Benchtop Four Ball Wear and EP Tester
$14,000.00The K93170 Four Ball Wear and EP Tester is designed as per ASTM standards to conduct tests to determine the coefficient of friction of lubricants, wear preventative (WP) and extreme pressure (EP) properties of lubricating oils and greases under a variety of test conditions. This instrument can also be used to determine load carrying properties by the load wear index and the weld point method.
The test load is directly controlled through a software-based close loop servo-pneumatic drive, which enables precise control over the load application. The user can choose between different loading sequences, such as constant load test, progressive loading in increment or decrement, and also step-wise loading in increment or decrement. This dynamic load control system with speed control can also be used for understanding the Stribeck curve phenomena, which is not possible with the conventional dead weight loading technique.

Combination Octane Rating Unit Engine
$23,000.00The K90901 Standard Model Combination Octane Rating Unit is the latest model of octane engines with many easy-to-use features including automatic functions and enhanced documentation capabilities, conforming to the latest ASTM D2699 (RON) and ASTM D2700 (MON) test methods.
Through the engine’s operating panel, the parameters are adjustable according to the ASTM D2699 and D2700 specifications. The professional and clear design of the operating area makes the octane rating operation convenient and the data is easy to read and record. The auto-setting function of the octane engine effectively simplifies operational procedures and improves the efficiency of octane testing. The operating panel is equipped with a protect system and push-button switches to avoid improper operation.

Oxidation Stability Apparatus, 8-Place and 12-Place Bath
$22,000.00Constant temperature bath with solid state temperature control, calibrated flowmeters and condenser water manifold for oxidation stability tests on fuels and lubricants. Individual flowmeters and control valves for each oxidation cell deliver air flow at the rate of 3L/h. Condenser water manifold has individual control valves for each cell. Temperature 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. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Double-wall insulated baths are equipped with copper immersion heaters and a 1⁄20 hp circulation stirrer. Stainless steel bath interior has a builtin support rack and overflow/drain to immerse the test cells at the required depth. Order oxidation cell glassware and accessories separately.

Oxidation Stability Test Apparatus for Lubricating Greases
$22,000.00Oxidation 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
