HI 98140 and HI 98150 are two of the most innovative portable pH meters ever offered. These instruments feature IP 67 waterproof protection, GLP (Good Laboratory Practice) capabilities and use HANNA instruments' intelligent electrodes.
These electrodes incorporate a chip which memorizes the calibration data performed with a specific instrument. When the "intelligent electrode is attached to the meter again, it is automatically recognized. This technology allows the operator to optimize time and efficiency with unsurpassed safety. It avoids erroneous measurement readings in the event that the pH electrode is substituted after calibration. This electrode series are equipped with a built-in temperature sensor; no need for an additional temperature probe here!
HI 98140 and HI 98150 feature all the most advanced features of laboratory pH meters. Moreover they are provided with a dual level LCD which enhances operability in dimly lit locations.
By pressing a button, these meters can store up to 500 measurements complete with date and hour. Stored data can be displayed later or downloaded to a computer through an RS232 serial port and the HI 92000 Windows® compatible software.
