Will this give me a reading for the percentage of coolant in the water?

No, there are 2 graduated scales. Propylene or Ethylene. After putting a few drops of the liquid on the glass you hold it to the light and it will tell you the freeze point. If one knew the exact total volume of the loop they could calculate percentage. It is a quality built tool and well worth the money even if you only use it a few times.

Not a percentage reading, but a protection level of the coolant/water mix. Like -10, or -25 below zero.

That depends on water quality input, pre-filtration, and other factors. Manufacturer specs claim a 99% rejection rate when new with a minimum rejection rate of 97%. You can determine rejection rate using a TDS meter. Example: if input water reads 300 TDS and product water reads a TDS of 3, then the membrane is working at 99%. But if TDS is say 12, then your membrane is producing at a rejection rate of only 96% and outside of Filmtec specs.

It works by measuring the pressure in the tank- the higher the pressure, the fuller it is- and the gauge is calibrated accordingly. It's fairly inaccurate due to changes in temperature, but it gives a ballpark estimate on how much fuel is left. I like mine, although a scale would be more accurate.

It reads to .1 gallons so I assume it can measure that low of flow...but I have only run it from 3-8 gpm. Still works after two years.

It does not list the percentage, but the company`s name is listed on the container, I would email them for the answer.

Yes, get the "sight glass" accessory. It's a glass tube on the outside of the chamber that displays the water level inside the chamber.

No, it just measures conductivity and displays the results as total dissolved solids. Pure water does not conduct electricity and will read zero TDS. My tap water reads 130 and after the RO filter it reads 002.

Check the flow rate on your tankless and recirc. Pump that will let you know if it will work.

This is straight, undiluted coolant. You will need to add water, preferably deionized.

20 to 30 percent. remember higher co2 equals higher temps. Dont wait get a cylinder at a tank exchange outlet and start getting really not stress

Your use of the number 0.1% would indicate you're looking for a high level of accuracy. I figure the meter is good for two or three percent plus or minus. I use mine to detect roof leaks. Six to 10 is no leak and 18 or above is a leak. Of course, as stated in the meter description, it'll measure zero to 99%. May be I don't fully understand your question!

Yes, but understand, it only gives you the water temp for the depth it floats at. The lake will have varying temps depending on the different depths where you suspend the thermometer.

I don't know. All it matters to me is that it works. I tried two others before this. I test the water with water quality tester it showed around 24. You can contact the manufacturer for technical questions

One could worry about the exact accuracy of this device, where I feel it is more a relative reading, and tells you the approximate amount of solids remaining in the water. For the most part, after filtering the water, the ZeroWater device reads zero.

Yes it measures fluids. It is accurate and has worked fine for the last 3 months.

check to make sure the impeller is properly installed and that the unit is fully primmed (full of water) would be my guess.

That could be. Take a 20 oz water sample into Leslie's Pool Supply or your local pool supply store and have them check the salinity to make sure. They may even check it for free.
