Ok then, thats my calling in life. I will invent a cheap, reliable electronic salinity meter!!
Actually, I have been wanting to start a project to make a computer controller and logger with wireless internet capabilities. It would have hook ups for various probes (pH, temp, salinity, ORP etc...) it would have a proportional temp controller and pH controller built in and constantly log data which you could wirelessly download to your computer for analysis and storage. It would even be able to send out email alerts such as "Temp is getting too high" etc.... You could even log into it remotley from work to view data in real time and reconfigure it. I would also include a web cam with broadcast capability. You could log into the controller from work, see all your tanks parameters, reset and control from there, view past data and see real time images of your tank.
I know there are similar products on the market but I bet I could do it cheaper.
I just have to find the time!!
