Description
The HI97106 is a portable photometer for chemical oxygen demand (COD) measurement, waterproof and with an advanced optical system that uses a light-emitting diode (LED) and a narrowband interference filter to ensure accurate and repeatable readings. The optical system is completely sealed against dust, dirt and water.
Main features:
No warm-up time: Ready to measure instantly.
Tutorial mode: Step-by-step instructions for easy preparation and measurement.
CAL Check™: Verification and calibration of performance at any time.
The meter has a unique positive locking system that ensures that the vials are always placed in the same position in the holder, ensuring repeatability of measurements.
With the CAL Check functionality, users can validate the instrument’s performance at any time. Hanna Instruments’ CAL Check cuvettes are certified with NIST-traceable reference instruments.
The built-in tutorial mode guides the user step-by-step through the measurement process, including sample preparation, required reagents, and exact quantities.
Features and benefits:
Sophisticated optics: Ensures accurate and reliable measurements.
Waterproof design: IP67 rated housing that floats on water.
Backlit LCD display: 128 x 64 pixel display simplifies the user interface.
Meter validation with CAL Check certified cuvettes.
Tutorial mode: Guided support throughout the measurement process.
Automatic Data Logging: Facilitates the storage of water analysis results.
Battery indicator and automatic shut-off: The meter automatically turns off after 15 minutes of inactivity to conserve battery.
Compact dimensions:
Size: 142.5 mm (5.6″) x 102.5 mm (4″) x 50.5 mm (2″).
Ideal for field or laboratory measurements.
Measurement procedure:
Switching on the equipment:
Press the power button. The screen will display the main menu.
Sample Preparation:
Fill a bucket with the water sample to the indicated mark.
Add the COD-specific reagents (according to the manufacturer’s instructions).
Mix the contents well.
Placement of the vial on the photometer:
Wipe the outside of the bucket with a lint-free cloth to remove fingerprints or water droplets that may affect the reading.
Be sure to align the reference marks on the cuvette and meter holder for correct positioning.
Team zero:
If necessary, use a bucket of distilled water and no reagents as a target.
Insert this cuvette into the light meter holder.
Press the calibration button (ZERO). The display will show “0.00” mg/L (ppm) COD.
Sample Measurement:
Replace the target bucket with the prepared sample bucket.
Press the READ button.
The photometer will perform the measurement and display the result in mg/L (ppm) directly on the display.
After measurement:
Cleaning:
Wash the cuvettes with distilled water to avoid reagent residues that may interfere with future measurements.
Dry the trays carefully.
Data logging:
If you need to save the results, use the automatic data logging feature on the photometer.
Off:
The device shuts down automatically after 15 minutes of inactivity, but you can turn it off manually if you will no longer use it.
Important tips:
Always use reagents compatible with the HI97106 model.
Avoid scratching the trays, as this could affect the accuracy of the readings.
Store the light meter in a dry place away from direct sunlight.
