The total nitrogen meter is a new product which is promoted by ourselves Hangzhou Lohand Biological Technology Co., Ltd in 2018. It solves the problem when people detect outside without electrical power.
Attention :
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 the 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.
Note:
1. The activator is irritating, wash immediately with plenty of water if touched with the skin.
2. Any solution or foreign matter inside the detection chamber, may damage the meter.
3. If the concentration of the water sample is higher than the test range, please choose a high test range for testing, or if tested after diluting with distilled water, the test result should multiply by the dilution ratio.
4. The surface of the test tube should avoid water logging, scratch, dust, fingerprint, and so on.
5. Take action to the sequence and numbers of activator adding.
6. The reagent bag is easy to tear.
7. The sucker of the pipette can not be used crossly
8. The meter should be placed on the table, it can not be tilted or shaken violently when testing in another place.
