Portable electrostatic tester

TR7300 Type

The electrostatic voltage tester is a simple instrument used to measure electrostatic voltage, it is small, portable, and easy to use. It has a microprocessor inside that turns the electrostatic tester on or off via a power switch (red). A button marked "ZERO" is used to make a zero adjustment, and a button marked "HOLD" is used to keep the data displayed, which is very useful when the display is difficult to read during the measurement.

Features:
• Measure the magnitude of static electricity;
• Establish a sound process electrostatic standard;
• Eliminate materials that are prone to static electricity;
• Observe where and why static electricity is generated;
• Detect if the static eliminator is effective and installed in the best position.

Ion balance measurement of ionizers

In the ion balance (IB measurement mode), the ion balance of ionizer fans, ionizer guns, ionic nozzles, ionic rods, etc., and anti-static equipment can be checked to verify their performance.

Widescreen LCD display

It is easy to view the bar chart and the value of the charge of the charged object to be measured.

Electrostatic measurement

The bar graph shows that the charged potential of 20 kV can be measured at a distance of 25 mm± 20 kV.

LED Focus-Measurement Distance Positioning Function

Approach the charged object until the two focusing rings overlap, as a criterion for the distance to reach the charged object.
