Ok so I'm picking up a few bits and pieces from China for the brewery ;D
Anyone got a reccomendation for a cheap pH meter?
This (http://dx.com/s/ph+tester+meter?topsearch=2) is what dealextreme throws up, I'm considering this one (http://dx.com/p/1-2-lcd-ph-tester-meter-green-blue-4-x-ag13-127983)
Whadda you think
I got one for a fiver on ebay. I'll see if I can find the link.
If memory serve me,I think there has being alot of comments on JBK about not buying cheap ones. :-/
Yeah, I remember reading some recommending not getting cheap ones. But to be honest I don't use mine much, and it's served me well so far.

Yeah I've read quite a few of those, what can I say I'm cheap ;D
If you do buy a cheap one then think about googling up some calibration solutions ( about €10 or so ).
Calibratable meters usually have 2 cal. points:
pH 4.0 and ph 10.0
Usually 3 solutions the two above plus pH 7.0
Its worth calibrating every couple of week or so.
Also: The working end of the meter needs to be kept wet in a storage solution ( usually quite acidic )
Also; You need a source of de-ionised water to rinse the sensor before/after use.
If theres no mention about calibration in the chinglish destructions then you may be better of with narrow range pH test strips!
