Specification :

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.
