Set of 300 reagents for high range ammonia meter.

The HI-93733-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the Nessler Method in which the reaction between ammonia and reagents causes a yellow tint in the sample. By simply adding the reagents to the sample, the reaction between ammonia and reagents causes a yellow tint in the sample will take place. The intensity of colour is determined by a compatible photometer and the concentration will be displayed. The results will be displayed in ppm (mg/L) of ammonium (NH₄+) but can easily be converted to ammonia-nitrogen (NH₃-N) or ammonia (NH₃). These reagents are designed to be used with samples that have an expected range of 0.0 to 50.0 ppm ammonium.
