SIBATA Handy Chlorine Meter AQUAB AQ-201/ with regent,The AQUAB series handy water quality meters are easy-to-operate water quality photometers. As the concentration conversion curves are pre-programmed, measurements can be performed immediately after zero-point adjustment using sample water. Two-point calibration is enabled by setting to user calibration mode. Up to 99 measurement values can be stored in memory.

■ Main Functions

● Memory function

　 Measurement values are automatically saved up to 99 points.

　 In memory check mode, you can check the measurement value immediately.

● Turning the power OFF automatically or manually

　 The power can be automatically turned OFF even if you forget to turn it OFF. You can also turn the power OFF manually.

● For measuring residual chlorine

Tap water is disinfected with chlorine in order to secure sanitation. Residual chlorine indicates the available chlorine remaining in tap water in a state that it has a disinfecting effect. DPD method is used as a legally-specified procedure to check and measure residual chlorine concentration.

The AQ-201 is a residual chlorine comparator that uses the DPD method. It can measure up to 2.00 mg/L of residual chlorine concentrations and can be used to measure residual chlorine in water in living environments such as buildings, condominiums, schools, factories, swimming pools, and amusement facilities. The concentration of free residual chlorine can be obtained by using only the DPD reagent and the total residual chlorine and the combined residual chlorine concentration can be obtained by using potassium iodide together with the reagent.,
