The S-Online for online determination of sulfides provides the opportunity to measure sulfides/H₂S even below the odor threshold in wastewater. By the combination of a highly efficient gas extraction and a selective detection method, sulfide/H₂S is determined in aqueous solutions.

OnlineH2S includes a microcontroller-unit for a quantitative determination of the released H₂S from the sewer with sensor technology at two or more selected measurement points. It serves as the basis for H₂S-adapted regulation of chemicals for water treatment in sewage systems.

The H2S-Analysator creates the opportunity for analysis of hydrogen sulfide in gases and liquids in only one device.

The OnlineNH3 is used for a quantitative determination of NH₃ in livestock buildings, digestion towers and biogas plants. The sampling can be carried out at one, two or more selected measuring points. This measurement serves as the basis for water treatment and the control of maximum threshold values.

The AQUA 40.00 basic module is the essential device for microcoulometric water determination according to Karl-Fischer-Titration in liquid samples and gases.

The PocketTitrator is a truly portable and easy to use coulometric titrator: Titrations with electrochemical reagent generation – simple by one “click” in the user-friendly software.

The Acid Number Titrator is designed for the determination of free fatty acids in oils and fats. Its operating mode complies with IEC 62021-1:2003 and ASTM D664-95 standards for mineral oils.

The GasExtractor is a fully automated vacuum degassing unit for extracting gas from oil and other highly viscous liquids according to international standards. The determination of the total gas content is performed by fast and precise determination of the pressure increasing.

Aquamax KF Plus titrators have been specifically designed for the determination of water content, combining coulometry with the Karl Fischer method. The Aquamax KF Plus titrators are conform to standards for water determination ASTM D 1364, ASTM D 1533, ASTM D 3401, ASTM D 4928, ASTM D 6304, ASTM D 6869, ASTM D 7995, ASTM E 1064, API Ch. 10.9, BS 6829:1.5, DIN 51777, DIN EN 60814, DIN EN ISO 12937, EI / IP 386, EI / IP 438, ISO TC 158/SC, ISO 10101-1, ISO 10101-3, ISO 10337 (see standard conformity).

The Aquamax KF PRO LPG fulfils the requirements of the standard ASTM D 7995 - 19: Standard Test Method for Total Water in Liquid Butane by Liquefied Gas Sampler and Coulometric Karl Fischer Titration.
