Portable pH meter ELE-521

laboratorywith conductivity meterTDS meter

• - The most widely used pH + Conductivity Double-Parameter measurement meter. • - Meter meets with the requirement of international GLP standards. Its features up to automatic calibration, automatic temperature compensation, data storage, timing measurement, clock display, RS-232 output, function setting and self-diagnose etc. • - There are three different measurement modes: stable display mode; time measurement mode; continuous measurement mode. • - Automatically recognize pH buffer solution. User can choose anyone from three series of standard buffer solutions: Europe & USA series, NIST series and China series. • - Adopt advanced and original conductivity measurement technology, use 1 pc of conductivity electrode (K=1), it can meet measuring accuracy requirement for range within 0.5μS/cm ~ 200mS/cm by using only one-point calibration. • - Can switch Conductivity, TDS, Salinity and Resistivity. • - Meter has the only product serial number. • - Dustproof and waterproof meter meets IP54 standards. All sockets are seal protected by the silica gel caps.
