Abstract
A system monitors the stability of fats and oils especially having the capacity of simultaneous analysis of a multitude of samples making it convenient for use to monitor a production plant. A plurality of probes (made from a metal taken from a group consisting of nickel, chromium, rhodium, titanium and stainless steel) have spaced parallel electrodes immersed in a liquid carrier (deionized water) through which an effluent of heated fats or oils is bubbled. A common conductivity meter responds to signals from each of the probes, in turn, for measuring the induction time of the fats or oils samples. The instrument features a power failure recovery system that utilizes a battery-power clock, so that short duration power failures do not cause a loss of data. A long duration power failure does not cause loss of data to the point of failure, however incomplete analyses are stopped.
