RATION METER IN-LINE TYPE Solution for unstable measurement/"Tighter Accuracy" + "Higher Stability" > The Model-120 replaces the Model-12 as the standard binary concentration meter. All features and performance remains the same. > The Model-121 is a temperature compensated version of the Model-120. It is used where temperature variations may occur. This new technology is effective outside and other non-temperature controlled areas. ^ The Model-122 is designed for stable concentration monitoring using our new optimization program. Effective on applications requiring high accuracy and stable readings. It also features a temperature compensation technology • Hydrogen peroxide in CMP slurry FUJI ULTRASONIC ENGINEERING C0.,LTD.
