Oxidation Stability of Greases Test Apparatus
Consists of Oxidation Bombs, Sample Dishes, Pressure Measuring and Recording
Equipment and Oxidation Bath.
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 and 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
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
Oxidata™ Pressure Measurement System – A complete electronic
measurement system based on powerful Oxidata™ software for Windows®
environments. Electronically measures and reports pressure versus time and
accuracy of better than 0.5 psi (3.45kPa) in the range of 0-200psi
(0-1378kPa) for four channels in graphical tabular format. Included RTD
attachment permits measurement and reporting of bath temperature. Includes
transducers, data acquisition card, multiplexer, Oxidata™ software, RTD probe
assembly and connecting cables and hardware. Refer to K70502
for complete specifications on Oxidata™ software.
Oxidation Bath – Constant temperature oil bath holds bombs at the
proper depth for determining oxidation stability of lubricating greases.
Microprocessor PID control provides quick temperature stabilization without
overshoot and the unit is protected by an overtemperature control circuit
that interrupts power should bath temperature exceed a programmed cut-off
point. Dual LED displays provide actual and setpoint temperature values in
°C/°F format. Communications software (RS232, etc.), ramp-to-set and other
enhanced features are available as extra cost options. 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.
Also available–Special baths to accommodate two test methods:
• ASTM D942 and D525 (Oxidation Stability of Gasoline–Induction Method, refer
to K10400 and K10401)
• ASTM D942 and D972 (Evaporation Loss of Lubricating Greases and Oils, refer
• Higher temperature models are available.
Please contact Koehler’s Customer Service for additional information.
