Anyone here familiar with a Newell MRBR hardness tester? A friend of mine acquired one, but there seems to some sort of fluid that needs to go in it. The previous liquid may have left a slight red stain. We debated trying dyed water. Any ideas?

Thanks,
Bruce

Nevermind, we just determined this device isn't going to be accurate for metals lower than 20 rockwell hardness!
