We have collected many testers. Apera is a brand we trust, an opinion based on years of experience using testers like this for dairy as well as PH and EC, EC20 etc. It's not one that comes with a portable case for portable devices, and this type of tester doesn't use pre-mixed calibration solutions, but it does come with batteries and its collapsible stand allows it to be used as a benchtop meter. Apera Instruments testers have large screens to make readings easier to read (these are the only testers I can use without reading glasses). Testers from Apera Instruments impress with their simplicity and precision. Those that include pre-mixed calibration solutions have been shown to save time. For me and my sometimes clumsy fingers and knowing that testers swim! I recommend the Apera testers to both beginners and experts for their accuracy, ease of use and quick readability.
