Specification :

pH 209 is a rugged laboratory pH meter, specifically designed for students.

The keypad has soft membrane keys for changing modes, and easy to use knobs for calibrating slope and offset.

The pH offset and slope are designed as manually adjustable in order to display the calibration concept and electrode characteristics to the students.

Measurements in pH can be performed with manual temperature compensation, and the selected temperature is displayed to ensure better accuracy.

The meter also measures ORP ( Oxidation Reduction Potential) .

Practicality, simplicity and comprehensive operating procedures make this meter one of the most popular student pH meters available today.

For added versatility, pH 209R offers analog output ( 0 to 5 V) , that represents the full pH and mV range.
