PHS-3D-01 Lab pH Meter
    ● Large LCD with blue background can display both pH and temperature value at the same time.
    ● It has intelligent functions for automatic calibration, automatic temperature compensation, data storage / recall, and memory max. and min. value etc.
    ● 1~3 point automatic calibration, and it can automatically display the percentage of slope after finishing calibration
    ● There is manual and automatic tempearture compensation, which can be choose. It needs to equips a temperature electrode if user want automatic tempearture compensation.
    ● ℃ and ℉ can be switched freely.

MP521 Lab pH/Conductivity 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.
