Can this product be used in place of the "1382 milligram per liter (ppm)" calibration packages ?

This is for calibrating EC not ppm. There is a different solution for ppm.

How long is it useable after opening?

I believe as long as the cap is kept on it after use it should be good for many months. We have some at work that is a couple of years old and it still does the job. Just don’t want any evaporation as that would increase the EC of the solution.

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.
