FEATURED KOEHLER HPM TESTING PRODUCT

Low Temperature Torque Apparatus

HPM   |   HPM + LT

Refrigerated two-unit apparatus for ASTM low temperature torque tests on lubricating greases. Includes an insulated, thermostatically controlled air chamber with test rigs, drive shafts and externally mounted gear motors. Rotates drive shafts at 1rpm while electronic load cell-strain gauge indicators measure the torque required to restrain the test rigs. Digital LED displays indicate torque for each drive unit and cold chamber temperature.

On ASTM D4693 models, the spindle temperature is also indicated for each drive unit. Includes drive shaft overtorque protection—when drive shaft torque exceeds a preset value, the drive motors automatically shut down to prevent breakage of shaft insulators.

 


ALL KOEHLER HPM TESTING PRODUCTS

HPM

Digital Penetrometer

Microprocessor-based penetrometer loaded with advanced features to provide ease of operation and highly reproducible consistency measurements of petroleum products as per ASTM D217.

HPM

Oxidation Stability Test Apparatus for Lubricating Greases

Constant temperature oil bath holds pressure vessels at the proper depth for determining oxidation stability of lubricating greases as per ASTM D942.

HPM

Water Washout Tester

Rotates a lubricated ASTM ball bearing at 600rpm in a modified bearing/housing assembly while impinging the bearing with a jet of water at the specified flow rate and temperature as per ASTM D1264.

HPM

Low Temperature Torque Apparatus

Significant for the design and specification of greases for low temperature service, the low temperature torque test measures the extent to which a grease sample retards rotation of a bearing assembly at the test temperature as per ASTM D1478.

HPM

Oil Separation Apparatus – Constant Temperature Air Cabinet

Determines the tendency of a lubricating grease to separate oil during storage in a 35 lb pail as per ASTM D1742.

HPM

Oil Separation Apparatus

Consists of 60 mesh nickel gauze cone with wire handle, tall form 200mL beaker and cover with hook. The sample is placed in the wire gauze cone and weight loss is determined after heating at test temperature for specified time period as per ASTM D6184.

HPM

Roll Stability Tester

Roll stability apparatus for shear stability tests on lubricating greases. Rotates steel test cylinders at 10 or 165rpm in a thermostatically controlled environment at temperatures of up to 200°F (93.3°C) as per ASTM D1831.

HPM

Benchtop Four Ball Wear and EP Tester

The 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 under a variety of test conditions as per ASTM D2266 and D2596.

HPM

Corrosion Preventive Properties Apparatus

Distributes a lubricating grease sample in a roller bearing by running the bearing under light thrust load. Corrosion preventive capability is determined on a pass/fail basis by the presence of rust spots (1mm or larger) on the bearing race after a 60 second run-in period followed by prolonged exposure to water at constant temperature as per ASTM D1743.

HPM

Corrosion Tester

The Corrosion Tester K9445X has been developed for testing lubricating greases on their corrosion inhabiting characteristics in rolling bearings in the presence of either distilled or demineralized water, or salt water or synthetic sea water and under no applied load as per ASTM D6138.

HPM

Copper Strip Corrosion from Lubricating Grease

Constant temperature bath immerses 16 test jars for lubricating greases as per ASTM D4048.

 

HPM + WR

Water Washout Tester

Rotates a lubricated ASTM ball bearing at 600rpm in a modified bearing/housing assembly while impinging the bearing with a jet of water at the specified flow rate and temperature as per ASTM D1264.

HPM + WR

Water Spray Apparatus

Complete Water Spray Apparatus meets ASTM specifications and includes spray chamber, delivery system and constant temperature reservoir. Sprays water at the specified rate and temperature on a test panel coated with sample grease as per ASTM D4049.

 

HPM + CR

Corrosion Preventive Properties Apparatus

Distributes a lubricating grease sample in a roller bearing by running the bearing under light thrust load. Corrosion preventive capability is determined on a pass/fail basis by the presence of rust spots (1mm or larger) on the bearing race after a 60 second run-in period followed by prolonged exposure to water at constant temperature as per ASTM D5969.

HPM + CR

Corrosion Tester

The Corrosion Tester K9445X has been developed for testing lubricating greases on their corrosion inhabiting characteristics in rolling bearings in the presence of either distilled or demineralized water, or salt water or synthetic sea water and under no applied load as per ASTM D6138.

 

HPM + HL

Benchtop Four Ball Wear and EP Tester
