Hanna HI 715 Ammonia Medium Range Checker/HI 715 Ammonia MR https://www.shopee.com/tridilab1809/hanna-hi-715-ammonia-medium-range-checker-hi-715-ammonia-mr HANNA HI 715 Medium Range Ammonia Colorimeter Checker. The HI 715 Checker HC (Handheld Colorimeter) is a simple, accurate and cost effective way to measure ammonia. Present in water as a component of the nitrogen cycle, ammonia is excreted from animals and other organisms such as heterotrophic bacteria, actinomycetes, and fungi during the metabolism of proteins and amino acids. Generally present in small quantities in unpolluted waters, higher levels indicate organic pollution, and is toxic to aquatic life. Designed as a more accurate alternative to chemical test kits, the HI 715 provides quick, accurate results in a few easy steps. Specification : Range : 0.00 to 9.99 ppm NH-N. Resolution : 0.01 ppm. Accuracy @ 25oC/77oF : plusmin.0.05 ppm plusmin.5% of reading. Light Source : LED @ 470 nm. Light Detector : silicon photocell. Method : adaptation of the ASTM Manual of Water and Environmental Technology D1426-92, Nessler Method. The reaction between ammonia and reagents causes a yellow tint in the sample.
