Model LH-C1 chemical oxygen demand test meter is a new generation COD meter which is promoted by ourself Hangzhou Lohand Biological Co., Ltd in 2017. COD meter solves the problem that when people detect outside without electricity power. COD meter is suitable for test chemical oxygen demand(COD) of surface water,underground water domestic sewage and industrial waste water .
Note: COD meter can also be customized to test ammonia nitrogen ,total phosphorus and residual chlorine and other ions detection curve .Any more information please contact with Lohand .
1.Any liquid or foreign substance entering the inspection chamber may damage the instrument.
2.If the concentration of water samples exceeds the range of the instrument, please dilute the water sample and measure again. The measured value multiplied by the dilution times is the concentration of water sample.
3.There should be no stains, scratches, dust or fingerprints on the surface of the test tube.
Battery requirements: Please use 1.5V AA alkaline batteries.
Rapid digestion spectrophotometry
More than 30 hours
0-50℃ , Rh:0-80%
1.Take 2ml pure water and 2ml tested solution to be added into different COD reagent tubes,screw down the lid,shake the solution in the reagent tube slowly , put the reagent tube into the reactor,react for 20 minutes at 165℃。（Danger: the reagent tube contains concentrated sulfuric acid，please wear gloves when handling,if you accidentally touch the skin, wash immediately with plenty of water.）
2.After reaction ,put the reagent tube on the test tube rack and cooled to below 80℃.(Warming:reactor and reagent tube temperature is high,be careful not to burn during operation.)
3.Shake the liquid in the reagent tube again.
4.Place the reagent tube on the test tube rack and cool down to room temperature.Don't shak e the reagent tube at tihs time .
5.Press “on / off” button to turn on the powert, the screen displays "idLE" that boot is complete ,the reactor is in standby mode.
6.Open the test lid, ensure zero water tube surface clean, put it into a test chamber, cover the lid,press "zero" button, the middle of the screen shows "0" said zero complete.
7.Open the lid, take out the zero water sample ,put the tested water sample into it,cover the lid.
8.Press “read”button,the result will be displayed on screen(unit:mg/L).
9.After the measurement press “ON/OFF” button to turn off the instrument.
