G 7500-PH/CON/O2, Portable Multisensor Meter for Water Analysis, Kit with 3 Probes
G 7500 is a comfortable multichannel measuring device for water analysis. It measures two parameters and the associated temperature simultaneously.
Kit G 7500-PH/CON/O2 contains three probes for pH/temperature, redox and dissolved oxygen.
All major electrochemical measurements are combinable with these:
* pH/redox + conductivity/salinity
* pH/redox + dissolved oxygen
The illuminated graphic display indicates all parameters in plain text in German or English.
Large display or measurement diagrams are also displayable.
The modern device platform uses the common USB cables for charging the internal (interchangeable) batteries and for reading out the data logger without the need of any additional software or adaptor.
The logger is read out comfortably like a USB 2.0 pen drive.
Applications:
- water monitoring
- neutralization processes
- agricultural measurement
- drinking water treatment
- sewage treatment plants
- fish farming and aquaculture
- vertical/urban farming
