HI 8424
pH meter sealed

The same features that can be found in the most sophisticated tools to microprocessor laboratory, are also found in the portable pH meter HI 8424.
Thanks to its internal microprocessor, HI 8424 is able to perform a fast and accurate measurements of pH, oxidation-reduction potential (ORP A) and temperature. When the mV reading reaches the value of 699.9 ±, the resolution automatically switches from 0.1 to 1 mV.
The pH measurements are automatically compensated for temperature by connecting the probe supplied, or may be manually compensated for special needs. During the automatic calibration, the instrument recognizes the three default values ​​stored calibration (pH 4.01, 7.01, 10.01) and displays them, eliminating any possibility of error. When you turn displays the percentage of remaining battery power.
Thanks also to the HOLD function you can set the reading on the display to write it down later, you can also set the unit of measurement of the temperature in ° C or ° F, enable or disable sleep mode, the beep of the keyboard and the display backlight. Additional news is an indication of the buffer solutions used in the last calibration.
