L800 analyzer can be configured regarding the analysis and the installation to suit your industrial application, for example pure water and process water.
Provided with an ATEX enclosure (zone I or zone II), or including 4-20mA and relay output signals, the analyzer can be easily integrated into your existing installation. With robust elements and a measurement method without chemical consumption, L800 analyzer requires little service and maintenance resources. The instrument may be equipped with multiplexing system to measure several sampling points in a same instruments.

G800 analyser covers an important part of industrial application including petrochemical plants, power plants, gas and paper industries.
Provided with an ATEX enclosure (zone I or zone II), or including 4-20mA and relay output signals, the analyser can be easily integrated into your existing installation. With robust elements and a technology which needs no moveable part, Aether process analyser requires little service and maintenance resources. The instrument may be equipped with multiplexing system to measure several sampling points in a same instruments. For some applications, an industrial oven may be built-in the analyser to maintain the temperature of gas above the due point.
G800 process analyser provides fast measurements of a wide range of pollutants such as ammonia, hydrogen sulphide, nitric oxide, sulphur dioxide, nitrogen dioxide, mercaptans, BTX An innovative mathematical algorithm allows selective and reliable concentration measurements.
