ABSTRACT:
A combination corrosion probe and sampling device. The probe is flexible such that it can be inserted into a piece of operating equipment such as a distillation column and reach tray surfaces or the like which heretofore have been difficult, if not impossible, to reach with a probe. The probe allows the measurement of the rate of corrosion over a period of time and further includes a thermocouple and temperature compensation means to assure the accuracy of the amount of corrosion measured. The flexibility of the probe is enabled by a portion of the probe being fabricated from a pliant substantially cylindrical member such as a ribbed cable protector. A capillary tube runs substantially the length of the probe having an open end in close proximity to the location where corrosion is being measured. That capillary tube runs to a sampling valve near the opposite end of the probe. This enables the sampling of the process fluid at the location where measurements are being taken so that laboratory tests will show precisely what operating conditions exist at that point.
