pH Meter HI 5521

pH meter for laboratory with graphical LCD screen / 

pH, ORP (Redox), TDS, conductividad, resistividad, salinidad, temperatura

The laboratory pH meter HI 5521-02 is designed with the latest technology for the highest standards in laboratory and research fields. The pH meter is easy to handle and impresses with its large graphical LCD screen to provide all the information. Contextual help can be accessed through the large screen for operating the meter. The laboratory pH meter HI 5521-02 features automatic 5-point calibration in the pH range. A customer-specified 5-point calibration is also possible. The "Cal Check™" function of the laboratory pH meter compares the latest calibration data with previous ones. For conductivity analysis, the HI 5521-02 allows measurements in 6 different measurement ranges: pH, ORP, EC, resistivity, TDS, and salinity. For EC analysis, it has a wide measurement range from 0.001 µS/cm to 1 S/cm, with automatic recognition of the type of probe used. Salinity measurement can be displayed as practical salinity, seawater, or percentage. Another key feature of the meter is the ability to perform the three stages of analysis required by the United States Pharmacopeia for ultrapure water quality (USP). The HI 5521-02 meter comes equipped with USB and RS-232 ports for PC connection and offers memory and GLP functions.
