HI8424NEW - Waterproof pH Meter with Automatic Calibration
and Temperature Compensation
|
The HI8424NEW portable pH meter, one of the most popular pH meters on the
market. By utilizing an advanced, custom microprocessor, HI8424NEW is able
to perform pH, ORP and temperature measurements with high accuracy and fast
response. The mV measurements automatically switch from 0.1 to 1 mV
resolution when the reading reaches ±699.9mV. Temperature effects are
automatically or manually compensated for, from 0 to 100°C (32 to 212°F).
The meter has 3 memorized butter values (pH 4.01, 7.01, 10.01), and automatic
buffer recognition to avoid errors during calibration. When turned on, the
mete shows the percentage of the remaining battery life.
Thanks to the HOLD function, the reading can be frozen on the display to
be logged manually. Moreover, the temperature can be displayed in °C
or °F, the user can enable or disable the Auto-off feature, the acustic
signal, the back-lit display. In addition, HI8424NEW indicates on the
display the buffer values used for the last calibration. Price includes
meter, HI1230B pH electrode, HI7662 temperature probe, calibration and cleaning
solutions, battery, protective case and instructions. |
