HI97712 is an advanced portable photometer for the measurement of aluminium. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
- No warm up time before taking a measurement
- Tutorial mode for step-by-step instructions
- Uses either powder or cost saving liquid reagents
Using the HI93712 ready made reagents a user can accurately determine the concentration of aluminum in samples within a 0.00 to 1.00 mg/L (ppm) range. The HI97712 offers many advanced features including the exclusive CAL Check™ function for performance verification and calibration of the meter.

Details
The HI97712 portable photometer is for the measurement of aluminum. 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 for meter validation and calibration. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.
Features at-a-glance
Waterproof casing– IP67 water protection, floats
Advanced LED optical system– LEDs have a higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.
CAL Check™ – Allows for performance verification and calibration of the meter using NIST traceable standards.
GLP – Review of the last calibration date.
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 left on.
Auto logging – Log and recal the last 50 measurements.
Auto off protection– these meters use three AAA 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.
Dedicated HELP– a dedicated Help KEY provides infomration relating to the current meter operation, and can be used at any stage in setup or meassurement process to show contextual help.
Battery status indicator – Indicates the amount of battery life left.
Built-in reaction timer – Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.
Intuitive dot matrix display- these photometers are designed with a backlit, graphic LCD. With virtual keys, a battery status indicator, and error messages. Users will find the interface intuitive and easy to read.
On screen tutorial mode with animations– the built in Tutorial mode guides users step-by-step through the measurement process.
Multiple measurement methods- users can select the use of powder reagents supplied in packets or the use of liquid reagents supplied in a dropper bottle.
Error messages – Messages on display alerting to problems such as out of range, light low, light high, ambient temperature out of limits, and battery low.
Units of measure – Appropriate unit of measure is displayed along with reading.
- LED that generates very little heat
- 8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency.
- Reference detector that modulates the voltage to LED for consistent light output.
- A concave focusing lens that reduces errors from imperfections in the cuvette
Due to its vast occurrence in minerals, rocks and clays, aluminum is present in nearly all natural water as a soluble salt, colloid, or an insoluble compound. These forms of aluminum may also appear in treated water and wastewater due to its use during coagulation processes. When concentrations are greater than 0.2 mg/L, water will be colored, but cause no significant human health effects.
