ORP Oxidation Reduction Potential Meter Digital Pen Type

Product description:

This ORP meter has been pre-calibrated accurately in advance for your immediate use. It is recommended to calibrate at 265MV buffer solution but can also be calibrated by other buffer solution with different ORP value. NO CALIBRATION SOLUTION IS INCLUDED!

This RISEPRO® ORP meter can measure the amount of Oxidation Reduction Potential (ORP or REDOX) level in sample quickly and conveniently. ORP is a tendency of the solution to either gain or lose electrons. The backlight LCD equipped enables users to do testing and measurement even in dark fields.

ORP is correlated with the quality and purity of water. ORP meter has a wide range of applications in water sources, aquarium, hydroponics, spas, swimming pools and other water systems.
