Paintest Powdatest

The Powdatest is a precision instrument that will measure both electrostatic spray gun high voltages and discharge currents.

With the Powdatest any electrostatic sprayer can now quickly measure the voltage at the spray gun tip. This corona point is where the electrostatic voltage must be maintained at the correct voltage. The spray gun high voltage can be up to 100kV and can be either positive or negative charged. Using the Powdatest the actual gun voltage can be quickly and accurately measured.
There can be many reasons why the spray gun voltage may not be correct. Poor calibration, dirt and grease contamination, poor cable connections, cable breakages etc, all of which could affect the actual gun voltage but not be shown on the spray equipment displays. The Powdatest offers a safe, simple and quick test to establish the correct voltage and is particularly useful for multi-gun systems.
The Powdatest is a combined voltage and current measuring instrument with voltage range to 100kV, resolution to 0.1kV and accuracy ±1%. Will also measure discharge currents accurately to a resolution of 0.1 Micro-amp with a total measuring range of 0-200 Micro-amps. Calibration Certificates having traceability to UKAS are available.
The ability to accurately measure the discharge current during spraying is very important. The Powdatest will allow the operator to determine the optimum gun position and to detect the amount of powder applied before back-ionisation occurs. This is useful to allow spray gun systems with a set discharge current control to be quickly and easily tested.
Supplied with high Voltage Measuring Probe, Current Test Cable, Earth Cable, Carrying Case and Battery fitted.
