Concentration measurement of hypochlorous acid water
From Japan
On 2014-09-04 18:21:10
There is almost no effect on norovirus, and things that can be used for disinfection of fingers, etc. are rare in addition to hypochlorous acid water, but despite the desire to use a type used diluted in terms of cost, although the concentration decreases, it is difficult to manage There was a problem. Since we are purchasing products "weakly acidic hypochlorous acid water super supernormal water 20 liters (concentration 250 ppm)", the measurement range of this test paper is exactly right, so that we can use it with confidence became. Once in a month, you can use one, so there is no problem in terms of cost. We are nurseries about 50 kindergarten children, but the above items have about 4 months. It took fifty thousand yen a year before, but now it is enough to use twice as much as 20,000 yen.
