Nutrient Analysis Photometer$774.00
HI83325 is a compact, multiparameter photometer for use in the environmental lab or in the field. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. This meter has 9 different programmed methods measuring 8 key plant nutrient water quality parameters and also offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves. Plant nutrient-specific parameters include potassium, calcium, and magnesium. To save valuable laboratory benchtop space, the HI83325 doubles as a professional pH meter with its digital pH/temperature electrode input. Now one meter can be used for both photometric and pH measurements.
- Advanced optical system
- Digital pH electrode input
- Save valuable bench space with one meter that works both as a photometer and as a laboratory pH meter
- Absorbance measuring mode

Consistent and thorough monitoring of plant nutrients is essential to maintaining healthy growth and reproduction. This is easy with the HI83325, a comprehensive way to monitor vital plant nutrients such as potassium, calcium and magnesium. Required in large quantities, potassium plays a vital role in water uptake and enzyme regulation. Calcium helps to strengthen plant cell walls protecting against heat stress while magnesium helps build a strong immune system.
A digital pH electrode input allows the user to measure pH by a traditional glass electrode. The digital pH electrode has a built in microchip within the probe that stores all of the calibration information. Having the calibration information stored in the probe allows for hot swapping of pH electrodes without having to recalibrate. All pH measurements are automatically compensated for temperature variations with a built in thermistor located in the tip of the sensing bulb for fast and accurate temperature measurement.
The HI83325 offers an absorbance measuring mode that allows for CAL CheckTM standards to be used to validate the performance of the system. The absorbance mode allows the user to select one of the three wavelengths of light (420 nm, 466 nm, and 525 nm) to measure and plot their own concentration versus absorbance mode. This is useful for users with their own chemical method and for educators to teach the concept of absorbance by using the Beer-Lambert Law.
Two USB ports are provided for transferring data to a flash drive or computer and to use as a power source for the meter. For added convenience and portability the meter can also operate on an internal 3.7 VDC Lithium-polymer rechargeable battery.

Features and Benefits
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 CheckTM alerts user to potential problems during the calibration process
- Space saving having a pH meter and photometer built into one meter
- Up to 1000 photometric and pH readings can be stored by simply pressing the dedicated LOG button. Logged readings are just as easily recalled by pressing the RCL button
- Sample ID and User ID information can be added to a logged reading using alphanumeric keypad
- Logged readings can be quickly and easily transferred to a flash drive using the USB-A host port or to a computer using the micro USB-B port
- Data is exported as a .CSV file for use with common spreadsheet programs
Battery Status Indicator
- Indicates the amount of battery life left
- Photometric error messages include no cap, high zero, and standard too low
- pH calibration messages include clean electrode, check buffer and check probe
Backlit 128 x 64 Pixel Graphic LCD Display
- Backlit graphic display allows for easy viewing in low light conditions
- The 128 x 64 Pixel LCD allows for a simplified user interface with virtual keys and on-screen help to guide the user through use of the meter
Built-in Reaction Timer for Photometric Measurements
- The measurement is taken after the countdown timer expires.
- Countdown timer ensures that all readings are taken at the appropriate reaction intervals regardless of user for better consistency in measurements
- Hanna's exclusive CAL CheckTM cuvettes for validation of light source and detector
- Allows for the user to plot concentration versus absorbance for a specific wavelength for use with user supplied chemistry or for teaching principles of photometry
Units of Measure
- Appropriate unit of measure along with chemical form is displayed along with reading
- Automatically convert readings to other chemical forms with the touch of a button
- Aids in preventing stray light from affecting measurements
