Hanna Instruments HI-97709C Portable Photometer for Manganese - High Range - with case & CAL Check standard
Manganese Photometer Kit complete with CAL Check Standards and accessories.
Contains the HI-97709 which is an auto-diagnostic portable photometer that has an advanced optical system. The photometer uses a Light Emitting Diode (LED) and a narrow band interference filter that allows for accurate and repeatable readings. Measures the manganese content in water samples in the 0.0 to 20.0 mg/L (ppm ).
Each HI-97709C is delivered in a rugged carrying case and is supplied with:
- Photometer - HI-97709 Manganese High Range
- Sample cuvette (2 pcs.)
- Sample cuvette cap (2 pcs.)
- Plastic stopper (2 pcs.)
- A ZERO - CAL Check Cuvette A
- HI97709B - CAL Check Cuvette B for Manganese High Range
- Cloth for wiping cuvettes
- Scissors
- 1.5V AA Alkaline batteries
- CAL Check standard certificate
- Instrument quality certificate

About the photometer
The HI-97709 meter measures the manganese content in water samples in the 0.0 to 20.0 mg/L (ppm). The method is an adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th Edition, Periodate Method.
The optical system is sealed from outside dust, dirt and water. The meter uses 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 are able to 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.
The HI-97709 photometer is a compact and versatile meter suitable for field or bench measurements, featuring a:
- Sophisticated optical system
- Meter validation using certified CAL Check cuvettes
- Tutorial mode guides the user step-by-step
- Auto logging
- Waterproof IP67, floating case
- GLP features
Optical system
The internal reference system (reference detector) of the HI-97709 photometer compensates for any drifts due to power fluctuations or ambient temperature changes, providing a stable source of light for your blank (zero) measurement and sample measurement.
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 wavelengths, 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.
A focusing lens collects all of the light that exits the cuvette, eliminating errors from cuvette imperfections and scratches, eliminating the need to index the cuvette.
