The pH 209 benchtop pH meter is designed for durability and simplicity of use. This instrument features a large, easy to read LCD and user friendly dials.

 

The pH calibration is manual at one or two points using dials on the front panel making them ideal for applications that require custom calibration points.

 

In many applications, a standard calibration curve such as pH 7 or pH 4 is too far from the value of the sample to achieve the highest accuracy. Manual calibration enables the user to select the instrument’s calibration points closer to the desired range of measurement to achieve maximum accuracy.

 

The pH 209 can also measure ion concentration (ISE) or ORP (oxidation reduction potential) in the extended mV range with optional electrodes.

 

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