What Can the HI83314 Measure?

The HI83314 supports multiple methods for analysing key water and wastewater parameters. Depending on the selected method and compatible reagents, these include:


  • Chemical Oxygen Demand (COD)
  • Ammonia
  • Free and total chlorine
  • Total iron
  • Nitrate and nitrite
  • Total nitrogen
  • Reactive, acid-hydrolysable and total phosphorus
  • pH by photometric method
  • pH and temperature using a compatible digital electrode

The instrument also includes an absorbance measurement mode for checking optical performance with suitable standards or developing concentration-versus-absorbance curves using appropriate methods.



Always check the individual method specifications, measurement range and reagent requirements before selecting a test.

COD Measurement Ranges

Chemical Oxygen Demand is an important parameter in water and wastewater analysis. The HI83314 offers three principal COD measurement ranges when used with the appropriate 16 mm reagent vials.

COD Range Measurement Range
Low Range 0–150 mg/L as O₂
Medium Range 0–1,500 mg/L as O₂
High Range 0–15,000 mg/L as O₂

The appropriate range depends on the expected COD concentration in the sample. Selecting the correct reagent method is important for obtaining useful results.



COD testing requires a digestion stage using a compatible heating reactor. The HI83314 measures the prepared sample photometrically; the reactor and reagents must be selected separately where they are not already available.

How Does a COD Photometer Work?

Chemical Oxygen Demand measures the oxygen equivalent required to chemically oxidise substances in a water sample. It is commonly used in wastewater monitoring to assess the level of oxidisable material and to help evaluate wastewater treatment performance.


With the HI83314, the selected sample is prepared using the appropriate COD reagent method. Where required, the sample undergoes controlled heating in a digestion reactor before photometric measurement.


The instrument measures the prepared sample using light at the wavelength specified for the selected method and calculates the corresponding COD concentration.



Routine COD testing can help laboratories and wastewater treatment operators monitor changes in sample quality and assess treatment processes. Results should be interpreted alongside the relevant sampling procedures, operating requirements and other water quality measurements.

Advanced Optical Technology

The HI83314 incorporates an optical system designed to support reliable, repeatable photometric measurements.


LED light source and optical filters

The instrument uses LED light sources with narrow-band interference filters to provide the wavelengths required for its programmed measurement methods.


Reference detector

An internal reference detector monitors the light source and helps compensate for changes in light intensity during measurement.


Focusing optics

A focusing lens directs light passing through the sample cuvette towards the detector. This optical arrangement helps reduce the influence of certain cuvette imperfections on the measurement.


Together, these features support consistent results when the instrument is operated using the appropriate sample preparation and measurement procedure.


pH and Temperature Measurement

As well as photometric analysis, the HI83314 can function as a laboratory pH meter when connected to a compatible digital pH electrode.

The electrode measures pH and temperature, with automatic temperature compensation for pH measurements. Calibration information is stored in the compatible digital electrode, and the instrument provides calibration checks to help identify potential electrode or calibration issues.

This integrated capability allows users to carry out photometric water analysis and electrode-based pH measurements using one benchtop instrument.

Please note: The digital pH electrode is not included as standard and must be purchased separately if required.


Data Logging and USB Connectivity

Keeping measurement records is an important part of laboratory and wastewater monitoring procedures. The HI83314 can store up to 1,000 photometric and pH readings for later retrieval.


Users can add sample and user identification details to logged measurements and transfer records via USB for use on a computer or compatible flash drive. Data can be exported in CSV format for analysis using spreadsheet software.



These functions can help simplify routine record keeping and make it easier to review previous measurements.

Applications of the HI83314

The HI83314 is designed for laboratory and professional water analysis, including:

  • Wastewater treatment: Monitoring COD and selected nutrient-related parameters.
  • Industrial wastewater: Analysing wastewater from manufacturing and industrial processes.
  • Municipal wastewater: Supporting routine testing of wastewater quality and treatment performance.
  • Environmental laboratories: Testing water samples using suitable programmed methods.
  • Laboratory water analysis: Measuring multiple parameters with one benchtop photometer.
  • Nutrient removal monitoring: Measuring selected nitrogen and phosphorus parameters relevant to wastewater treatment.

The suitability of the instrument depends on the specific parameters, concentration ranges and methods required by the application.

Reagents and Accessories

To configure a complete COD testing system, check which reagents and accessories are required for your intended measurements.

Depending on your existing laboratory equipment and chosen methods, you may need:


  • Compatible COD reagent vials for the required measurement range.
  • A suitable digestion reactor for methods requiring controlled heating.
  • Compatible reagents for additional water quality parameters.
  • A compatible digital pH electrode for pH and temperature measurement.
  • Appropriate standards and accessories for performance verification.
  • 

Important: Reagents and the digital pH electrode are not included as standard. Confirm the required accessories and reagent compatibility before ordering.

Five Top Features

  • 1. High Efficiency LED Light Source

    An LED light source offers superior performance compared to a tungsten lamp. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce very little heat, which could otherwise affect the optical components and electronic stability. LEDs are available in a wide array of wavelengths, whereas tungsten lamps are supposed to be white light (all wavelengths of visible light) but actually have a poor blue/violet light output.

  • 2. High Quality Narrow Band Interference Filters

    The narrow band interference filter not only ensure greater wavelength accuracy (+/- 1 nm) but are extremely efficient. The filters used allow up to 95% of the light from the LED to be transmitted as compared to other filters that are only 75% efficient. The higher efficiency allows for a brighter, stronger light source. The end result is higher measurement stability and less wavelength error.

  • 3. Reference Detector for a Stable Light Source

    A beam splitter is used as part of the internal reference system of the HI-83300 photometer. The reference detector compensates for any drift due to power fluctuations or ambient temperature changes. Now you can rely on a stable source of light between your blank (zero) measurement and sample measurement.

  • 4. Large Cuvette Size

    The sample cell of the HI-83314 fits a round, glass cuvette with a 25 mm path length. Along with the advanced optical components, the larger size of the cuvette greatly reduces errors in rotation from the indexing mark of the cuvettes. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.

  • 5. Focusing Lens for Greater Light Yield

    Adding a focusing lens to the optical path allows for the collection of all of the light that exits the cuvette and focusing the light on the silicon photo detector. This novel approach to photometric measurements cancels the errors from imperfections and scratches present in the glass cuvette eliminating the need to index the cuvette.
