Features
- 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 per cm to 200 to 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
