Ph Meter

[ulster exile]

Can anybody recommend a decent but not too expensive (if possible) PH meter please?

loads of 'cheapies' on ebay at the mo £15 inc postage. don't know how accurate, but they do the job without having to use tubes and drops etc.

Hanna make excellent very good qualty pH meters. I use the pHep5 and am very happy with it. Retails at around £60. http/www.hannainst.com/products/testers/...0-%20HI%2098128

Well done. Does it come with the pH buffers for calibration and the storage solution for the cell? I use the pH4 and 7 buffers for calibration. They can be brought pretty cheap off the internet. The storage solution is basically 4 molar potassium chloride solution which is what I use as the commercial ones seem a tad expensive to me.

No, it doesn't have any of that, but I can cope with buying those separately, so I'll start looking for those.

Thanks very much for all the help/advice - it's very much appreciated (especially when I look at the pics of your tank as I can see that you're talking from experience).

No probs. I tend to calibrate mine about once a month as it doesn't seem to drift very much. What you must do though is to keep the cell moist or it will be ruined if left to dry out for too long. For the short term you can use pH4 buffer solution but get some storage solution or KCl asap.
