Portable Measurement of Surface Static Voltage

The TREK520 is designed to measure electrostatic voltage on surfaces without making direct electrical contact. This makes it useful when checking charged materials, work surfaces, equipment, and other objects where a contact probe is not practical.

The instrument measures DC electrostatic surface voltage from 0 to +2kV, providing a convenient solution for routine static control inspections.

Non-Contact Testing for ESD Environments

The measurement method allows operators to inspect static voltage from a defined distance while keeping the instrument electrically isolated from the tested surface. This is particularly useful in ESD-controlled work areas and locations where charged surfaces need to be checked without disturbing the test object.

The supplied probe design is intended to provide stable readings during normal measurement procedures.

Fast Response for Changing Static Conditions

With a response time of less than 25 ms and a sampling rate of approximately 2.5 measurements per second, the TREK520 can respond quickly to changes in surface voltage.

This allows operators to observe static conditions during material handling, production processes, and other operations where electrostatic levels may change over time.

Clear LCD Readout and HOLD Function

The instrument uses a 3-digit LCD display to present the measured voltage. A HOLD function is provided so that a reading can be retained for easier observation after measurement.

The straightforward control layout helps operators carry out routine checks without a complicated setup process.

Stable Readings for Routine Inspection

The TREK520 is designed for stable measurement performance under specified operating conditions. Its temperature coefficient is listed at less than 600 ppm/°C, while the time stability is specified at less than 600 ppm/hour.

The specified measurement accuracy is within ±5% of full scale.

Compact Handheld Construction

Measuring approximately 31 mm × 59 mm × 173 mm and weighing around 200 g, the TREK520 is suitable for portable inspection work.

Its compact form makes it convenient to carry between production stations, laboratories, ESD work areas, and other testing locations.
