TRANQUILITY IS A SELF MANAGED SHARE BOAT

At 58 feet length, TQ (as we call her) is a steel hull narrow boat built by Colecraft and fitted out by Elton Moss Boatbuilders. Currently based at Droitwich Spa Marina in Worcestershire we're able to cruise some of the most popular waterways in Britain. The Worcester & Birmingham, The River Severn, The Droitwich Canal, The Gloucester & Sharpness Canal and more.

Our friendly Syndicate decided to go down the Self Management route on 1st March 2012 and so far it has been very successful. Please visit the other pages in this blog to see the new Web Site and if shares are available for sale. (There'll not be many).
I CAN CONFIRM THERE ARE SHARES CURRENTLY FOR SALE!

Does anyone know what this is?

It's a refractometer.
It's used for checking the amount of a liquid in another liquid, alcohol in wine or soluble oil in water for example. In this case it's for measuring antifreeze in water.

I checked the coolant in the engine today and we're good for temperatures down to minus 35°C.

The clear plastic window is hinged and lifts to allow a sample to be placed on the blue prism. The clear plastic window is closed onto the sample expelling as much air as possible. Holding up to the light a reading is taken through the scope. A graticule scale of various similar liquid types shows the mixture richness at the blue/white interface.

You can check the SG of your batteries as well

Hi Brian and Diana,
Yes, this one will check battery SG and Adblue for larger diesel engines. I have another one at home for checking the percentage of oil in water - coolant for machining metals.
Happy New Year to you.
