this tester does the job but all meusurements are not so precise only the temp is spot on. The Ph test will only work if you clean the tip and shaft with steel wool, to get the oxidisation off, only then you get a reading within 0,5* of the real value. I tested this tester against my Ph meter for my aquarium whitch is acurate to 0,1*.
