ORION RESEARCH microprocessor pH/millivolt meter 811
Model 811 ORION's pH and ISE meters are easy to learn and operate. The· Model 811 has just two controls. At the push of a button the 811 automatically locks onto the temperature-corrected values of your pH buffer. With the mode switch you select readings in pH, solution temperature, electrode potential, electrode slope and time of day. The 811 tells you when to take your pH reading and warns you about problems before erroneous data is recorded. You can verify that the 811 is operating properly by using the built-in test mode. Just push the test button located in the back. For equal ease in measuring ion concentration ORION offers the Model 901 Microprocessor lonalyzer,® also with simple, pushbutton operation. The 901 reads directly in the concentration unit of your choice for fast results. For more information on pH and ISE products call ORION at 800-225-1480; in Massachusetts, call 617-864-5400.
