Hanna HI208 Educational pH & Temperature Meter with Magnetic Stirrer

The Hanna HI208 educational pH meter is a compact pH and temperature bench meter with a built-in magnetic stirrer, designed for practical pH measurement in school and teaching laboratories.

The HI208 combines pH measurement, temperature measurement and sample stirring in one instrument, helping reduce equipment and clutter on the laboratory bench. The supplied HI1291D probe measures pH and temperature simultaneously, allowing automatic temperature compensation of pH readings. The meter can operate from the supplied 12 VDC adapter or a 9 V battery for portable use.
