Hanna Instruments HI-93715-03 Ammonia Medium Range Reagent, Nessler Method 300 tests
The HI-93715-03 is a reagent for the colorimetric determination of ammonia. There are enough reagents for 300 tests and for use with Hanna’s compatible benchtop and portable photometers.
The HI-93715-03 are high quality, pre-measured reagents that allow users to achieve fast and accurate colorimetric measurements.
This reagent provides enough to do 300 tests.
Range: 0.00 to 10.00 mg/L
Benefits highlighted:
- Pre-made reagents for ease of use
- Prepared with high purity chemicals
- Marked with expiry date and lot number for traceability
These reagents follow the Nessler Method in which the reaction between ammonia and the reagent causes a colour change in the sample. The intensity of colour is determined by a compatible photometer. The concentration, based upon the meter in use, will be displayed in mg/L (ppm) as ammonia (NH3) or ammonia nitrogen (NH3-N). These reagents are designed to be used with samples that have an expected range of 0.00 to 9.99 mg/L ammonia.

The HI-93715-03 Ammonia, medium range reagent is suitable for use with the HI-96715 portable photometer, the HI-83200-02 and HI-83099-02 multi-parameter bench photometer, and other meters where specified.
About Ammonia
Present naturally in surface and waste waters, ammonia mainly results from the deamination of organic nitrogen-containing compounds and hydrolysis of urea. Ammonia may also be present from water treatment processes that utilise chloramines for disinfection, where ammonia is added to the water to react with chlorine. Ammonia is less likely to appear in groundwater due to adsorption to soil particles.
