Abstract

A compact corrosion measurement apparatus and system includes an air fan, a corrosion sensor, a temperature sensor, a humidity sensor, a heater element, and an air flow sensor all under control to monitor and maintain constant air parameters in an environment and minimize environmental fluctuations around the corrosion sensor to overcome the variation commonly encountered in corrosion rate measurement. The corrosion measurement apparatus includes a structure providing an enclosure within which are located the sensors. Constant air flow and temperature is maintained within the enclosure where the corrosion sensor is located by integrating a variable speed air fan and a heater with the corresponding feedback loop control. Temperature and air flow control loops ensure that corrosivity is measured under similar conditions in different facilities offering a general reference point that allow a one to one comparison between facilities with similar or different pollution levels.

First claim

What is claimed is:

1. A corrosion measurement apparatus comprising:
a structure forming an enclosure having a first end and a second end;
a corrosion sensor device located within said enclosure;
a first sensor device located within said enclosure for determining a respective air flow value within said enclosure;
a second sensor device located within said enclosure for determining an air temperature value within said enclosure;
a third sensor device located within the encl…
