The EFP-3 Electric Field Probe allows fast, easy, accurate measurements of the electric fields in water produced by electrofishers. A front panel function switch selects the units of measurement, either volts per inch or volts per centimeter. The readings drop with time at a rate of approximately 1 millivolt per second. Pressing the reset switch clears the old reading and prepares the unit to make a new reading. The probe is polarity-sensitive. It will only measure positive fields. If a negative field needs to be measured simply turn the probe 180 degrees.
