These portable photometers are designed with an innovative optical system that offers superior performance in accuracy, repeatability, and the amount of time that it takes to do a measurement.
These waterproof meters are extremely user friendly with a tutorial mode that walks the user graphically, step-by-step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys making operation of the meter very intuitive.
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. LEDs are available in a wide array of wave-lengths, whereas tungsten lamps have poor blue/violet light output.
Improved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.
The internal reference system of these 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 your blank (zero) measurement and sample measurement.
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.
Chosen parameter and method used is displayed along with the reading.
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.
The Hanna positive-locking system ensures cuvettes are placed into the holder in the same position every time.
Advanced features such as CAL Check™ to verify performance, GLP for last calibration date, setup and ability to see all accessories used with the meter.
Setup options for meter personalization include date and time format, language, and enabling the tutorial mode.
Choice of powder or economical, easy-to-use, liquid reagents.
Backlit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.
The built in Tutorial mode guides users step-by-step through the measurement process.
Displays time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate intervals for the test being performed.
CA dedicated help key provides informational help relating to the current meter operation, and can be used at any stage in the setup or measurement process.
The casing offers IP67 waterproof protection and floats.
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.
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.
Users can select the use of powder reagents supplied in packets or the use of liquid reagents supplied in a dropper bottle.
Allowing time for the reagents to react is primarily important 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.
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.
These photometers are designed with a backlit, graphic LCD, virtual keys, a battery status indicator, and error messages. Users will find the interface intuitive and easy to read.
Good Laboratory Practice (GLP) shows the date and time of the last user calibration.
Log and recall the last 50 measurements.
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.
Tutorial mode provides step-by-step instructions to guide a first time user to preforming a measurement correctly.
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.
These meters use three AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.
