เครื่องโฟโตมิเตอร์-สังกะสี (Zinc Photometer 0.00- 3.00 mg/L)

HI 93731

Zinc Photometer with 585 nm LED

          Even though zinc is nontoxic to human beings, concentrations above 5 mg/L can cause a bitter, astringent taste.

This level of zinc can result in a milky, iridescent color in alkaline waters and irritate the human digestive system.

Zinc in low quantities, however, is a beneficial and essential element necessary for body growth. In fact, the US drinking water contains an average of 1.33 mg/L of zinc.

Zinc is normally introduced into drinking water through industrial effluents, especially due to dezincification of brass and deterioration of galvanized iron.

In addition to drinking water, zinc is measured in surface finishing, boilers and cooling towers, water conditioning, effluent waters and many other applications.

The HANNA® solution to the measurement of this important parameter is a handy, portable meter that measures zinc from 0 to 3 mg/L in steps of 1/100th of mg/L.

The meter is microprocessor-based to guarantee maximum accuracy and all readings are shown in clear digits on a large LCD.

Order Information:
HI 93731 is supplied with 2 cuvets, battery and instructions.
