Atlas Scientific Dissolved Oxygen Sensor Kit

My experience so far after just a couple of weeks of testing this is that its output tends to drift downwards over time, as if the electrolyte solution that you put into it were leaking out. The membrane in the cap of the probe is a bit flimsy, so perhaps that is what is happening in my case. The datasheet says that the electrolyte should last for 2 years before it is depleted, but I had nearly zero DO2 output after two weeks and had to add more. I am going to try keeping the probe in a small container of water when not in use, so that the membrane does not dry out. Hopefully that will prevent leakage of the electrolyte.

Once you have everything set-up, the DO probe performs very well with little maintenance. Would love to see the price come down on this, but most of the cost is in the probe itself and Atlas Sci. products are on the higher priced side. Works best using I2C.

Thank you for ship my order quickly, I will make order next time

I am very pleased with RobotShop. The products work very well and delivered quickly

The product arrived with good condition. But next time I hope robotshop separate this item from other goods with special box, I am worried the liquid part leak and contaminate other goods, This item prefect for advance hydroponic automations, looks expensive but comparable with its functions
