PRODUCT DATASHEET WQ500 Series Benchtop Water Quality Meters/Stirrer Magnetic stirrer inside the beaker 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 * Models WQ510 and WQ530 Additional Features * recognizes 4 calibration solutions 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 * Stirrer with 30, 60 and 120 minute timer or continuous * Splash-proof keyboard * Complete with pH glass electrode, pH calibration Adjustable Conductivity to TDS ratio from 0.5 to 1.0 Model WQ530 Additional Features * the built-in USB interface * One point Conductivity calibration - automatically Manual salinity (0-50ppt) and altitude (0-20k ft) compensation for DO measurements See next page for specifications 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 (1413S and 12.88mS); WQ530 also includes DO probe, plastic burette, polishing paper , 4 membrane caps and DO internal fill solution (30mL) Ordering WQ500...............
