Extech RE300 ExStik ORP Waterproof Meter
The Extech ExStik RE300 is the World’s first handheld ORP meter used for obtaining oxidation reduction potential (ORP) measurements inside liquids, semi-solids and solids.
The RE300 features a platinum flat surface electrode with a built in reference, allowing for accurate measurements of potential difference (-999 to 999mV) within a sample. ORP measurements are displayed on an LCD screen as both a numerical reading and an analogue bar graph for clarity. Furthermore, up to 15 samples can be stored sequentially within the RE300’s internal memory for download at a later date.
Additional accessories are also available for the RE300; flexible Electrode extension cables for remote measurements, a weighted base for submersible operation and interchangeable electrodes for Chlorine and pH measurement.
