HI-97721
The HI-97721 is an advanced portable photometer for the measurement of High Range Iron in water.
This meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
Adaptation of Standard Methods for the Examination of Water and Wastewater, 23rd edition, 3500-Fe B, Phenanthroline Method.
About the HI-97721 Iron HR portable photometer
- Range: 0.00 to 5.00 mg/L (as Fe)
- Advanced LED optical system – 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.
- CAL Check™ - Validate the performance of the instrument at any time and apply a user calibration using CAL Check cuvettes made with NIST traceable standards. The CAL Check screen guides the user step-by-step through the validation process and user calibration.
- Auto logging
- GLP – Review of the last calibration date
- On-screen tutorial mode with animations – the built in tutorial mode guides users step-by-step through the measurement process.
- Waterproof and floating IP67 case
- Auto-shut off – Automatic shut off after 15 minutes of inactivity and 30 minutes before a read measurement.
- Battery status indicator – Indicates the amount of battery life left.
- Built-in 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.
- Error messages – Messages on display alerting to problems including on cap, high zero, and standard too low.
- Unit of measure – Appropriate unit of measure is displayed along with reading.
About Iron
Iron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents. The iron concentration in water needs to be monitored because it becomes harmful above certain levels.
In domestic water, for instance, iron can unpleasantly alter the taste, stain laundry, damage kitchenware, and favour the growth of certain bacteria.
Iron is also an indicator of ongoing corrosion in water cooling and heating systems.
Moreover, iron is normally monitored in mining wastewater to avoid contamination.
