Extech Benchtop Water Quality Meter/Stirrer 6 Parameter (WQ510)




  • Measures pH, ORP, TDS, Conductivity, Salinity, and Temperature
  • Built-in magnetic stirrer with 30, 60, and 120 minute timer or continuous stirring setting
  • 2 or 3 point pH calibration provides excellent accuracy (4, 7, and 10pH)
  • One point conductivity calibration − automatically recognizes 4 calibration solutions
  • Large backlit dual LCD simultaneously displays parameter measurement and temperature
  • Automatic temperature compensation
  • Memory stores up to 150 readings
  • Readings can be captured directly to a PC via the built-in USB interface
  • Splash-proof keyboard
  • Meter comes complete with pH glass electrode, pH calibration solutions (4 and 7pH), Conductivity cell, conductivity calibration solutions (1413µS and 12.88mS), temperature probe, electrode clamp and rod, appropriate software, USB cable, AC adaptor and a stirrer

This highly accurate 6 parameter meter is designed for use in a lab or benchtop applications. It features a built-in magnetic stirrer and a clamp for holding a probe securely in place in your sample. This meter is ideal for keeping a sample completely mixed or for mixing a sample while simultaneously testing one of the 5 water quality parameters and the temperature.


The large, backlit LCD screen and buttons are splash-proof and highly visible. The easy-to-use controls make testing a quick, simple, and accurate undertaking that practically anyone can do. Included with the meter are everything needed to start testing right away as well as software and a USB cable which allows the user to capture their readings on a PC in real time.
