อุปกรณ์วัด pH (portable meter pH / ORP Calibration Check ™)

HI 9126
portable meter pH / ORP Calibration Check ™

HI 9126 is a new generation of pH meters: lab quality, accuracy and simplicity in a sleek and portable.
HI 9126 is equipped with diagnostic features that represent a real improvement in the reliability of measures. The exclusive Calibration Check ™ HANNA allows you to keep under constant review the state of the electrode, so as to always guarantee the optimal functioning. For each calibration, the instrument monitors the condition of the electrode, warning the user when it is necessary to carry out further cleaning.
The large display simultaneously displays multi-level readings of pH and temperature, electrode status and operation guide . Simple and clear messages guide the user at all stages of the calibration process.
calibration is performed automatically at 1 or 2 points, with a choice between 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) and 2 values ​​customizable. The user can also set the period of validity of the calibration, by notice to the deadline.
system BEPS (Battery Error Prevention System) automatically switches off the instrument when the battery level is too low to ensure reliable readings.
HI 9126 can also perform measurements ORP in the mV range, with a resolution of 0.1 mV. The temperature range is very wide, from -20 to +120 ° C.
