The highly accurate optical system is sealed from outside dust, dirt and water with an exclusive positive-locking system to ensure that the cuvettes are placed into the holder in the same position every time.
With the CAL Check™ functionality, users can validate the performance of the instrument at any time and apply a user calibration (if necessary). Hanna Instruments CAL Check™ cuvettes are made with NIST traceable standards.
The built-in tutorial mode guides users step-by-step through the measurement process. It includes all steps required for sample preparation, the required reagents and quantities.
About the seven parameters
Bromine
Bromine is a powerful water disinfectant, particularly effective in hot water (treatment of pools and spas). Bromine can act as an alternative to chlorine.
The method for bromine is an adaptation of Standard Methods for the Examination of Water and Wastewater, DPD Method.
Chlorine
Chlorine is a widely used disinfectant. In order for it to be effective, the pH of the water should be less than 8.0. The method for chlorine is an adaptation of US EPA Method 330.5, DPD Colorimetric Method.
The method for pH is an adaptation of the Phenol Red Method.
Chlorine Dioxide
Chlorine Dioxide is a powerful and selective disinfectant used in water treatment across a broad pH range.
ide is an adaptation of Standard Methods for the Examination of Water and Wastewater, 18th Ed., 4500 ClO₂ D.
Hydrogen Peroxide
Hydrogen Peroxide is an environmentally friendly, broad spectrum disinfectant. The method for hydrogen peroxide is an adaptation of German Standard Methods for the Examination of Water and Wastewater DIN 38409-15.
Ozone
Ozone is a widely used disinfectant in the treatment of drinking water, wastewater and swimming pools. The method for ozone is the DPD Colorimetric Method.

Our advanced LED optical system features
- 8 nm narrow band interference filter that is accurate to ±1 nm and offers a 25% increase in light efficiency over conventional filters
- A reference detector that modulates the voltage to the LED for consistent light output
- A concave focusing lens that reduces errors from imperfections in the cuvette
High efficiency light source
LED light sources offer superior performance compared to tungsten lamps. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.
High quality filters
High tolerance optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received providing higher measurement stability and repeatability.
Stable light source
The internal reference system of Hanna photometers compensates for any drifts due to power fluctuations or ambient temperature changes. With a stable source of light, the readings are fast and reliable between blank (zero) measurements and sample measurements.
Greater light yield
A focusing lens collects all of the light that exits the cuvette, reducing errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.
Large cuvette size
The sample cell of these photometers 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. The cuvette holder features ridges to protect scratching of the optical path by the cuvette.
Key features
Method and parameter
Chosen parameter and method used is displayed along with the reading.
Multiple measurement methods
Method selection can be accessed by pressing the menu button and selecting Methods. Use the function keys to highlight the desired method.
Auto logging
Log and recall the last 50 measurements.
Built-in reaction timer
Waiting for the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users.
CAL Check™ functionality
Hanna’s exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards.
Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings. The CAL Check screen guides the user step-by-step through the validation process and user calibration.
GLP data
Good Laboratory Practice (GLP) shows the date and time of the last user calibration.
Setup options
Setup options for meter personalization include date and time format, language, and enabling the tutorial mode.
Auto-off protection
Supplied with 3 x standard AA batteries provides power 800 measurements to be taken. Our batter preserving auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.
Battery status indicator indicates the amount of battery life left.
Dedicated help
A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.
On-screen tutorial mode with animations
The built in tutorial mode guides users step-by-step through the measurement process.
Error messages
Messages appear on the display alerting to problems such as out of range, light low, light high, ambient temperature out of limits, and battery low.
