Description
Hydrazine photometer HI97704C is a portable, battery-powered instrument for measuring hydrazine from 0 to 400 µg/L (as N2H4). It applies the p-dimethylaminobenzaldehyde method in line with ASTM D1385, reading the colour development at 466 nm with 1 µg/L resolution and accuracy of ±4 % of full scale at 25 °C. An LED and narrow-band optical system sealed against dust, dirt and external moisture, together with a fixed cuvette seating geometry, support accurate and repeatable fieldwork and laboratory checks on round 24,6 mm cuvettes.
This article is part of Photometers & spectrophotometers, in Spectroscopy & photometry.
Hydrazine serves as an oxygen scavenger in high-pressure heating circuits, helping prevent scale and corrosion without generating dissolved solids, and is also used in fuel cells, metal recovery and as an intermediate in agrochemical and pharmaceutical manufacture. From manufacturer Hanna Instruments, this HI97xxx-series meter includes CAL Check™ with NIST-traceable standards so users can verify performance and recalibrate on demand. Tutorial mode guides sample preparation and reagent amounts; German menus, GLP calibration recall, storage of the last 50 readings, built-in timer, battery status and auto-off simplify daily use. IP67, 0 to 50 °C, three 1,5 V AA batteries, more than 800 measurements without backlight. Delivered in a carrying case with two capped cuvettes, inserts, CAL Check™ standards, scissors, cleaning cloth, batteries, quality certificate and manual; reagents are ordered separately.

Questions about Portable Photometer for Hydrazine with CAL Check standards
What is this article?
Portable Photometer for Hydrazine with CAL Check standards 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.
