Introduction
HI781 Nitrate LR (Low Range) Colorimeter is an instrument used to measure the nitrate concentration in water samples. It is suitable for measuring low concentrations of nitrate. Nitrate is a common water contaminant, especially in agriculture, where the use of chemical fertilizers can lead to increased nitrate concentrations in soil and groundwater. The HI781 Nitrate LR Colorimeter can also be used in environmental monitoring, water quality testing and agricultural fields to help people monitor and control the concentration of nitrate in water bodies to protect the environment and human health.
Instructions
With a Nitrate LR Colorimeter, a water sample is typically mixed with a chemical reagent to form a specific reaction product. The concentration of this product is directly proportional to the nitrate concentration in the water sample. A Colorimeter then optically measures the concentration of this product to determine the concentration of nitrate in the water sample.
Features
LED high-quality light source system. Compared with traditional tungsten lamps and other light sources, LED light sources have better performance and higher luminous efficiency. They can use less energy to provide the best and stable light source. LEDs can ignore the heat they generate. , because higher heat can affect the stability of electronic products.
CAL CHECKTM function, HANNA's carefully designed CAL CheckTM function allows performance verification and calibration of the instrument using NIST traceable standards; CAL CheckTM NIST curve calibration set is used to simulate specific absorbance values ââat each wavelength to verify the accuracy of subsequent readings sex.
Application scope
Aquaculture, aquarium, swimming pool, SPA and other industries.
Single parameter measurement items: ammonia nitrogen, free chlorine, total chlorine, nitrite, fluoride ions, alkalinity, seawater alkalinity, etc.
