Hanna Instruments HI96741 Low Range Total Hardness and Iron Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 9V Battery

In domestic water, iron can alter the taste and make it unpleasant to drink. It can also stain laundry, damage kitchenwares and favor the growth of certain bacteria. However, low levels of iron are critical in beverage production. Hardness is a consequence of the type of rock layers which the water passes through and of its permanence in the water bearing stratum. Hardness can cause pipe rusting in water heating and cooling systems, reverse osmosis and demineralization plants. It can also increase the consumption of soaps and detergents in industrial washing machines or laundries. HI96741 can provide critical measurements of low range iron and total hardness (magnesium and calcium). The iron concentration in water needs to be monitored since it can become harmful above certain levels. Hardness, on the other hand, is indicative of the presence of calcium and magnesium in water. By passing through various layers of soil and rocks, rain water dissolves some of the mineral substances. With the portable HI 96741 you can monitor both iron and hardness levels. HI96741 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.00 To 4.70 milligrams per liter (ppm) total hardness and 0 to 1.60 milligrams per liter (ppm) iron LR range. 0.01 milligrams per liter total hardness and iron LR resolution. +/-0.11 milligrams per liter +/-5 percent of reading total hardness and +/-0.01 milligrams per liter +/-8 percent of reading iron LR at 25 degree C accuracy.
