High Voltage Detector


285 HD

High Voltage Probe Meter


PD-40AM

The 285 HD High Voltage Detector is primary used to detect the presence of an alternation field. It shows identification of AC voltages. 285 HD has a large LCD that is housed in an ABS enclosure. 285 HD can be attached to the cable by a large metal clip and can be secured with a cable tie. The high voltage detector senses the radiated magnetic filed surrounding the cable and shows a LIVE warning sign on the LCD.

FEATURES
● Three different ranges of identification of AC voltage:
285-A HD : 3~7 kV
285-B HD : 6.6~11 kV
285-C HD : 10~22 kV
● The LCD will "flash continuously" for high voltage testing.
● Physical contact with electrical conductors is not necessary when testing for live wires.
● The 285 HD senses the radiated field that surrounds live conductors.
● Radiated field strength increases with voltage and decreases quickly with distance.
● Large LCD.
● Continuous monitoring.
● Easy to install.
● No batteries required.
● Weight : Approx. 80g.
● Meets EN 61326-1
EN 55011
EN 61000-4-2
EN 61000-4-3
