Alcohol Refractometer

I want to digitally newspaper percentage of alcohol (specific gravity, SG) contained in my washing, (sugar, yeast, water), so I can see the changes in alcohol over time. This is a project I'm working on a hydrometer or refractometer would be if you could interface to connect continuously changes over time. As a part-time project, without "real" funding, I'm looking to do on reading cheap, if possible, (; $ 5,000 sensors are not what I want) I thinking of a large-scale installation consisting of 100 liters of washing with a laser and LDR microphones on the basis to measure changes with refraction. Any help would be greatly appreciated

If you want to stay within your budget you can use the hydrometer to make statements at certain times of the day.

Record time and record also.

CO2 produced by the yeast will not cause bubbles if you have an air pocket in the use and you should, however, the foam made with yeast to collect and make it difficult to read.

Suggest a siphon disinfection and take samples to check with the hydrometer. if the container is sanitized and hydrometer, you should be able to add to the fermenter with a risk for most bacteria.

Good luck.

All I can think of within your budget would be a hygrometer (the floating bulb type manually reading, not an electronic procedure) and read at regular intervals. If you need intervals of less than 8 hours, you may be able to put up a video or digital camera with a timer to take a photo at the interval you want. Just make sure if you do this so that you are using the hygrometer can be read from any angle, not just forward.

Remember that the hygrometers are temperature sensitive so you must either register the temperature reading of the hygrometer implement your project in a constant temperature. If high precision is required, you must also take into account the atmospheric pressure!
