HI2211-02 Benchtop pH/mV Meter with 0.01 Resolution
Details
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 feature. The 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
Ideal for all pH testing water. With its advanced microprocessor it provides highly accurate dependable readings in such applications as hydroponics, purification applications, wastewater regulation, aquaculture, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment, wine, coffee, and agriculture.
