This is an instruction manual that describes the Hanna HI 3849 Hydrazine Test Kit, which is used to measure hydrazine levels in water.
This document is the instruction manual for the Hanna Instruments HI 3849 Hydrazine Test Kit. It outlines the contents of the kit, including reagents, deionized water, a checker disc, glass vials, and a pipette. The guide explains that hydrazine is used as an oxygen scavenger in high-pressure boiler feedwater and reactor cooling water.

Hydrazine is extensively used as an oxygen scavenger to inhibit corrosion in high pressure boiler feedwater and reactor cooling water.
The sample must be allowed to sit for 12 minutes to allow the color to develop before testing.
Hydrazine reacts with the reagent in acidic solution to form a yellow complex, where absorbance is proportional to concentration.
