Description
Bluelab® pH 4.0 Calibration Solution 500mlpH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pH instruments are calibrated to pH7. 0 first (buffer) then to pH4. 0 (slope). Bluelab's EC CF equipment does not need calibrating as they are all factory calibrated. The CF27. 7 (EC2. 77) solution is used as a reference or checking solution to ensure you have adequately cleaned the EC CF probe.

Great to add to the collection
Again, this was an informative book about the character Lisa haha. But like I mentioned in The Bart Book, it only talks about the main character (LIsa) for 50% of the book and the other 50% is about secondary characters. I did enjoy the comic throughout.
This is another fun book to be added to my collection.
