The Powdatest Electrostatic High Voltage Meter is a precision instrument that measures 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 a positive or negative charge. Using the Powdatest, the actual gun voltage can be quickly and accurately measured.
