Petroleum Oxidation Stability Tester

*** YOU MUST ORDER 1 TO 4 x K11000 OXIDATION BOMBS AND 1 TO 4 PRESSURE GAUGES (1 per bomb) OR A 4-UNIT ELECTRONIC PRESSURE MEASUREMENT FOR LUBRICATING GREASE OXIDATION TESTS. YOU WILL ALSO NEED TO ORDER 5 DISHES PER BATH AND THERMOMETER(S)***]

The sample is oxidized in a bomb initially charged with oxygen at 110psi (758kPa) and maintained at elevated temperature for a specified aging period. The pressure drop inside the bomb is measured by means of a gauge or transducer.

SPECIFICATIONS:
Capacity: 4 Oxidation Bombs
Temperature: Range: Ambient to 221°F (105°C)
------------ Control Stability: ±0.09°F (±0.05°C)
Bath Medium: 7.2 gal (27.2 L) water or white technical oil

OXIDATION BOMB:
Stainless steel bomb consists of body, lid with stem and needle valve, and dish holder per ASTM specifications. Bomb interior surfaces and inside of stem have a high polish to facilitate cleaning. Safely withstands a working pressure of 180psi (1241kPa) at 99°C (210°F). Includes PTFE gasket seals (3) and cap screws with wrench. PTFE fluorocarbon seals are available (see Accessories).

PRESSURE MEASUREMENT & RECORDING EQUIPMENT:
Select mechanical pressure gauges or, for greater convenience and accuracy in test reporting, the Oxidata Pressure Management System designed expressly for ASTM oxidation tests. Pressure gauge measures pressure inside Oxidation Bomb with accuracy of better than 0.5psi (3.45kPa) in accordance with ASTM specifications. Range: 0-160psi (0-1100kPa), graduated in 1psi intervals. Cleaned for oxygen service.

OXIDATION BATH:
Constant temperature oil bath holds bombs at the proper depth for determining oxidation stability of lubricating greases Fully digital touch screen controller provides quick temperature stabilization without overshoot, and the bath is protected by a redundant overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Display provides actual setpoint temperature values in °C/°F format. Contact your Koehler representative for information. Heavily insulated welded stainless steel bath interior has a bomb support rack and overflow standpipe/drain to maintain proper working depth. Steel exterior has a corrosion resistant polyurethane enamel finish.
