Application
Handheld portable structure for water quality in drinking water and source water ,surface water, groundwater and aquaculture water like ammonia , nitrite , dissolved oxygen , PH, sulfides , phosphates ( or nitrate ) , chlorine 7 Determination of water
quality parameters.

Working principle
In a single wavelength , when certain conditions such as when the optical path , the
absorbance of the solution is proportional to its concentration in certain substances ,
namely Lambert - Beer law.
III Measuring range and resolution
PH: 5.0-9.5pH Resolution : 0.1pH
DO : 0.1-10.0mg / L Resolution : 0.1mg / L
