HANNA Freshwater Ammonia Medium Range Checker® HC Reagents - HI715-11

The HANNA Freshwater Ammonia Medium Range Checker HC Calibration Check Set (HI715-11) is the replacement test reagents for the Ammonia Medium Range Checker HC - HI-715

This high-quality set of calibration standards is manufactured in our state-of-the-art facility and comes supplied with a Certificate of Analysis. The Certificate of Analysis provides the lot number, reference values and expiry date to provide traceability.

It is specifically designed for the measurement of ammonia in the range of 0.00 to 9.99 ppm (mg/L). Based on the Nessler method, which is a well-established and reliable method for the measurement of ammonia.

The Hanna Ammonia Medium-Range Checker HC bridges the gap between simple chemical test kits and professional instrumentation.
Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in colour.
Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars.
The Hanna Ammonia Medium-Range Checker HC uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

How to Use with Ammonia Medium Range Checker HC:

1. Fill a clean vial with 10 mL of sample water.
2. Add 4 drops of HI715A reagent to the vial.
3. Swirl the vial gently for 30 seconds.
4. Add 4 drops of HI715B reagent to the vial.
5. Swirl the vial gently for 30 seconds.
6. Close the vial and place it in the Checker HC.
7. Press the READ button.
8. The ammonia concentration in ppm (mg/L) will be displayed on the screen.

The Checker HC is simple to use

1. 'Zero' the Checker HC as required in specific procedure
2. Place the reagent vial into your Checker HC
3. Press the button and read the results. Compare against the accuracy statement found on the Certificate of Analysis.
