A non-contact instrument that tests AC or DC relay and solenoid operation. Sensitive enough to detect the magnetic field generated by tiny "ice cube" relays. Standard and
high sensitivity models available (see below).
This magnetic sensing probe is a completely safe, non-contact probe
which allows troubleshooting without schematics or special training while eliminating time consuming and cumbersome hookups. It detects residual magnetism, transient current
pulses ("glitches"), in AC and DC-powered solenoids, relays, or any device using a coil. You can safely and easily identify and separate electrical from mechanical problems accurately and inexpensively.
Just place the probe tip close to the coil in the device. If the LED is on, the device is energized; if the LED is off, the device is de-energized.
The Mag-Probe is constructed of non-conductive materials to reduce the risk of shorting live circuits. It also uses a small internal lithium
battery (included) and can be used in situations where lead content is a concern.
Two models to choose from!
Standard Model S: tests large and standard-sized solenoids and relays.
High-Sensitivity Model HS: tests the full range, from the largest to sub-miniature devices.
