It does the job by JOSEPH BECKER

Comments: If you have a pH probe and need to calibrate it, this is what you'll need to get started, in addition to the pH 10 fluid if you're setting your probe for saltwater use. It does the job well, and there is ample fluid in the packet to submerge your probe. An added plus is a handy table on the back showing the pH value across a temperature range. Unfortunately solutions like these cannot be reused. For 99 cents, you can't beat the price, but it does hurt to pay full shipping charges on something so inexpensive. Best to buy a few at a time (a good idea for periodic recalibration) or just wait until you're ordering something else and tack a few onto the order. Yes, I would recommend this product to my friends.
