Delta Elektronika BV
Is the unidirectional flow or movement of electric charge carriers (which are usually electrons). The intensity of the current can vary with time, but the general direction of movement stays the same at all times. As an adjective, the term DC is used in reference to voltage whose polarity never reverses.

PGK 70 HB -
BAUR Prüf- und Messtechnik GmbH
Cable testing and diagnostics with the BAUR PGK HB. There are hardly any other longer-lasting, more robust and cost-effective testing devices than the two-piece high-voltage test devices from the PGK HB series. They generate continuous adjustable test voltages with mains frequency or optionally DC with positive or negative polarity. The display instruments for current and voltage, the safety control unit and the regulating transformer for the voltage are integrated in the operating unit.* Testing of medium- and high-voltage cables* DC voltage testing of up to 70 kV output voltage with positive or negative polarity* AC voltage testing - up to 55 kV for switchgear, busbars and insulating elements* Easy-to-maintain 2-piece design

Alpha Lab, Inc.
The meter measures the magnitude and polarity of static charge on objects or surfaces. The sensor is calibrated for measuring a surface at 1" from the end of the sensor. On metallic or conductive surfaces, the meter measures the voltage on the surface. (As with any electrostatic voltmeter, the displayed reading depends somewhat on the size of the object being measured and the distance between the object and the sensor.) On insulating surfaces, "voltage" is not a well-defined number. In this case, the meter reads a number proportional to the static charge present.

8473D -
Keysight Technologies
The Keysight 8473D is a high-performance detector using a gallium arsenide, planar-doped barrier detecting element. It features extremely flat frequency response over its entire band of operation and very good frequency response stability versus temperature. The Keysight 8473D is also very rugged with high resistance to ESD damage. An optimum square-law load and positive polarity output are available as special options (consult your local Keysight representative).
