The Desco 19442 Digital Static Field Meter indicates surface voltage and polarity on objects. The meter has a measurement range of 0 to +-19.99 kV at a distance of 1 inch and a measurement accuracy of +/-5%. It utilizes a chopper-stablized sensor for use in both normal and ionized environments. The meter’s enclosure is dissipative and features a 7 mm snap and ground cord for bonding to equipment ground. A rotary zero knob sets the zero-reference point with finely tuned precision, and a Hold button allows the user to “freeze” a displayed measurement for evaluation. A LED range indicator assists with placing the meter at the correct distance from the object being measured.
