Solaxx Safe Dip pH Buffer Recalibration Tablets Safedip Water Tester - 10-Pack

Put in water, dissolve, calibrate.

Just what I wanted

I like that it is readable and reliable. A little intuition goes a long way after using the device and tablets after a while. It is like riding a bicycle.

You need the powder and a glass of deionized water (like distilled water) so solution is neutral and at 7.0ph, then device will calibrate properly. I had been using it for months with accurate results in a salt chlorinated pool. I have other devices, believe me, but this is king.

The batteries in this device seems to last less than two weeks.

Zero instructions on how to use. Oh wait, it says dissolve 2 tablets into 2Tbsp of water. First this means you only get 5 uses out of this expensive buffer. There are no other directions.... If you go to the SafeDip instructions it says put the buffer packet (no tablet) into 8oz of water and then instructions from there. So $30 in on a $170 device to calibrate it and no idea how to use these tablets. By the way, a large bottle, equivalent to about 100 calibrations, called 7.0PH for fish tanks is $6 at a pet store. Just shows you what a scam this is, and SafeDip also. SafeDip is a crappy expensive product and this product is just piggy backing the garbage. But, it looks cool, don't get sucked in!

good product

Solo deja el aparato inservible no lo usen ya que es imposible volver atras porque los sobres para calibrar (que si funcionan)que trae el aparato cuando es nuevo no se consiguen
