Easy-to-Operate Precision pH Meters
Models pH 210/211/211R
Combining the most frequently asked for parameters, the pH 211 and pH 211R are the popular choice for laboratory bench top instruments around the world. You can measure pH directly, as well as milliVolts for pH, Ion Specific Electrodes (ISE), and Oxidation Reduction Potential (ORP) electrodes. For added versatility pH 211R offers analog output of 0 to 5 V that represents the full pH and mV range. Temperature compensation, either automatic or manual, is your choice and easy to do. The instructions for calibration are presented in a step-by-step display with safeguards to prevent calibration errors.
When your need is solely to measure pH, the easy
choice is pH 210. Calibration is just a few simple steps and is guided by graphics
on the LCD. You can calibrate at 1 or 2 points by choosing any combination of
the 5 buffer values in the meter's powerful memory. These meters offer the best
value in bench top pH measurement today!
