Clarkson HI208-02
Educational pH Meter with Built-In Magnetic Stirrer 230V
Hanna Instruments HI 208-02
Description:
Compact and lightweight
Built-in beaker and beaker-top electrode holder
pH and temperature in one probe
Built-in magnetic stirrer
Dual-level LCD
Automatic calibration
Operated by battery or 12 VDC
°C and °F temperature scales
With features such as a built-in beaker holder, beaker-top electrode holder and rugged,
2-in-1 pH and temperature sensor, the HI 208 is designed to meet busy classroom environments.
This instrument also features an extended pH range, dual-level LCD with icons for stability
and buffer recognition, built-in magnetic stirrer, automatic pH calibration, and temperature
display in either Celsius or Fahrenheit. In addition, all readings are automatically compensated
for temperature variations.
In the classroom, this compact unit reduces clutter and utilizes a minimal amount of space on
the desktop. Switch to battery power and the instrument can be taken outside the classroom for
field studies. When lab time is over, the instrument is easily cleaned and can be placed out of
the way—right away.
(*) The temperature range is limited to 80 °C (176 °F) if using the HI 1291D probe.
