About us

ECH is an independent enterprise founded in 1992. The objects of the company are the development, manufacturing and marketing of analytical devices and measuring methods to analyze gas, water, industrial and municipal waste water and technical products, e.g. oil and gas.

The development of devices and methods has been successfully established for the past 20 years in national and international markets.
Important fields of applications are:

  • Laboratory analysis

  • Factory- and process analysis for technical control

  • On-site mobile analysis and on-line instruments

We are able to comprehend customers’ specific problems and enquiries due to our own development of hardware and software. We response enquiries in the areas of development of new analytical measuring methods and application of measuring devices to control complex and technical industrial facilities, e.g. the controlling of waste water treatment plants or the
monitoring of chemical, petrochemical and bioengineered processes.

AQUA 40.00 with LPG/LNG Module

AQUA 40.00 with LPG/LNG Module

The AQUA 40.00 can be used for microcoulometric determination of water content according to Karl-Fischer-Titration in liquid samples, solids and gases. The Basic Module can be upgraded with additional heating modules with high sensitive gas extraction for solids and oils. The instrument is designed for water determination in LPG and LNG. The optimized measuring device allows very low background drift and short measuring times. Therefore the analyzer can be used as a down to trace ppm-analysis.



The H2S-Analyzer determines hydrogen sulfide in solids, gases and liquids. The determination of total volatile sulfides in aqueous solutions and oils works through high efficient gas extraction combined with a selective electrochemical detection method. Thereby, interferences from the sample-matrix will be minimized. Sample preparation is not required. The device can be used in the laboratory or for online-measurements to control waste water treatment and for petrochemicals.

MobilGC 2

MobilGC 2

The portable gas chromatograph MobilGC 2 is suitable for on-site operation, on-line process monitoring and laboratory work. Its special feature is the internal gas supply, which allows the on-site use. It can be chosen between different detectors (FID, TCD, PID) according to the analytical problem. The columns are individually heated. So it is possible to adjust various temperature programs. The comfortable software allows fast and accurate analysis and various evaluation modes.

Determination of water content of gases according to the Karl-Fischer-Titration 

The Karl Fischer Titrator AQUA 40.00 coupled with a LPG/LNG Module is designed for an easy and accurate determination of water in liquefied and pressurized gaseous samples such as LPG and LNG. These device version of AQUA 40.00 are suitable for all types of gases - flammable, inert as well as c...| » Further reading 

SnLayer - Thickness of tin layers 

The thickness of the non-alloyed and alloyed tin layer on thin copper wires can be measured with high accuracy in a short duration by this electrochemical analyzer SnLayer. The coulometric determination of the thickness of the tin layer at the copper wires based on the newly developed multiple ...| » Further reading 

Water determination in oils according to the Karl-Fischer-Titration 

Gas extraction is the ideal method to handle oils, solid and pasty substances. The heating module for oils is an extension module of AQUA 40.00. Oil samples are injected through the septum into the heating oven. It is possible to apply sample volumes ranging up to 20 ml. The high sensitivity of ...| » Further reading
