Introduction
The apparatus is suitable to test ability of oils to separate entrained air,such as turbine oil, hydraulic oil etc.
Heat the oil sample to temperature 25,50 or 75℃,blow compressed air through the test oil,make make it stirred strongly.Air becomes small bubbles in the air,that is entrained air.After the air is stopped,the time required for the air entrained in the oil to reduce in volume to 0.2% is recorded as the air release time.
Characteristics
1. Micro-computer processing and PID controlling,digitally display set and real temperature,accuracy 1℃,Pt100 RTD temperature probe.
2. Working temperature range:ambient~80℃,accuracy can adjust to ±0.1℃
3. High precise air regulating valve,control pressure to 19.6 Kpa accurately.
4. Stainless steel constant water bath is corrosion resistant
5. LED display working pressure
6. Each tap can be connected easily
7. Timer can display time,manual timing is not needed
8. The case is treated with Electrostatic spraying and high temperature baking,beautiful and elegant.
9. Independent air filtering and Voltage stabilizer,can reduce water and oil in air.
