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 / ORP + conductivity / salinity 
- pH / ORP Dissolved oxygen +

APPLICATION:

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