Hanna HI 4521-02 Conductivity Meter

multifunction conductimeter for laboratories with a two-channel color display for pH, Redox, temperature, and conductivity

The multifunction conductivity meter for laboratories HI 4521-02 combines pH, conductivity, resistance, TDS, and salinity parameters. In the pH parameter, the multifunction conductivity meter for laboratories HI 4521-02 stands out for its Cal Check™ control and calibration function, with 5-point calibration and custom buffers. The Cal Check™ function, integrated into the multifunction conductivity meter for laboratories, compares new calibration data with previous data during each pH calibration. If the difference between calibration data is too large, the function alerts for cleaning or replacement of the pH electrode or review of the buffer solutions used. If a pH measurement is outside the calibration range, the device alerts on the screen. Additionally, the Cal Check™ function monitors the electrode status after each calibration. An additional support for the user is the automatic recalibration reminder. The measurement range for conductivity of the multifunction conductivity meter for laboratories HI 4521-02 is from 0.001 µS/cm to 1 S/cm. The multifunction conductivity meter for laboratories automatically identifies connected conductivity probes and adjusts accordingly. The conductivity probe measures resistance, TDS, and salinity parameters, and the meter transforms them into the specific magnitude. The large graphical display of the multifunction conductivity meter for laboratories features dual channel indication. Due to these properties and advanced technology, combined with easy handling, the multifunction conductivity meter for laboratories HI 4521-02 is ideal for use in universities, industrial laboratories, or research.
