Introduction
In order to fulfill the industry's need for
an analog soil resistivity meter that is affordable, available, and
meets M.C. Miller's high standards, we are proud to introduce the M.C.
Miller 400A Analog Soil Resistivity Meter.
The Miller 400A operates exactly like the
Nilsson 400 4-Pin Soil Resistance Meter with
regard to resistance range selection, null balancing, etc. Consequently,
a technician who is familiar with operating a Nilsson 400 will not have
to learn any new procedures to operate the Miller 400A.
The Miller 400A has an IP67 rating for
dust and water intrusion, and it runs on a set of easily replaceable
C-size alkaline batteries. Also, the Miller 400A is built using
state-of-the-art components that are readily available, which means that
we can respond to our customers' needs in a timely fashion.
Note that the Miller 400A does not fit
inside the existing MC Miller soil resistivity test
kit case. MC Miller is in process of developing a new case that will
accommodate the kit items including the new Miller 400A.
The
Miller 400A Users
Manual is posted on this website, providing technical details on the
operation of the unit and its various applications.
Applications
Whether you need to measure soil
resistivity or the resistance-to-earth of an electrode, such as a ground
rod or an anode, the Miller-400A has you covered:
- Determine the average earth
resistivity to a specific depth (4-electrode application).
- Determine the resistivity of a soil
sample, or of a liquid, via an electrolyte (soil/ liquid) box
(4-electrode application.
- Measure the resistance-to-earth of a
buried electrode, such as a ground rod, or an anode, for example
(3-electrode application).
- Measure the resistance between two
buried electrodes, such as two ground rods, or two anodes
(2-electrode application).
