Greisinger G7500 - Multi Sensor Water Analysis Handheld Device

HIGHLIGHTS:

• simultaneous measurement of pH / oxygen or pH / conductivity and the associated temperatures
• Built-in galvanic isolation enables simultaneous measurements - with inexpensive standard sensors
• the display enables a comfortable reading of several values ​​at the same time as well as the course of the measured values ​​in the form of a diagram
• the data logger can be read out directly via USB – with a standard smartphone cable or software
• simple and convenient battery charging via USB connection

GENERAL:

The G 7500 is a convenient multi-channel water analysis device for the simultaneous measurement of two parameters and the associated temperature. All essential electrochemical measurements can be combined:
- pH/ redox + conductivity/ salinity
- pH/ redox + dissolved oxygen

APPLICATIONS:

• water monitoring
• drinking water treatment
• sewage treatment plants
• fish farming and aquaculture
• Vertical / urban farming
• traditional farming
