Product details
What are the routine water quality testing items for swimming pools?
The "Swimming Pool Water Quality Standards CJ/T 244-2016" is a version of the old "Swimming Pool Water Quality Standards"
Based on CJ244-2007, the revised version in 2016 added three new testing items and limit values compared to the old version. The testing items are: turbidity (scattering turbidity unit) (NTU), pH, urea (mg/L), total bacterial count (CFU/mL), total coliform (MPN/100mL or CFU/100mL), water temperature (℃), free residual chlorine (mg/L), chemical residual chlorine (mg/L), cyanuric acid C3H3N3O3
(When disinfecting with chlorinated compounds containing cyanuric acid) (mg/L), ozone (when disinfecting with ozone) (mg/m ³), hydrogen peroxide (mg/L), redox potential (mV). The last five items should be used according to the disinfectant used.
Testing cycle and frequency of swimming pool water quality
There is no mandatory requirement for the testing cycle and frequency of swimming pool water quality standards. However, based on the requirements of local governments for swimming pool water quality and testing frequency in previous years, Guan Ao Instrument provides the following water quality monitoring suggestions.
During the peak swimming season in summer, swimming pools need to monitor water quality every two hours. During non peak hours, the water quality of the swimming pool should be tested once a day. If conditions permit, large swimming pools can directly purchase online water quality monitoring equipment specifically for swimming pools. Small and medium-sized swimming pools should be equipped with portable swimming pool water quality testing instruments.
The advantages of the swimming pool water quality testing equipment produced by Guanao brand manufacturers are:1. Compared to traditional reagent test strips, the water quality detection box of Guan'ao swimming pool provides more accurate detection data and faster detection speed.2. Portable and easy to operate.Handheld Box DesignPick up as you go.The operation interface is fully in ChineseThe interface is simple and easy to understand,
Low cultural requirements for users.3. The supporting chemicals for finished products are specialized and dedicated,
Low cost of reagents and consumablesThe later usage cost is reasonable and can effectively operate for a long time.4. Accurate detection and complete project. The water quality monitoring equipment of Guan'ao swimming pool can detect 12 routine items,
Parameters can be freely customized
