MAX Waterproof 4-in-1 (EC, TDS, NaCl, Temperature) Multiparameter Portable Meters

The Milwaukee MW306 MAX Waterproof 4-in-1 EC/TDS/NaCl/Temp Portable Logging Meter delivers accurate, reliable conductivity measurement across an exceptionally wide auto-ranging scale in a rugged, IP67-rated portable design. Accurate to ±1% of reading for EC, TDS, and NaCl, the MW306 is trusted by hydroponic growers, horticulturalists, aquaculture professionals, food processors, water treatment facilities, and lab users who need comprehensive conductivity data in the field. Its easy-to-use logging functions capture up to 1,000 records via log-on-demand or log-on-stability, with USB download for convenient data transfer. It includes the Milwaukee MA815D/1 lab-grade combination EC/temp probe and features a built-in Battery Error Prevention System (BEPS) and internal clock for calibration tracking.
