RS PRO MP-1 Non Contact Voltage Indicator, 600V to 1000V

RS PRO MP-1 Magnet Stick. Alternating currents, direct currents, magnetic fields and strong magnets are all detectable with the MP-1 from our high quality RS PRO range. The tip of the MP-1 will light up in the presence of magnetic fields, with the reverse side featuring a light for those confined working areas or dark environments. Designed with an ergonomic grip, the light weight Magnet Stick can also be clipped on to pockets or in to tool kits. Features and Benefits:. 2 x AAA battery powered (included) 32 mA work max current -10°C to 50°C (14°F to 122°F) operating temperature 3000 m altitude 48g weight Contaminated Distinction: II. Frequently asked questions:. How do magnetic field sensors and detectors work? Magnetic field sensors are able to detect changes such as direction, strength or flux in a magnetic field. Magnetic field detectors are able to detect fields, such as unipolar, bipolar and electro-magnetic. There are many types of technology used for this and they all have different approaches. Some record the resistance, some have coils surrounding magnetic material, another measures fields against an internal magnet based response that runs through a fluxing set of parameters. Some devices contain switches, when the state of the switch is changed for example from open to closed, a magnetic field has been detected. The most commonly known technologies are Fluxgate, Hall Effect, Magnetoresistive, magnetoinductive and SQUID. (Superconducting quantum interference devices)
