RE: Coulometric Karl Fischer Moisture Analyzer

Dear Kim:

LOOP Inc. purchased a Karl Fischer moisture analyzer from KAM Controls in 1986. This unit was used to compare over 5,000 water by distillation tests to water by Karl Fischer over a four year period on 65 different types of crude oil. Since this time, LOOP has purchased an additional four units from KAM Controls and has changed its crude oil water measurement for custody transfer to the Karl Fischer Method. LOOP is very satisfied with the performance and accuracy of the five Karl Fischer moisture analyzers.

Sincerely,

Roy J. Barrios
