EMCO Concentration Analyzer type 570

EMCO Concentration Analyzer Type 570


The EMCO Concentration Analyzer Type 570 is designed to precisely monitor the process with strong acids or bases in % or GPL in the process industry.
The EMCO analyzer measures the conductivity and temperature of the solution.
Complex polynomials correct for changing temperatures. The analyzer then correlate to the concentration of the solution.


The Analyzer is extremely easy to use due to the simple menu structure.
Select the appropriate process recipe followed by the selected chemical fluid and required measuring range and temperature.
The EMCO concentration Analyzer is very suitable for harsh environment in the process industry due to the stainless steel enclosure and IP65 protection class in combination with hinged cover.
The Analyzer can be mounted in a panel (panel opening 138 x 138 mm), on a wall or on a 2” pipe.
The Analyzer can be supplied with hinged look through cover.


The EMCO Concentration Analyzer and the 4 electrode sensor type 711 with internal electrodes for smaller pipe sizes or 721 for larger pipe sizes or vessels are extremely resistant to scale build-up, and offer long time stability, due to their design.
The analyzer offers high sample rate and an internal damping lowers the spikes.

Trend curves on output signal with selectable time period up to 8 hours for easy process check are available. The display is light blue, but turns red in case of analyzer/sensor failure. Galvanic isolated protective & measurement ground for elimination of ground loop noise.

Memory back up for all parameters.
Loop powered version is available, but without display back light.
All vital functions are pass word protectable Low power consumption, max. 4 VA.
User friendly menus are programmable in clear text.
Easy understandable icons reporting successful run of the process and possible alarm points. An external temperature sensor can be connected.


Various recipes for around 20 different chemicals are available
The analyzer contains the possibility to change between 2 recipes for example. between H2SO4 and conductivity.
