Description
Photometer for chloride is a dedicated portable HI97xxx-series meter for photometric chloride determination from 0,0 to 20,0 mg/L as Cl⁻. Resolution is 0,1 mg/L, with accuracy at 25 °C of ±0,5 mg/L ±6 % of reading. The method is adapted from the mercury(II) thiocyanate procedure. An advanced optical system combines an LED, a narrow-band interference filter at 525 nm and a silicon photocell in a housing sealed against dust, dirt and external water; cuvettes lock into a fixed position for reproducible optics. Chloride is a major inorganic anion in water and wastewater and is monitored in boilers and cooling towers to limit corrosion, in drinking water for aesthetic and taste reasons, and in agriculture where elevated natural levels can harm plants. CAL Check™ with NIST-traceable standards allows on-demand performance verification and recalibration. A tutorial mode details sample preparation and reagent quantities; GLP stores last calibration date and time, the last 50 readings are saved automatically, and timer, battery status and auto power-off support field and lab work. Rated IP67 for 0 to 50 °C, the Hanna Instruments kit includes two capped cuvettes, plastic inserts, CAL Check™ standards, scissors, cleaning cloth, three 1,5 V batteries, quality certificate and manual in a transport case; reagents are ordered separately.

Questions about Portable Photometer for Chloride with Check standards
What is this article?
Portable Photometer for Chloride with 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 Instruments de précision.
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.
Which category should I open next?
The category is Spectroscopy & photometry. The sub-category is Photometers & spectrophotometers. The catalogue is Instruments de précision.
Shelves beside this one are Refractometers & polarimeters and Lamps, cuvette holders & accessories.
What should I check before I order?
