HI 8915
Portable instrument for measuring pH / mV / ° C output for recorder

HI 8915 is a portable instrument for the measurement of pH, with automatic temperature compensation and the ability to connect a recorder to an analog output. In fact, the two output connectors on the front panel can be connected directly to a plotter or a tape recorder to print the measured values.
The large LCD displays pH, ORP, or temperature and the corresponding indicator unit measure. Pressing the ‘HOLD’ reading is fixed on the display, so that you can write it down. The 2-point calibration is performed manually by adjusting the trimmers on the front panel of the instrument.
As an accessory, is available HI 721311 Rugged carrying case for transporting the instrument in the field, complete with 2 sachets of calibration solutions at pH 4 and 7 and calibration screwdriver.
