I.Applicable standard

SH/T 0722  ASTM D6082

II.Performance characteristics

This instrument is suitable for measuring the foam characteristics of lubricating oil (especially transmission fluid and engine oil) at 150 °C. The instrument adopts the advanced PID self-tuning temperature control system, the control performance is stable and reliable, the user only needs to set the temperature control point temperature through the instrument, the instrument automatically realizes the fixed point temperature control, digital display, accurate temperature control, and the accuracy can reach ±0.2℃. Air bath heating, safe and environmentally friendly. High temperature resistant quartz glass measuring cylinder, safe and reliable. Powerful circulating fan ensures the balance of temperature control. A lighting lamp with adjustable brightness is installed in the bath, which is convenient for experimental observation. Each group of tests is independently temperature controlled to ensure the accuracy of the test temperature. Equipped with stainless steel diffuser head imported from the United States. No oil-feeding air pump to ensure airflow supply. With timing alarm device.
