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

it helps in keeping the the test probe from drying out .i highly recommend it been using the same blue lab ph pen for over a year and id like to think its from storing it properly. blue lab is the way to go

Perfect

This stuff is good. The One Pen from Blue Labs cost too much not to buy the best products to keep it working properly. This storage solution works. I will be buying more to keep my meter safe.
