Universal reagent exchange module


The Aquamax KF PRO LPG is designed for an easy and accurate determination of water in liquefied and gaseous samples such as LPG and LNG.

The new device combines coulometric Karl Fischer method with an unique gas evaporation and dosing procedure.

The Aquamax KF PRO LPG includes all features required for ppm level water in LPG and Gas including, the sulphur removal cartridge eliminating the side reactions caused by sulphides/H2S. Our sample loop principle allows you to fully automate the measurements, up to 125 per day!

All Aquamax KF PRO LPG parts are totally enclosed making this system completely safe and robust for use in the demanding petroleum industry.

The unique ECH sample loop allows you to use the instrument in your laboratory with full automation, as a portable/field use analyzer or can be integrated in to your process as an on-line system.
