Salt drop test

[waterbear]

Also, I have double checked the aquachek salt test strips several times against a meter and they are pretty much in the ballpark and fairly easy to read (but the test does take a while to complete...not exactly dip and read!) they use the same chromate/siver nitrate chemistry as the drop kit but the drop kit does give better resolution (accuracy) at higher salt levels (above about 2500ppm or so)
