Accurately Standardized Solution
I used this product to calibrate a conductivity probe from Atlas Scientific (k=.1). I used a probe from mettler-toledo to compare and the solution was spot on.

Opened bottle.
When I received the bottle, the seal had been completely broken and it had been opened. It is probably ok, but not very reassuring.
