semiconductors
• Materials research
• Photovoltaics
• LEDs
• MR head sensors
• Other ESD sensitive devices
