Latest spectrophotometer Portable anionic surfactant measuring device (for fresh water)
Hanna Instruments JAPAN
About This Product
■Latest spectrophotometer series
・Measure anionic surfactants with a portable digital spectrophotometer (0.00-3.50 mg/L)
・Special reagents are used for measurement. Numerical verification and calibration of the main unit can also be performed using a validator (standard solution set). This ensures high accuracy and reliability.
■The conventional HI 96769 is a powered-up model with improved performance.
・Advanced optical system with beam splitter improves reproducibility and stability
- Light source changed from conventional tungsten lamp to LED. Demonstrates excellent performance
・Navigation function for measurement procedures
・Remaining battery power (%) is always displayed on the screen
・Time setting possible (year, month, day and time)
・Equipped with backlight function for easier viewing
■Applications
Surfactants present in water and wastewater are mainly discharged from household and industrial water sources. Surfactant molecules in detergents and other cleaning agents consist of strong hydrophobic groups and strong hydrophilic groups, and are soluble in both aqueous and non-aqueous media. When the hydrophilic group has a negative charge, it is considered an anionic (anionic) surfactant, and when it has a positive charge, it is considered a cationic (cationic) surfactant. This instrument uses USEPA method 425.1 and MBAS (methylene blue) method to measure the concentration of anionic surfactants. (SDBS: as sodium dodecylbenzenesulfonate) When methylene blue reagent is added to a sample containing an anionic surfactant, the sample turns blue and the color becomes darker as the concentration increases.
■Hannah's unique verification and proofreading functions
By using Hanna's original validator (standard solution set), it is possible to verify whether the values are within the standard values and calibrate if they are outside the acceptable range. (Calibration is a function that corrects discrepancies in numerical values on the main unit.) Since it can be performed by the customer at any time, high accuracy and reliability can always be maintained.
■Advanced optical system
Adopts an advanced optical system that incorporates the same beam splitter as the HI 833 series of multi-spec tabletop absorption photometers. Increases reproducibility and stability
■Waterproof & data storage
The main body case has a waterproof function of IP67, and the glass cell insertion part also uses a plastic holder. Compared to the conventional HI 96 series, it has improved waterproofness and durability for peace of mind. You can rest assured that up to 50 measured values are automatically saved. You can clearly see the measurement date and time using the details button.
■Easy to use compact size
The width is 142mm, making it more compact than the conventional HI 96 series.
