Product Description

Regular calibration of your pH meter is essential to ensure accurate readings. Essentials pH Buffer 4 and 7 are used to calibrate your pH meter, by providing solutions with a known pH level of 4 & 7. To use, pour a small amount of the solution into a clean vessel, and then immerse your meter's probe into the solution. Tap the probe to remove any bubbles, and allow a few minutes to finalize the reading. You can now manually adjust your pH meter to read either 4.0 or 7.0 (depending on the solution used), or select 4 or 7 from the meter's calibration settings if available.

The packaging was extremely well done.
After having removed all the bubble wrap i noticed that both bottles were wet, so one of them were leaking.
This is a problem because this stuff usually start loosing its pH value from first opening and breaking the seal. I don't know how long one of these were open on not sealed properly....

If you have a ph meter than calibrating the tool is a must. It doesnt take long. But with out doing so you meter will not read right.

well it seems to work fine just submerge the PH tester into an eggcup full of buffer up or down fluid and the ph tester can be adjusted to the required reading or it your ph tester will adjust itself automatically if it has the auto calibration feature on your ph tester....
