Product Short Description: Distinct yellow colour test Product Description: Colorimetric Procedure The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout. Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.

Product Short Description: Nitrites are useful as corrosion inhibitors, preservatives, pigments, and in manufacturing many organic preservative chemicals. A Maximum Contaminant Level of 1 mg/L has been established by the USEPA for nitrite-nitrogen in drinking water. Product Description: ::Very simple 3 step procedure :: Applications and Industries: Industrial process waters, boiler water, cooling waters Chemistry: Results are expressed in ppm (mg/L) sodium nitrite (NaNO2).
