These stainless steel check plugs are used as a standard to calibrate equipment
and, therefore, accuracy is imperative. Calibration Plugs are available in 1” and
1 ½" diameter sizes. The external stainless steel shell protects the porous
media and allows pressurization to 2,000 psig. Five plugs are presently considered
a set, and they should cover a range or properties as approximated below. Each set
number with A, B, C, D, and E designating the various properties. They are used
with the Ultra-Perm series of steady-state air permeameters to check the calibration
of the system and to verify the data produced.
These calibration plugs are not primary standards and have been tested by Core Laboratories
Instruments using customary testing methods. However, given the inherent uncertainty
in any laboratory test method, Core Laboratories Instruments does not represent
the accuracy of such results. In any case, the maximum liability Core Laboratories
Instruments will have arising in connection with the purchase and/or use of these
calibration plugs is limited to the price received by Core Laboratories Instruments
from such buyer.
