Product Description:

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.
