I. Summary

The instrument is designed and manufactured in accordance with SH/T0308 and ASTM d3427. It is applicable to study the air release property of petroleum products such as turbine oil and hydraulic oil.

After heating the sample to a certain temperature, inject compressed air into the sample to introduce small bubbles in the sample. After stopping the air flow, record the time when the volume of entrained air in the sample decreases to 0.2% to evaluate the air release property of the sample.
