Hanna Instruments pH 300, pH301 and pH 302
are professional bench-top pH meters for pH,
ORP (Oxidation Reduction Potential), ISE and
temperature measurements. Their built-in mi-
croprocessor ensures accurate and user-
friendly operation.
pH measurements are automatically compen-
sated for the temperature effect (ATC).
These meters come equipped with a large,
easy-to-read LCD which shows the pH or
mV or ION (for pH 301  only) with tempera-
ture simultaneously. The display has graphic
symbols to make the calibration procedure
easy to follow. Calibration is not allowed until
the electrode has stabilized to ensure accu-
rate measurements.
Through the RS 232 serial port you can
transfer sample measurements to a PC.
