Hanna Instruments COD/Multiparameter Photometer

Need Trafo Step Down

Barcode Recognition - Automatic recognition of bar coded samples is an exciting feature of the HI83224. This advanced meter scans each vial inserted into the vial holder and automatically identifies the sample method and range. The barcode has four digits: the first two digits are for parameter identification and the second two digits are for reagent lot ID. Vials for different methods can be distinguished by a barcode printed on the vial and the cap color - the barcodes for different methods are shown in the table below. For parameters that don’t use a barcoded reagent, the vials supplied with the instrument can be used.
Vial Rotation - During the measurement phase of the analysis, the state-of-the-art vial rotator spins the vial to identify the method via the barcode, then rotates while taking a number of absorbance readings. The instrument then converts the readings to concentration units and displays the result on the easy to read screen.
Improved Accuracy - Using the "average" function further improves reading accuracy. When enabled in the setup menu, the instrument takes 180 absorbance readings through the vial as it rotates. Each individual reading represents a measurement through a new optical path. Averaging the absorbance readings minimizes errors due to vial inconsistencies.
Method Verification - A dedicated METHOD CHECK button is available to quickly verify the vial barcode, eliminating the potential for vial confusion or incorrect sample readings.
Backlit Graphic LCD Display - The HI83224 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 barcode error, wrong vial, and different reagent lot.
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.
