Chemical Oxygen Demand Meter Introduction:

Chemical oxygen demand measurement meter is widely used in water quality monitoring in environmental protection,petroleum,chemical industries,health,etc..Chemical oxygen demand meter is applicable to analysis the COD (abbr. of Chemical Oxygen Demand) of groundwater, surface water,domestic sewage and industrial waste water.COD is to measure the amount of oxygen consumed in the process of organic pollutants oxidation by oxidant.

Our own product chemical oxygen demand measurement meter LH-C3 can also test ammonia nitrogen and total phosphorus in water.

LH-C + XC-200 

Chemical Oxygen Demand Meter Measurement:

COD TEST  

NOTE:Take the head of the reagent tube, and the reagent tube should be cleaned before put in the test hole.


Steps

Operation processes

Description

1

Estimate the COD value of the water sample 

2

Choose the reagent and add the tested water sample according to the corresponding  range.

 

COD:o-150mg/L(c11)

COD:100-1500mg/L(c12)

COD:1000-15000mg/L(c13)

 


1.take 2ml distilled water into a LR reagent tube(ZERO setting)
2.take 2ml water sample into another LR reagent tube.

1.take 2ml distilled water into a HR reagent tube(ZERO setting)
2.take 2ml water sample into another HR reagent tube.

1.take 2ml distilled water into a HR reagent tube(ZERO setting)
2. take 1.8ml distilled water into another HR reagent tube ,then add 0.2ml water sample.

★Note:C12 and C13 can use the same one zero setting tube.

★Danger:There    have concentrated sulfuric acid in the test tube,please wear gloves to operate.

3

Tighten the reagent tube cap , shake well and put into the reactor, heat for 20 minutes at 165  ℃.

★Caution: Hot

4

After reaction, take out the reagent tube , when cooled to 80 ℃ shake reagent tube again.

 

5

Place the reagent tube on the tube rack and continue to cool to room temperature. This procedure prevents the reagent tube from shaking.

★Note:The suspended matter needs to be completely precipitated

6

Press "ON/OFF" button to turn on the meter, press "SWITCH" button to select the required test item.

 

7

Open the detection cap,put it into the zero water sample reagent tube, cover the cap, press the "ZERO" button to zero setting.

★The tube wall should be cleaned.

8

Take out the zero water sample reagent tube, put in the water sample reagent tube    and cover the cap.

★Under the c13 , when displayed as XXX mg/L, the detection value is XXX00mg/L.

9

Press "READ"button.The digits showed in the screen is the value of tested sample.

10

Press "ON/OFF" button to turn off the meter
