Clarkson P2960-PH211
pH/mV Bench Meter for Quality Control Applications
Hanna Instruments pH 211
Description:
The pH 211 is an advanced microprocessor based pH/mV bench meter that is easy to operate,
precise and inexpensive making it perfect for Quality Control laboratory applications, as well as a
wide range of other measurement applications.
The pH 211 performs pH, mV and temperature measurements, and the large display shows pH (or
mV) and temperature values simultaneously. It come equipped with 5 memorized buffers for pH
calibration (pH 4.01, 6.86, 7.01, 9.18 and 10.01), and the automatic recognition system eliminates
calibration error. The user is guided through the calibration process with simple instructions on the
display.
Temperature compensation is automatic through the probe supplied with the instrument; if necessary
the user can also set temperature compensation manually.
