Ph spot on
it is very good giving a better read out than using test strips ,my tanks have modern substrate which tends to make the ph of the water very acid below 6.5 and the test strips were not very accurate , using this I can adjust the ph better I use bicarbonate of soda keeping the water at about 7.5 or just under ,also you can check the temp and tds

No cord to hang from side of tank/Bucket
Excellent meter but its shame it doesn't include a nice red hanging cord. That was quite disappointing.

So far so good. These have never lasted a couple of growing sessions and needed replacing the Ph function always goes so I hope this one is better.
