Accuracy, Efficiency, and Consistency

Innovative optical system

HI83300 family is designed with an innovative optical system that incorporates a beam splitter so that light can be used for absorbance readings and by the reference detector. The reference detector monitors the intensity of light and modulates when there is drift due to power fluctuation or the heating of the optical components. Each part has an important role in providing unparalleled performance from a photometer.

High efficiency LED light source

An LED light source offers superior performance as 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.

Quality narrow band interference filters

The narrow band interference filter not only ensures greater wavelength accuracy (±1 nm) but is also extremely efficient, allowing a brighter, stronger signal to be transmitted. The end result is increased measurement stability and less wavelength error.

Reference detector for a stable light source

A beam splitter is used as part of the internal reference system of the HI83300 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.

Large cuvette size

The sample cell of the HI83300 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.

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 innovative approach to photometric measurements cancels the errors from imperfections and scratches present in the glass cuvette eliminating the need to index the cuvette.




pH connectivity

Plugging in an electrode has never been easier; there are no alignment issues or broken pins. Any of our digital pH electrodes can be connected by a 3.5 mm input.

Dual power supply

Equipped with a rechargeable lithium ion battery, these meters can be portable for measurements on the move. Battery life lasts up to 500 photometer measurements or 50 hours of continuous pH measurements. The auto-off feature automatically shuts the meter off after 15 minutes of inactivity. A power supply can be plugged into the micro USB port at the back of the meter for benchtop use.

USB connectivity

Both the USB and micro USB port can be used to transfer data via flash drive or direct connection to a PC or MAC. Data is transferred as a CSV file.


Digital pH Electrode Input

Measure pH and temperature with a single probe. Good Laboratory Practice (GLP) to track calibration information including date, time, buffers used, offset and slope for traceability. pH CAL Check™ alerts user to potential problems during the calibration process. Space saving having a pH meter and photometer built into one meter.

Photometer Capabilities


Concentration measurement function

Users can access the menu of measurement methods with the simple press of a button. Low, medium, and high range methods of several parameters are available for users to obtain a high accuracy reading. Each method is assigned a concentration unit of measure. Parameters can be expressed in different chemical forms based on user preference.

Large cuvettes

Large cuvettes

The sample cell of these meters fits a round, glass cuvette with a 25 mm path length. 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. This cuvette size also provides a larger opening, making it easier for users to dispense ready-made liquid or powder reagents into the sample.

An affixed, light-blocking cover panel closes over the sample cell, reducing stray light from affecting any measurement readings.

pH measurement

pH measurement

The HI83300 family offers the ability to connect a digital pH electrode. Users can connect any sensor from our extensive line of digital pH electrodes. Whether a user requires a glass or plastic body, a spheric or conical tip shape, or the ability for safe use with food samples, our digital electrode offering is suitable for nearly everyone.

Absorbance measurement mode

Absorbance measurement mode

Users can select to calibrate and measure samples in absorbance mode for each wavelength used by the meter. This mode is a convenient way for users to develop their own calibration curves and measure samples with customized chemistries.

CAL Check™ functionality

CAL Check™ functionality

Hanna’s exclusive CAL Check feature allows for performance verification of the independent measuring channels. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify its accuracy.

Built-in reaction timer

Built-in reaction timer

Reaction time is of key importance when performing colorimetric measurements, which is why the built-in timer of the HI83300 is a key feature. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between measurements and users.

Data Management Capabilities

Data Management

Data management

The HI83300 family can store up to 1000 photometer and pH electrode readings, which can be logged by pressing the LOG key on the face of the meter. pH readings are logged along with comprehensive GLP (Good Laboratory Practice) information such as date, time, calibration buffers, and electrode offset and slope.

User ID and sample ID

An alphanumeric keypad can be used to enter sample ID and user ID to be stored with the measurement reading. The recall key allows the user to review the data along with the date and time that the reading was taken.

USB for data transfer

Two USB ports are provided for transferring data. One port allows the data to be transferred to a flash drive while the other USB is used for direct connection to a computer. All data is transferred as a .CSV file that can be used with many spreadsheet programs for documentation.
