Aquamax KF PRO LPG
Accurate Water Analysis for LPG and LNG
Downloads
Product description
The Aquamax KF PRO LPG fully meets the requirements of ASTM D7995-19 – the Standard Test Method for Total Water in Liquid Butane by Liquefied Gas Sampler and Coulometric Karl Fischer Titration.
Specifically developed for the easy and precise determination of water in liquefied and gaseous samples like LPG and LNG, the Aquamax KF PRO LPG combines the coulometric Karl Fischer method with a unique gas evaporation and dosing system.
Designed for Maximum Performance and Automation
The system includes all essential features for ppm-level water analysis in LPG and gases, including a sulphur removal cartridge to eliminate side reactions from sulphides and H₂S.
Thanks to the innovative sample loop principle, fully automated operation is possible – with up to 125 measurements per day!
All components of the Aquamax KF PRO LPG are completely enclosed, ensuring maximum safety and durability even in the tough conditions of the petroleum industry.
The unique ECH sample loop design offers full flexibility:
- Use it as a fully automated laboratory instrument
- Operate it as a portable field analyzer
- Or integrate it directly into your process as a powerful online monitoring system
