From aluminum to zinc, the HI83200 benchtop photometer offers 44 measurement methods for different key water quality parameters. This photometer features an advanced optical system that uses special tungsten lamps, narrow band interference filters, and silicon photodetectors to ensure accurate photometric readings every time. As a benchtop meter, the HI83200 operates on 12VDC supplied from an AC adapter. When portability is desired the meter can also operate on the internal rechargeable battery. The HI83200 uses a graphic backlit LCD that allows for an intuitive user interface. The meter offers a tutorial mode that gives a step-by-step procedure for performing a measurement. The result obtained can be displayed in various chemical forms based on the user’s preference. For tracking of data, results can be logged and then exported to a Windows® compatible PC using the HI92000 software and HI920013 USB cable.
Backlit Graphic LCD Display – The HI83200 features a backlit graphic display with virtual keys and on-screen help to provide for an intuitive user interface.
Data Logging – Users can store up to 200 readings by simply pressing the dedicated LOG button. Logged readings are just as easily recalled by pressing the RCL button.
PC Connectivity – Logged readings can be quickly and easily transferred to a PC via USB using the HI92000 Windows®compatible software.
Result Conversion – Eliminates confusion by automatically converting readings to other chemical forms. Common conversions are available at the touch of a button.
On-screen Tutorial – With the tutorial function enabled, short guides relating to the current operation are displayed. At any stage in the setup or measurement process, the dedicated HELP button is also available to show contextual help.
Auto-shut off – Automatic shut off after 10 minutes of non-use when the meter is in measurement mode and operating on the internal rechargeable battery.
Battery Status Indicator – Indicates the amount of battery life left.
Built-in Timer – Display of time remaining before a measurement is taken. Ensures that 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.
Cuvette Cover – Aids in stopping stray light from affecting measurements.
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 Measure – Appropriate unit of measure is displayed along with reading.
Advanced Optical System
The HI83200 features 44 different methods that can be measured using ready-made liquid or powder reagents. When the appropriate reagent is used for a selected method, the reaction between the reagent and the sample causes a color change; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. A narrow band interference filter allows the relevant wavelength of light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
