Air Release Value Apparatus

Part Number 15840-0

The Seta Air Release Value Apparatus is designed to determine the air release properties of hydrocarbon based oils in accordance with ASTM, IP and other methods.

The apparatus is a benchtop instrument with integrated density balance, heater, temperature control system, pressure regulation and microprocessor based control system.

A unique slider arrangement allows easy positioning of the sinker and movement throughout the test cycle.

Air Release Value - why is it tested?


Operator Safety:
- No need to handle hot sample vessel
- Exhaust filter system extracts noxious flames
- Heating prevented when there is no air flow
- Safety cut-out prevents overheating
- Protective safety shield around vessel

Ease of use:
- Removes traditional operator problems
- Sinker is permanently fixed to balance and sample raised up over it
- A mechanical vessel platform allows sample to be quickly and precisely moved between test modes

Precision and Accuracy:
- Automatic timing and regulated aeration ensures stable density and test repeatability

Enhanced Test Throughput:
- Temperature control minimises sample heat loss and speeds up start of test
- Automated test sequence optimises time take for each stage of test
- Quick connectors on glass vessels minimise assembly and cleaning time
- Allows preheated samples to be tested in rapid succession
