Jual HI 2211 Bench Top pH Meter

The HI2211 is a basic affordable pH/mV benchtop meter. Operation is simplified to calibration, mode selection (pH or mV), and a last stored reading HI2211 has a selection to choose between pH and mV modes. The mV mode is used with an optional ORP electrode that is used to check the oxidation or reduction potentials of a solution. Hanna offers a variety of ORP electrodes from glass to PEI plastic body styles. The mV mode of the HI2211 is also useful in checking the offset and slope of the pH electrode. Understanding the offset and slope characteristic is helpful in knowing if the probe is functioning correctly.
The HI2211 has a separate inputs for a BNC pH electrode and thermistor temperature probe. The BNC connector is a universal connector that is commonly available and allows the user to select from a wide variety of pH and ORP electrodes for their particular application. The separate temperature probe provides for a high 0.5C accuracy measurement for precise temperature compensation.
