It is a technologically advanced that allows making careful adjustments pH or ORP in industrial applications.

SIMPLE SET
Thanks to the functional microswitches is simple configure and it is not necessary to go into programming.
EASY TO MEASURE
The calibration has never been easier: the tool able recognize the buffer solutions, automatically making calibration, suspending the dosage and indicating the state of efficiency of the electrode.
UNIVERSAL FOOD
The instrument can be fed with the same tension between 22 and 265 Vac.
DEGREE OF PROTECTION IP 65
Series PR-75 is protected by the box polopropileno, that protects the electronics, wiring and even The BNC to connect the electrode.
electrical isolation OUT OF 4 ... 20 mA The ideal solution to connect with a VCR or with a data acquisition system, without any interference.
