£348.20 (exc. VAT) £417.84 (inc. VAT)

The HI-96709 Manganese High Range Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the concentration of manganese within a 0.0 to 20.0 mg/L (ppm) range using the HI-93709-0 ready made reagents. The HI-96709 offers many advanced features including the exclusive CAL Check™ function used for performance verification and calibration of the meter.

  • CAL Check™ Validation and Calibration
  • Built-in Timer
  • Automatic Shut Off
  • Battery powered – Allows use away from a power source. Batteries are included with all battery operated products.

    Water Resistant – Can withstand temporary exposure to water, but should not be submerged or washed under running water.

    HI-96709 Manganese High Range Portable photometer information

    Hanna's extended description

    The HI-96709 portable photometer is for the high range measurement of manganese. 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. 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.

    Key features

    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. This feature ensures consistency across multiple users.

    Indexing indent on meter - The meter has an indent that allows for a lock and key fit with the cuvette cap. This ensures that the cuvette is indexed consistently (same position) in order to maintain the same path length for accurate results.

    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. This photometer has a cooling lamp indicator that is displayed for a short period of time before each measurement in order to allow the components to cool and obtain the highest accuracy possible.

    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 left on.

    Battery status indicator

      The instrument has a battery level indicator to display reaming life as follows:

    • 3 lines for 100% capacity
    • 2 lines for 66% capacity
    • 1 line for 33% capacity
    • Battery icon blinks when the capacity is less than 10%
    • Units of measure - Appropriate unit of measure is displayed along with reading

    Manganese explained

    Manganese is one of the most common metals present in nature and is used in many industrial applications, for example, the production of fertilisers and in the pharmaceutical industry.

    Manganese salts are also used in iron alloys (steel manufacturing) and non-iron alloys as it improves their corrosion resistance and hardness.

    The HI-96709 uses an adaptation of Standard Methods for the Examination of Water and Wastewater, 18th edition, periodate method to measure manganese concentrations of less than 20.0 mg/L (ppm) manganese. When the reagent is added to samples containing manganese, the sample will turn a violet hue; the greater the concentration, the deeper the colour. The associated colour change is then colorimetrically analysed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary colour, and the emitted radiation is dependent upon concentration. For manganese determination, a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in colour of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
