Horiba LAQUAtwin pH Meters, PH-11, PH-22 and PH-33 Meters
These pocketmeters from the LAQUAtwin series by Horiba measure pH in a single drop of water or water based sample.The meter gives accurate measurements and is lab quality. The applications are multiple as long as the samples carry (some) water. Oil based substances are not suitable. Whether it is plantsap, food, soil samples or the like, with the smallest sample you can get accurate pH readings.
Three Models
You can choose from three models. Depending on resolution and calibrarion points u kan choose the meter of your likes and use it for your purpose. Please check the specifications and make a choice.
Each meter is supplied with pH 4.01 & 7.00 buffers (14ml each), 2 x CR2032 batteries, dropper, instruction and quick manuals.
