Measuring steps:
1.2ml Pure water and 2ml to be measured solution respectively add different cod reagent tubes, tighten the lid, slowly shake the reagent tube solution, and the reagent pipe into the digestion instrument, under 165 ℃ digestion 20 minutes. (Hazard: The reagent tube contains concentrated sulfuric acid, please wear gloves when operating, such as if accidentally contacting the skin, please immediately with a large amount of water cleaning.
2. After the digestion is complete, the reagent tube is removed and placed in the test tube rack and cooled to below 80 ℃. (Warning: The digestion instrument and the reagent tube temperature are high, the operation attention does not scald.)
3. Shake the liquid again in the reagent tube.
4. The reagent tube is placed on the test-tube rack and continues to cool to room temperature, at which time it is prohibited to shake the reagent tube.
5. Press the "switch" key to boot, the screen in the middle of "IdLE" means that the boot is completed, and the instrument is in the standby state.
6. Open the detection of the bunker cover, to ensure that the 0 water sample test tube surface is clean, put it into the test bin, cover the cover, press the "0" key, the screen in the middle of the "0" to indicate that the adjustment 0 completed.
7. Open the cover, remove the 0 water sample, put in the water sample, and cover the cover.
8. By the "reading" key, the number displayed in the middle of the screen indicates the value of the water sample. (Unit:/)
9. When the test is finished, press the "switch" button to close the instrument.
