Overview
HI781 Nitrate LR Tintometer is a photometer instrument for the measurement of low-concentration nitrate in water samples. Nitrate, as a common water pollutant, can easily lead to increased soil and groundwater concentration in agricultural fertilizer use. The instrument is suitable for environment monitoring, water quality testing and agriculture. It helps monitor and control nitrate concentration in water to protect the environment and human health.
Features
1. LED high-quality Illuminant system, compared with traditional tungsten lamps, has better performance and higher luminous efficiency, can provide the best stable Illuminant with less energy, and can ignore the influence of its own heat on electronic stability
2. CAL CHECKTM function that allows performance verification and calibrating using NIST traceability standards, verifying reading accuracy by simulating specific Absorbance values with NIST Linear dispersion calibration sets
Principle
When using a nitrate LR Tintometer, a water sample is mixed with a chemical Reagent to form a specific reaction product whose concentration is proportional to the nitrate concentration. Optical inspection measures the concentration of the product to determine the nitrate concentration in the water sample.
Applications
Aquaculture, aquariums, swimming pools, spas
Steps
1. Mix Water Sample with Chemical Reagent to Form Reaction Product
2. Tintometer Optical inspection measurement product concentration
3. Determine nitrate concentration according to product concentration
Notice
• Suitable for measurement of low concentration nitrate in the range of 0.00 to 5.00ppm
• Measurement accuracy of +/- 0.25ppm +/- 2% reading @25 ° C
• Colorimetry, Nitrate Reacts with Reagent to Produce Pink/Purple
Developed specifically for processing seawater samples
• Use 1.5V AAA alkaline battery
• Automatic shutdown when not in use for 10 minutes
• Working environment 0 to 50 ° C, maximum 95% relative humidity without condensation
