อุปกรณ์วัด pH (portable meter pH / ORP)

HI 9125
portable meter pH / ORP

HI 9125 is a portable pH / ORP microprocessor, Waterproof casing, can provide accurate results even under harsh environmental conditions.
A large LCD display, with clear information about the status of the electrode and the instrument displays simultaneously measures pH and temperature and also provides graphic symbols to guide the operator through the calibration.
The pH calibration procedure is automatic, with 5 memorized values ​​(pH 4.01, 6.86, 7.01, 9.18 and 10.01) , function of buffer recognition and automatic temperature compensation.
Moreover, HI 9125 can be used with electrodes for measuring ORP in the mV range, with automatic change of resolution of 0.1 to 1 mV for readings greater than 700 mV.
The BEPS (Battery Error Prevention System) automatically switches off the instrument when the battery level is too low to ensure reliable readings.
