This product is named as ph probe soil tester, while the picture is of the kci storage solution? which product is this?

The probe end of the pH tester needs to be protected when not in use. This stuff is what's use the store the probe in.

How long does a 100ml bottle last, if using the probe once a day?

As long as the cap has solution in it (glass bulb is immersed) when stored, then it should last at least a year. You may need to top it up from time to time, but you shouldn't be rinsing or tipping the contents of the cap out on each use.

This item description is for soil testing however the item pictured is the kcl storage solution. which product is it?

This is KCl storage solution. I have submitted incorrect Product name to the seller.

What exactly is the solution? Thanks
