Product Short Description: Reagent of Hydrazine Test Kit 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.
