The HI96728 portable photometer is for the measurement of nitrate as nitrogen. Hanna's portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check feature utilizes ready-made, NIST traceable standards to verify both meter validation and calibration.
- CAL Check - Allows for performance verification and calibration of the meter using a CAL Check NIST traceable secondary standard.
- GLP - Records the date of the last user calibration performed.
- Built in timer - Ensures the appropriate reaction time is used for the chemical reaction. At the end of the timer the meter will automatically take the reading.
- Indexing indent on meter - The meter has an indent that allows for a lock and key fit with the cuvette cap.
- Cooling Lamp Indicator - It is necessary to maintain a consistent temperature of the optical components in order to maintain a narrow wavelength band of light.
- Error messages - Messages on display alerting to problems including no cap, over range and under range readings, and light source error.
- Auto-shut off - Automatic shut off after 10 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally not turned off.
- Battery status indicator
