Horiba LAQUAtwin ORP-11 Pocket Meter
The HORIBA LAQUAtwin ORP-11 measures oxidation-reduction potential (redox) from -1000 to +1000 mV using the same flat-sensor design as the rest of the LAQUAtwin range — a few drops of sample is all it needs. ORP is the fastest practical indicator of how oxidizing or reducing a water is, which makes it the standard check on disinfection strength and on the redox state of groundwater.
The meter is fully waterproof (IP67), calibrates at one button press, displays temperature alongside the mV reading, and uses a user-replaceable sensor. It ships with 255 mV standard solution, batteries, dropper and storage case.
