ETS-Lindgren HI-4433-LFH Magnetic Field Probe 300 kHz - 30 MHz
The HI-4433 series probes feature Automatic Continuous Zeroing. This Automatic Continuous Zeroing feature removes the need for internal zero adjustment and eliminates temperature drift errors associated with other instrumentation. The Automatic Zero feature allows the meter to be used immediately upon power-up, and eliminates concerns about finding a zero.
