Ambient Resistivity System - a state of the art resistivity measuring system features
a programmable RCL meter, pneumatic atmospheric core holder and 2/4 electrode measuring
system. The ARS-200 is specifically designed to assist universities and other teaching
institutions with the hands on instruction process. The ARS-200 provides a modern
state of the art measuring instrument that allows the student to go through the
measurement process in a structured transparent method. The ARS-200 features a pneumatic
atmospheric core holder that allows a consistent loading to be applied to the sample
eliminating operator error from the measurements. The instrument is forgiving in
its operation and does not require mercury nor elevated pressures to operate, enhancing
This instruction-focused design allows the student to build on his basic knowledge
of core Resitivity measurements and their relationship to the correct calculation
of water saturation from the down hole logs using the classic Archie relationship:
Resistivity determinations are usually made in conjunction with porous plate capillary
pressure measurements (CPPP-200 de-saturation cell system) to enable the calculation
of Formation Factor and Resistivity Index values along with the cementation, "m",
and saturation, "n" exponents.
Digital Resistivity Meter is a precision RCL meter; the unit has the capability
to make 2 & 4 electrode measurements. Measurement ranges are: Resistance 0.000 ohms
to 200 Mega ohms, Frequency is 1kHz. In addition capacitance, phase angle, and inductance
