Give it a go with the pointy end of a pencil and then you can work from there.
A couple of go's and you'll know how big a drop will move it how far.
In fact a pencil with the lead nipped out of the end would be perfect.

Once you get the hang of it it's ok.
I can bang on a 10L bucket in less than 5 mins.
They're starting to drink so I'm on every 3 days, that'll end being every 2 in full swing..

Yeah, it tells you the Rough PH of your medium rather than the water you are putting in.

it'll just show you how much the ph is changing going through your substrate. i'd make sure you run off tray is clean before checking it tho, ive noticed a build up of salt in mine from evaporation.
i got some of those pipets off ebay. i tried making my nutes up in a 2L bottle at the start but i had to start using the 15L bucket and then its only a few drops to get it to the right ph. when im giving them near full strength nutes i dont need to ph, i find its only at the start when im using rhitzonic

For example when I opened a brand new bag of Plagron soil the water was going in at 6.5 and coming out at 5.9.
Hence I had to flush it a little for the first few waters after transplant.

Lol see you lads have got the cheap chink ph pens I had 1 to start with there utter bollocks lol....you do need both powders to caliberate it propa dura read the instructions I no there shite an don't make much sense lol but it kinda tells you how to do it....also your ment to use ro water or your mixers ph will be off so ur pen will be off, I ordered 500ml of eBay mixed um up then kept um in little pop bottles so I could 're-use....also them cheap fuckers your best calibrating about once a fortnight I used to an it was always .2 out. Also to get a propa reading it takes ages with them you have to keep retestin till it finally stabilizers
Best thing I ever did was gettin a decent ph pen!

Also if a drop is to much when ph'in best thing to do is get a little eye dropa an full with water then put a drop or 2 in that then use that to drip in the weaker mix....and always write ya start ph down an finish, how much ya mixin an how many drops so saves you guessing an fuckin it up an saves time you can skim back an look how many drops it took you before then after abit you can just remember roughly how much ya need...

You in canna dura?.....owt from 5.5 to 6.2 is good I only shoot for 5.8 incase me pen is out by a point or 2 either way.........Id love to have tap at 7 mate you will find the more base notes you add the more in the safish zone you will be an not even need to bother mine is near enough 8 I always have to.

Getting more complicated by the post here 
so next question, is the water in my dehumidifier reverse osmosis water?

Lol it's a piece of piss mate in coco, dwc is abit trickier I've ready at diff stages you do diff phs cos at different stages the ph will drift somethin to do with the plant using different stuff more at diff times an shit lol enjoy mate.......yeh that water is sound mate.
You will be mate I've always said 7 is perfect for canna all the lads that don't ph an do good will all be around that......you got the rhiz? That raises it loads so you might have to early veg when that's goin in at full but after that you'l be laughing mate.

No mate, it's just the condensed moisture from the air in the room.
Why do you ask that?

"Why Does pH Change?
The ratio in uptake of anions (negatively charged nutrients) and cations (positively charged nutrients) by plants may cause substantial shifts in pH. In general, an excess of cation over anion leads to a decrease in pH, whereas an excess of anion over cation uptake leads to an increase in pH. As nitrogen (an element required in large quantities for healthy plant growth) may be supplied either as a cation (ammonium - NH4+) or an anion (nitrate - NO3-), the ratio of these two forms of nitrogen in the nutrient solution can have large effects on both the rate and direction of pH changes with time. This shift in pH can be surprisingly fast.
Daylight photosynthesis produces hydrogen ions which can cause the nutrient acidity to increase (lowering the pH). At dusk photosynthesis stops and the plants increase their rate of respiration and this coupled with the respiration of micro organisms and the decomposition of organic matter uses up the hydrogen ions so the acidity of the solution tends to decrease (pH rises).
In low light (overcast days or indoor growing environments) plants take up more potassium and phosphorous from the nutrient solution so the acidity increases (pH drops). In strong intense light (clear sunny days) plants take up more nitrogen from the nutrient solution so the acidity decreases (pH rises)."
