Resistivity MiniRes Ultra40

Ultra Minires40

Item # 108043

An updated version of the Ultra Minires now offers 40 milliAmps of transmitted current for those longer a-spacings that are becoming more popular. Along with this increase in current is a slight increase in voltage as well - 800 volts peak to peak regardless of load. With a newly designed internal lithium rechargeable battery pack, this Minres40 is easy to use.

The Ultra MiniRes40 is likely the most accurate resistivity and IP field instrument available today. This 2.5 Hz model is a great all-around instrument for grounding and mining reconaissance surveys. At 2.5 Hz, it takes a little longer for the readings (because of the lower frequency rate) but is capable of larger "a" spacings - out to 1000 feet! The accuracy and repeatability have made the Minires a favorite for those working soil resistivity surveys for grounding of power and pipeline protection systems.
