Product.Nr.: G 7500Product Description
general information:
G 7500 is a comfortable multichannel measuring device for water analysis. It measures two parameters and the associated temperature simultaneously. All major electrochemical measurements are combinable:
- pH / ORP + conductivity / salinity
- pH / ORP + dissolved oxygen
The illuminated graphic display indicates all parameters in plain text in German or English, other languages are integrable (charges upon request). Large display or measurement diagrams are also displayable. Our proven standard plug connectors guarantee the use of our standard sensors - intentionally without additional costs due to complex technology in the sensors. Thus the device convinces with its efficiency and the affordable system price (also note our sets). The modern device platform uses the common USB cables for charging the internal batteries (changeable) and for reading out the data logger without additional software or adapter. The logger is read out comfortably like a USB 2.0 data stick.
- simultaneous measurement of pH / oxygen or pH / conductivity
and the associated temperatures - integrated galvanic isolation allows simultaneous measuring – with cost-efficient standard sensor technology
- the display allows comfortable reading of various values simultaneously and of the measurement progression in diagram form
- the data logger can be read out directly via USB – with standard
smartphone cable or software - simple and comfortable battery charging via USB connection
Therefore applications like water monitoring, neutralization processes or agricultural measurements are compactly under your control:
- water monitoring
- drinking water treatment
- sewage treatment plants
- fish farming and aquaculture
- vertical / urban farming
- conventional agriculture
