เครื่องโฟโตมิเตอร์-ความกระด้างทั้งหมด,เหล็ก (Total Hardness and Iron Photometer)

HI 93741

Total Hardness and Iron Photometer with 555 nm LED

          HI 93741 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. In domestic water, for instance, iron can alter the taste and make it unpleasant to drink. It can also stain laundry, damage kitchen wares and favor the growth of certain bacteria. Low levels of iron are also critical in beverage production.

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.

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.

With the portable HI 93741 you can keep a watchful eye over both iron and hardness levels.

Order Information:
HI 93741 is supplied with 3 cuvets, battery and instructions.
