The ORP57 has a stability indicator, along with a "HOLD" function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. The ORP57 includes a temperature probe for fast and precise temperature measurement.
The modular design allows easy electrode and battery replacement.
