MultiSensor water analysis handheld instrument

HIGHLIGHTS:

• simultaneous measurement of pH / oxygen or pH / conductivity and the corresponding temperatures
• integrated galvanic isolation enables simultaneous measurement with affordable standards sensors
• the display enables convenient reading of several values simultaneously and the measurement curve in diagram form
• the data logger can be read directly via USB – with standard smartphone cable or software
• simple and convenient battery charging via USB connection

GENERAL:

The G 7500 is a comfortable multi-channel water analysis device for simultaneous measurement of two measurement variables and the corresponding temperature. All significant electrochemical measurements can be combined:
- pH/ Redox + conductivity/salinity
- pH/ Redox + dissolved oxygen

APPLICATION:

• monitoring of bodies of water
• drinking water preparation
• sewage treatment plants
• fish husbandry and aquaculture
• vertical/ urban farming
• conventional agriculture
