WQ500 Series Benchtop
Water Quality Meters/Stirrer
Three models to choose from. All measure pH, mV, and
Temperature. WQ510 adds Conductivity, TDS, and Salinity
measurement. MQ530 has all the features of WQ510 plus
it measures Dissolved Oxygen (concentration/saturation).
All models have built-in Stirrer with 30, 60, and 120 minute
timer or continuous. Manual store/recall 150 readings
and can transfer data directly to a PC via the built-in USB
interface.
Common Features
• Large backlit dual LCD simultaneously displays
measurement and temperature
• 2 or 3 point pH calibration for better accuracy
(4, 7, and 10pH)
• Automatic Temperature Compensation
• Memory stores up to 150 readings
• Readings can be captured directly to a PC via
the built-in USB interface
• Stirrer with 30, 60 and 120 minute timer or continuous
• Splash-proof keyboard
• Complete with pH glass electrode, pH calibration
solutions (4 and 7pH), Temperature probe, electrode
clamp and rod, software and USB cable, AC adapter
and Stirrer; WQ510/WQ530 also include Conductivity
cell, Conductivity calibration solutions (1413µS and
12.88mS); WQ530 also includes DO probe, plastic
burette, polishing paper , 4 membrane caps and DO
internal fill solution (30mL)
Models WQ510 and WQ530 Additional Features
• One point Conductivity calibration − automatically
recognizes 4 calibration solutions
• Adjustable Conductivity to TDS ratio from 0.5 to 1.0
Model WQ530 Additional Features
• Manual salinity (0-50ppt) and altitude (0-20k ft)
compensation for DO measurements
