ABSTRACT:
Instrumentation for measuring the amount of material dissolved in a liquid solution which utilizes electro-optic technology based on the Beer-Lambert Law is implemented either as a portable, battery powered model or integrated in an automated process monitoring system. In the portable, battery powered model, a sample probe (14) is inserted into a solution to be measured. The results of the measurement are displayed on a display (22). The displayed results are frozen for a predetermined period of time at the expiration of which, the power is turned off to conserve battery power. In the automated process monitoring model, a solution loading analyzer (100) is supplied with a sample of solution to be analyzed. A probe (14) positioned in a measurement well (200) is used to determine the ratio of incident light to light transmitted through the sample. A spray nozzle (212) is used for cleaning the probe head (16).
