Description
Hydrazine photometer HI97704 is a dedicated portable meter for photometric determination of hydrazine from 0 to 400 µg/L (as N2H4). The method follows ASTM Manual of Water and Environmental Technology D1385 using p-dimethylaminobenzaldehyde; resolution is 1 µg/L with accuracy of ±4 % of full scale at 25 °C. Measurement is performed at 466 nm with an LED source and silicon photocell detector. The sealed optical path resists dust, dirt and water from outside, while the cuvette holder ensures consistent placement of the round 24,6 mm cells (22 mm internal) for repeatable readings.
This article is part of Photometers & spectrophotometers, in Spectroscopy & photometry.
Hydrazine is widely used as an oxygen scavenger in high-pressure heating systems to limit scale and corrosion without adding dissolved solids, and also appears in fuel cells, metal recovery and chemical synthesis. This HI97xxx-series instrument from manufacturer Hanna Instruments offers CAL Check™ readiness for NIST-traceable verification, a step-by-step tutorial mode, German menu guidance, GLP with last calibration date and time, automatic storage of the last 50 results, reaction timer, battery indicator and auto-off after inactivity. Operating range 0 to 50 °C, IP67, relative humidity up to 100 %. Powered by three 1,5 V batteries for more than 800 measurements without backlight. Device-only supply includes two capped cuvettes, plastic inserts, cleaning cloth, batteries, quality certificate and manual; reagents and CAL Check™ standards are ordered separately.

Questions about Hydrazine photometer: Range 0 to 400 ?g/L - meter only
What is this article?
Hydrazine photometer: Range 0 to 400 ?g/L - meter only is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
