Simple operation.

This easy-to-use titrator offers an economical entry level unit that has a powerful titration system to measure moisture content of liquids, pastes and gels.  It shares many of the features of the Aquamax KF but does not include an integral printer.  Its wide range means that it may be used to assess both the quality of incoming feedstock product and finished product.

The instrument is designed to measure the water content of oil samples in a coulometric Karl Fisher titration cell. The amount of electrolysis current required to produce the necessary amount of iodine to counteract the moisture when a known volume of sample is added to the cell is monitored, and the result calculated and converted to ppm, mg/Kg, % or µg water.

This simple to operate unit has up to 10 pre-programmed methods that comply with ASTM standards.

The unit can be connected to "Results Manager" software to review and print sets of results.
