Description
Benchtop Multiparameter Water Quality Meter – EZDO | PL-700 Series (ALS / PCS / PDS / PVS)
The EZDO PL-700 series benchtop meters are designed for laboratory water quality analysis requiring simultaneous multi-parameter measurement. Each model targets a specific combination of parameters: the PL-700ALS measures pH, conductivity, dissolved oxygen, and temperature; the PL-700PCS covers pH, conductivity, and temperature; the PL-700PDS covers pH, DO, and temperature; and the PL-700PVS covers pH, ORP (mV), and temperature. An optional magnetic stirrer (S suffix) can be integrated into any model for continuous sample agitation during measurement.
All models share identical measurement performance and physical specifications, with the parameter combination and supplied accessories being the key differentiator. The large backlit LCD provides simultaneous display of primary measurement and temperature. ATC ensures accurate pH readings across 0–100°C. Data output via included software and USB cable enables PC logging.
