*** 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.
Features and Benefits
- Conforms to ASTM D942 and related specifications
- Four sample testing capability
- Oxidata Pressure Measurement System is available with this system
K10901 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 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.
Oxidata Pressure Measurement System - A complete electronic measurement system based on powerful OxidataÖ software for Windows® 98 SE, 2000, NT, ME, and XP 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 box, OxidataÖ software CD, RTD probe assembly and connecting cables and hardware.
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 to K29300)
- Higher temperature models are available.
