Schnier Electrostatic Coating Equipment Residual Voltage Monitor/ESC 03
Automatically and repeatedly monitors the high-voltage residual of electrostatic coating equipment, complying with standards EN50176 and EN50177.
Model ESC 03/02, for negative polarity.
Model ESC 03/03, for positive polarity.

The residual energy monitor mainly consists of a measurement and evaluation unit, an aluminum die-cast housing, and a calibrated high-voltage precision resistor.
Precision resistors are available in different designs and can be adjusted according to actual usage conditions.
