Details

From ammonia to phosphorus, the HI83214 benchtop photometer offers 15 measurement methods for different key water quality parameters including chemical oxygen demand (COD) in 3 different ranges. 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. The HI83214 uses a graphic backlit LCD that allows for an intuitive user interface, offering 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.

 

Features at-a-glance

Backlit Graphic LCD Display - The HI83214 features an adjustable 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 LOG key. Logged readings are just as easily recalled by pressing the dedicated RCL button. Stored data includes parameter, test results, sample number, lot number, instrument ID, date and time.

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.

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.

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 HI83214 features 15 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.
