II. Performance Features

1. The instrument consists of high and low temperature baths, heating device, temperature control device, air supply device, sample container, etc.

2. The high and low temperature baths are controlled by a digital temperature controller for accurate temperature regulation and intuitive display. Easy to operate (for detailed operating steps, refer to the temperature controller manual). When the bath temperature is below the set value, the temperature controller activates the heating device via a solid-state relay; when the bath temperature exceeds the set value, the temperature controller deactivates the heating device via the solid-state relay, and the stirring device ensures uniform and constant bath temperature.

3. The instrument uses an air pump to supply a timed and定量 amount of gas to the flow meter, gas diffusion head, and sample-containing cylinder, allowing measurement of the volume of bubbles generated by the sample.

5. The whole machine features compact structure, elegant appearance, and convenient operation.
