TP-521 Laboratory PH/Conductivity Measuring Instrument

● The most versatile pH + conductivity dual-parameter measuring instrument
● It has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, RS232 output, clock display, function setting and self-diagnostic information.
●There are three different measurement modes: stable display mode; timing measurement mode; continuous measurement mode.
● Automatically identify pH standard buffer solutions. There are three series of standard buffer solutions to choose from: European and American series, NIST series and Chinese series.
●Using conductivity measurement technology, using a conductivity electrode with a constant K=1, only one point of calibration can meet the measurement accuracy requirements of 0.5μS/cm ~ 200 mS/cm.
● Switchable conductivity, TDS, salinity and resistivity. TDS and salinity are calculated using polynomials to ensure the conversion accuracy of the full range.
● The instrument carries the product serial number.
● It meets the IP54 dust-proof and splash-proof rating, and the instrument socket is sealed and protected by a silicone cap.
