Product Description

Hydrazine is a liquid chemical substance normally used in high pressure heating plants because of its properties as an oxygen inhibitor. It is added to avoid scaling and corrosion in the plant itself. Hydrazine reacts with dissolved oxygen to yield nitrogen and water, so that hydrazine has the advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used in tanks because it controls the growth of bacteria. Other hydrazine uses include: oxygen scavenger for water boiler feed and heating systems to prevent corrosion damage, energy source in fuel elements, reducing agent for the recovery of metals (copper, nickel and others), intermediate in insecticides, herbicides, explosives, plant growth regulators, pharmaceuticals, dyes, flame-retardants, polymerization catalysts and other chemical products, component of photo development. The HI 96704 meter measures the hydrazine content in water samples. The method is an adaptation of the ASTM manual of water and environmental technology, method D1385-88 for natural and treated water. Cal Check. User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. Range: 0 to 400 µgrams per liter. Resolution: 1 µgrams per liter. Accuracy: +/-3 percent FS. Light source: light emitting diode. Light detection: silicon photocell with narrow band interference filter at 466 nm. Battery type/life: 9V/approx. 40 hours of continuous use; auto-off after 10 minutes of non use. Environment: 0 to 50 degree celsius (32 to 122 degree fahrenheit); RH max 95 percent non-condensing. Measures 7-19/32" length by 4-3/32" width by 2-11/16" height. Method: adaptation of the ASTM manual of water and environmental technology, method D1385-88 for natural and treated water.
