อุปกรณ์วัด pH (meter Portable pH / ORP food)

HI 9125F
meter Portable pH / ORP food

HI 9125F is a portable pH / ORP microprocessor, Waterproof casing, fitted with a special electrode FC400B for analysis in food.
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), recognition function buffer and automatic temperature compensation.
addition, HI 9125 can be used with ORP electrodes to measure the mV range, with automatic resolution from 0.1 to 1 mV readings greater than 700 mV.
instrument works with 3 AAA batteries. The BEPS (Battery Error Prevention System) automatically switches off the instrument when the battery level is too low to ensure reliable readings.
