I've just bought a bluelab truncheon coz i was advised that they were the best but now i need a ph tester pen (im currently using the little vial- you add a few drops of reagent to ya water and then compare to the lil colour chart and i hate doing it, it annoys the fuck out of me!!) What is the best ph tester pen??

Euteck

ive just been the the eutech site and was a bit overwhelmed by the range of products!! i would like to know what everyone else uses to test their ph please guys. I want an easy to use, reliably accurate pen, that i dont have to calibrate(if poss?).

I got a essencials 1 and its wank spend the £ and learn to use a good 1. As far as im I know all electronic meters need to be re-callibrated every so often. Im saving for a trunchon 1 too at the min as they seem to be popular. Im looking for one that will do ec and ph if possible but I wont try and scrimp again as important as the plants you grow in hydro

all ph meters need calibrating
the eutech ph tester 2 is a good meter
ya can also replace the probe instead of keep buying new meters
they cost about £70

ya can get cheaper meter like the horticare ones they not a bad meter but not as good as eutech

im gonna go for a horticare ph pen, they're not the best (or so ive heard) but its all i can afford(£35) and i REALLY need it this week. does anyone else use one of these or know of a good one for about the same price??

You could get a constant reading jobby with mains transformer, inbuilt nicads and replaceable bnc gel-filled ph probe on a 10ft lead for about the same money. The replacement probes are about £17, mines over 2 years old and still calibrates ok.

ok, still undecided on the ph pen!! I have been doing a bit of research and found a Senz ph pen. Does anyone use one of these?? What d'ya think??

for the price the horticare will be hard to beat for a low budget meter

i got an aquarium ph tester from ebay for 21 quid the other day, works well. its black and silver with a digital readout

I've got one of the 'pH PAL' hobby pH meter pens (as sold in a chain of grow-shops for about £39.00 (I bought one when they were reduced)).

At first I was hesitant 'cos it looked like the cheap & cheerful option and I was looking for something a little more permanent/durable.

But TBH it's one of the best purchases I've made - the probe appears to have lasted over a year so-far, I've replaced the batteries once and I generally find I have to recallibrate it about once a month if that...

Maybe I scored a good'un, but buying a pen was the most cost-effective option for me...

Cheers
