II. Performance Features

1. Equipped with a 7-inch touch screen display, the instrument consists of high and low temperature baths, heating device, temperature control device, air supply device, sample container, etc.

2. The instrument uses an air pump to supply gas to the flow meter, gas diffuser, and sample-containing measuring cylinder in a timed and quantitative manner, allowing measurement of the volume of bubbles generated by the sample.

3. The instrument system includes a built-in timing function.
