Product Description
***this is specifically for ASTM D1478. request pricing on one of the models listed below for other options***
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.
Features and Benefits:
~ Digital torque indication for two samples
~ Choice of test rig combinations
~ Mechanically refrigerated, with standard -65°F (-54°C) operating range
~ Optional cooling range to -100°F (-73°C)
~ Optional strip chart recorder or data acquisition software
~ Data acquisition software available
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, spindle temperature is also indicated for each drive unit. An optional factory installed strip chart recorder provides a hard copy record of starting torque, running torque and maximum torque. 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. Standard cooling range of -65°F (-54°C) meets ASTM requirements for D1478 and D4693 test methods. Optional -100°F (-73°C) range is available for special testing requirements.
