I too use Pinpoint, and it works perfectly!

Thanks for all the replies. According to the spec., the Milwaukee comes with an alarm for monitoring. Does Pinpont has it too?

No, it doesn't have an alarm. When does the alarm on the Milwaukee sound? It seems to me that there wouldn't really be a reason to have one, if you check your pH daily. I can't imagine a huge swing (that occurs rapid enough where you wouldn't notice a trend) unless you add a supplement that causes it.

I am at the point that i need a new ph meter is it beter to go to a ph controler or do you still use a ph in-line monitor as well. Please pass on you thoughts i will probably buy one this week ...Jeff

Just find out that I need to buy a PH controller not a monitor for the cal. reactor. The Pinpoint PH controller is about $190 in MarineDepot.
The Milwaukee controller is about $80. However the Accuracy is about ± 0.1 pH VS the Pinpoint is ± (0.01 pH or 1 digit).
Apprentice, if you planning to get a new one just for a monitor. I think I would get the Pinpoint since a lot of people use them. For controlling the Ca. Reactor, I think I will get the Milwaukee for the price.

you may not need a controller for your calc reactor. some of that depends on the size of your tank and the type of reactor and whether that model tends to swing the ph more than other models. i wouldnt assume you need a controller. if money is tight then i would do some more homework before spending the dough. if money isnt an issue then go for it. as for types, ive heard really good things about the milwaukees and they are cheaper. i own pinpoint but would look seriously at milwaukees if i could do it again.

On the Milwaukee monitor it does have an alarm but i wouldnt really call it an alarm... It does work great.. I havent really had any troubles with it at all.. The alarm itself just flashes a little red light if it goes over a certain ph... It only works for a high pH Alarm... The monitor also only reads in increments of .1 where as the pinpoint reads in .01 increments... To be honest the milwaukee meter works better than any test kit but If I were to go back in the past I would have went with a pinpoint..

Well from the comments and feedback it looks like Pinpoint is the beter controler/monitor and i am leaning toward buying the AM1311 model This model not only is a monitor but if i do need to control Ph in the future i will have the ability to do so. I haven't had much if any changes of ph in my tank but i want to get a more automated / stable runnning tank for reliability.:D
Thanks to all that posted feed back and helped me out..Jeff
