When Water Detection is Critical
Understanding the levels of moisture present in your lubricating oils, gasoline additives, and similar products is essential when evaluating petroleum products for quality and performance. Depending on the product, moisture can lead to premature corrosive wear and an increase in debris.

Coulometric Karl Fischer - HI934
The HI934 Coulometric Karl Fischer titrator is ideal for the detection of trace amounts of moisture. The HI934 analyzes for water content ranging from 1 ppm to 5%.

Volumetric Karl Fischer - HI933
The HI933 Volumetric Karl Fischer titrator is ideal for the detection of water levels greater than 100 ppm. The HI933 analyzes for water content ranging from 100 ppm to 100%.
