    อุปกรณ์วัด pH (pH and temperature indicator with backlit display)

    HI 991401
    pH and temperature indicator with backlit display

    This indicator model Hanna is characterized by the large dual level display backlight, which allows you to keep under control the pH and temperature of the solutions, even in low light environments. Moreover, thanks to the internal microprocessor, HI 991401 is both very accurate and simple to use, because it is equipped with automatic calibration recognition of memorized buffers and automatic temperature compensation.
    All the features of HI 991401 are designed for the difficult operating conditions typical agriculture and hydroponics. Thanks to the 12 Vdc adapter (included), batteries are no longer a problem.
    The pH electrode supplied is designed for long life in the presence of fertilizers with high concentrations of corrosive substances such as phosphates and nitrates and ensure accuracy of reading was added Matching Pin-in temperature sensor. When it is time to replace the pH electrode, the DIN connector makes this easy and fast.
