Process management and quality control
Usage
①
Use a pipette (small) to transfer 0.2 mL of test water into a dedicated cup.
②
Add 1.5 mL of K-1 reagent to the pipette (large).
③
Cut off the K-2 reagent (in small bags) and add it to a dedicated cup.
④
Cover the lid and shake it thoroughly to dissolve it.
⑤
Let it stand for 5 minutes. (Shake and mix 1-2 times along the way.)
⑥
Pull out the wire at the top of the tube.
