Model pH 300
pH
300 is the basic model of the 300 series and it is manufactured according to
CSA, UL and CE standards. It features simplicity of use together with state-of-the-art
engineering to measure pH, mV, ORP and temperature. Graphic symbols and messages
appear on the LCD to guide the user step-by-step through the calibration procedure,
which can be performed at 1 or 2 points from among 3 memorized buffers (pH 4.01,
7.01 and 10.01). A "CFM" message blinks on the LCD until stability
is reached, and only then calibration can be performed. This guarantees that
only optimal calibrations are carried out.
The calibration date (month, day and year) and
data (offset and slope values) are stored into nonvolatile memory, and can be
easily recalled by the operator. Erroneous and inaccurate measurements due to
non-calibrated system can be avoided with the pH 300 last calibration data recall
function, which warns the user in the case of an overdue calibration. With these
features pH 300 meets the requirements of Good Laboratory Practice (GLP). Your
work can be transferred into a computer via the opto-isolated RS 232 communication
port and with the aid of HI 92000, the user friendly Windows® compatible
software.
