Product Description

Main feachures:

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.
