PRECISION PETROLEUM TESTING INSTRUMENTS

Oxidation Characteristics of Inhibited Mineral Oils – ASTM D943, D2274, D2893, D4310, D7462 | EN 12205

 


The 501, HT-342, and 30 Series all meet the requirements of ASTM D943, D2274, D2893*, D4310, D6158, AOCS12-57* , ISO 4263, ISO 12205, IP 388, DIN 51 587, NF M07-047, NF T60-150 test methods (* modified version for these methods is available).

To suit your laboratory needs, our oxidation instruments come in three types of baths: heated liquid baths, heated aluminum block baths, and individually heated tube baths. Each type of bath has its own advantages. Heated liquid baths are low cost and considered the traditional and most universally accepted bath type. Heated aluminum block baths eliminate the need for expensive and hazardous bath mediums which benefits laboratory safety, health, environmental, and maintenance issues. Lastly, individually heated tube baths have all the benefits of aluminum block baths plus tighter temperature stability and the ability to operate each test position at different temperatures.

Each test position has one float-in-tube flowmeter positioned in front. The oxygen flow rate is maintained at 3 ± 0.1 L/hr with a micro precision valve. An oxygen pressure regulator is optionally available.

Temperature control is provided by a digital display PID controller providing stability of ± 0.2º C or better. In the event of primary controller failure the bath is protected by a secondary high limit controller. Useful temperature range is from 40° to 120°C.

The 30 or 60 positions are arranged in two back to back rows (15 or 30 positions each) or in straight line.

Floor models come standard with a on/off water valve for the condensers. Upon request other arrangements can be made for water flow for both bench and floor models.
