Multiparameter Water Quality Analyzer B-One MW-575B

B-ONE MW-575B Benchtop Multiparameter Water Quality Analyzer

The B-ONE MW-575B Benchtop Multiparameter Water Quality Analyzer combines pH/mV (ORP)/pX, ISE, conductivity/TDS/salinity/resistivity, dissolved oxygen (DO % & mg/L), and temperature in one rugged IP54 unit with a bright 5.7-inch LCD. It offers up to 5-point calibration (pH & ISE), auto-read/timed/continuous modes, GLP-ready data storage (500 results per parameter), and USB/RS-232 connectivity—making it ideal for labs, plants, and field benches that need fast, traceable results.
