DEHA (NN- Diethylhydroxylamine) is added to boiler system water as an oxygen scavenger to keep the dissolved oxygen levels as low as possible. Reference: G. Frederick Smith Chemical Co. The Iron Reagents 3rd ed. p. 47 (1980). The test kits employ the PDTS chemistry in which DEHA reduces iron III (ferric state) to iron II (ferrous state ...
For example turbidity or the lack of clarity in a water sample usually indicates that bacteria may be present. The pH value is also considered a general water quality indicator. High or low pHs can indicate how corrosive water is. Corrosive water may

A level indicator whether it be a gage glass indirect sensing method or independent remote is used on a steam boiler to provide a water level reading. A gage glass is the most common form of level indicator found on steam boilers.
Test for contaminants before installing water-treatment equipment such as boilers and filters. You can also check your pipes and equipment for improper chemical levels that can cause corrosion and scale buildup shortening their life.. 367-test kits include tests for six common water-quality parameters in boiler systems and cooling towers.
How to Read a Boiler Water Pressure Gauge | DoItYourself.com
The gauge will have a dial with a needle on it. The needle will be sitting on a number that represents psi (pounds per square inch). Your reading should be a few psi under the MAWP. For instance if your boiler has an MAWP of 30 the gauge should read somewhere right around 27 psi.
