The HI 2209 pH/mV Meter with Manual Temperature Compensation (MTC) provides a simple to use, cost effective method for measuring pH. Designed for durability and simplicity of use, this instrument features a large, easy to read LCD and user friendly dials.
In order to achieve maximum accuracy, the HI 2209 features a manual pH calibration at one or two points. Manual calibration enables the user to select the instrument’s calibration points closer to the desired range of measurement, making them ideal for applications that require custom calibration points. (i.e.- 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.)
The HI 2209 pH/mV Meter can also measure ion concentration (ISE) or ORP (oxidation reduction potential) in the extended mV range with optional electrodes.
