Dual Digital Model 20
The Dual Digital Model 20 is designed as an integrated unit to make oxygen measurements. The standard version includes two electronic magnetic stirrers and the electronics to supply the polarising voltage, signal amplification, and digital display of percentage saturation for two electrodes. The only additional requirement is a supply of constant temperature water to the incubation chamber to ensure accurate readings
Located on the front panel are controls to:
-
Switch the display between the two electrode outputs;
-
Operate and adjust the stirring speed;
-
Set the polarising voltage between 0-1V;
-
Zero the electronics and electrode output
-
Calibrate the electrode
At the rear a socket provides a 0-1V output suitable for a data logger, chart recorder, or other device
