That's not really true, is it?
The Milwaukee unit certainly has the capability to allow a 2 point calibration even those it's rarely used. Some people do use it though.
Your comment is like saying your car doesn't have high beam lights because you don't use them when in fact it certainly has that capability.

Naja002, what do you think of this comment?
Would you say that the Pinpoint pH controller is only capable of a single point calibration because that is what someone is doing even though the controller certainly has the capability to do a two point calibration?
If it was decided to use either of these controllers for a purpose that required that a 2 point calibration must be done for that purpose, would you still say that they are single point calibration controllers?
Last August on Rex's form you posted a thread called: "
Looking for Feedback---C02 Equipment Page...." You were asking for people to review your web page and give feedback. I told you this:

Facts are facts. If it's there, it's there.
I really doesn't matter to me what you think about these controllers, but you shouldn't be giving bad information.
What would a person think that just bought one and read the instructions showing how to do a 2 point calibration and then they see your comments saying that it doesn't have that capability? Would they be confused? What would they think about your comments?
Are you using either of these pH controllers, anyway?
