The Hanna Instruments-96769 portable photometer is for the measurement of anionic surfactants. Present in waters and wastewaters, surfactants are discharged via aqueous waste from households, industrial laundering, and other cleansing operations.
Hanna Instruments-96769 Anionic Surfactants Portable Photometer
Hanna’s portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL CheckTM feature utilises ready-made, NIST traceable standards to verify both meter validation and calibration. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.

About anionic surfactants
Generally present in detergents and other cleaning agents, a surfactant molecule consists of a strongly hydrophobic group and a strongly hydrophilic group, permitting solubility in both aqueous and non-aqueous media. When the hydrophilic group is negatively charged, it is deemed an anionic surfactant; when the hydrophilic group is positively charged, it is deemed a cationic surfactant.

Key features of the Hanna Instruments-96769

CAL Check – Allows for performance verification and calibration of the meter using NIST traceable standards.
GLP – Review of the last calibration date.
Auto-shut off – Automatic shut off after 10 minutes on non-use when the meter is in measurement mode - prevents battery wastage in case the meter is accidentally left on.
Battery status indicator – Indicates the amount of battery life left.
Built-in timer – Display of time remaining before a measurement is taken. Ensures all readings are taken at the appropriate reaction intervals for the test being performed.
Error messages – Messages on display alerting to problems including no cap, high zero, and standard too low.
Cooling lamp indicator – To maintain the desirable wavelength to be used for absorbance, it is necessary to ensure components are not overheated from the heat generated by the tungsten lamp. Each photometer is designed to allow a minimal amount of time for components to cool. The cooling lamp indicator is displayed prior to a reading being taken.
Units of measurement – Appropriate unit of measure is displayed along with reading.
