The provided standard colors display nitrate ion values on the top row and nitrate nitrogen values on the bottom row. You can use any of them according to the measurement purpose.
Main applications
Wastewater management
Process management and quality control
Agriculture (Fertilization Management)
Usage
①
Pull out the wire at the top of the tube.
②
Pinch the lower part of the tube with your fingers and squeeze out the air inside, with the hole facing upwards.
③
Put the hole directly into the water for testing, release the fingers holding it, and wait until about half of the water is sucked in.
Gently shake and mix 5-6 times, being careful not to let the liquid leak out.
④
After 5 minutes, place the tube on the standard color for color comparison.
0mg/L cannot show color and will appear colorless.
❶
Put 30 mL of test water into a beaker and add a separately available nitric acid pre-treatment agent (NO) for measurement3-RA) proceed.
❷
Heat with a heater device and boil for about 2 minutes.
❸
Reduce to indoor temperature. If the amount of water to be tested decreases, add purified water to 30mL. Start measuring nitrate from ①.
