Review: 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
Review: Good product - Works straight out the box easy to maintain
