In stock
The HI83224 COD Meter and Multiparameter Photometer for chemical oxygen demand (COD) and specific ion measurement combines accuracy and ease of use in an ergonomic benchtop design. This meter is one of the most versatile photometers in the market, offering 15 measurement methods for different parameters including COD using ready-made liquid or powder reagents. The HI83224 has many advanced features including barcode recognition of sample vials, a graphic LCD to display various chemical forms, and a step-by-step tutorial mode for inexperienced users.

From ammonia to phosphorus, the HI83224 benchtop photometer measures 15 measurement methods for different key water quality parameters in addition to chemical oxygen demand (COD) in 3 different ranges. The HI83224 features a barcode reader that can be used for barcoded sample vials. The reader scans each vial and automatically identifies the method and range, eliminating potential errors and simplifying the testing process. 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 HI83224 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<sup>&reg;</sup> compatible PC using the HI92000 software and HI920013 USB cable.

 

Features at-a-glance

 

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<sup>&reg;</sup> 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.

 

On-screen Features

 

Method Selection

Users can easily select any one of the 15 measurement methods via the dedicated METHOD button. 

Data Logging

Up to 200 measurement readings can be logged and recalled for future use. 

Log Recall

Logged data can easily be recalled and the chemical form can be converted at the touch of a button.

 

Advanced Optical System

The HI83224 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.
