MRV TP-1 Mini-Rotary Viscometer

ASTM | D3829 | D4684 | D6821 | D6896

Low-Temperature Pumpability & Yield Stress: A pre-heated oil sample is cooled at a programmed rate to a final test temperature. A series of increasing low torques (weights) are applied to the rotor shafts until rotation occurs to determine the yield stress, if any exhibited.
Higher weight applications then determine the apparent viscosity of the samples. The MRV methods are applied to fresh and used engine oils, driveline lubricants, and predict the borderline pumping temperatures (BPT) of oils.

Description

Features:

An internal hermetic refrigeration system for direct, instant cooling with no need for
external refrigeration or heat exchangers.
· Customizable with 5 to 10 removable test cells for easy cleaning and sample handling.
· Carbon Fiber Rotor Shafts to minimize test cell heat transfer.
· A quick cool rate and reliable temperature control from -5°C to -40°C (±0.1°C).

Built-in pre-heating system to 80°C to remove oil memory before testing.
· Microprocessor temperature controller to store all MRV TP-1 testing profiles.
· Optical encoder for digital detection of viscosity and yield stress
· MS Windows 10® compatible software with customizable cooling profile
configurations.
· Internal system to provide a continuous blanket of dry gas over samples to
reduce/eliminate moisture accumulation (gas source not included).
