Digital Model 10

The Digital Model 10 is designed as an integrated unit to make oxygen measurements. The standard version includes an electronic magnetic stirrer and the electronics to supply the polarising voltage, signal amplification, and digital display of percentage saturation for a single electrode. 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:

  • operate and adjust the stirring speed;
  • set the polarising voltage between 0–1 V;
  • zero the electronics and electrode output; and
  • calibrate the electrode.

At the rear a socket provides a 0–1 V output suitable for a data logger, chart recorder, or other device.


A comparison chart for our range of controllers is also available.
