YR-1 Yield Rheometer Finally a Yield Test Rheometer for QC! The YR-1 is a revolutionary, simple-to-use, low-cost alternative to complicated, full-featured laboratory rheometers. It's designed to be used right on the production floor by your technicians. Simply select a test, lower the vane spindle into the product, press "GO", and the instrument displays the result in a single shear stress number for your material's yield value. It couldn't be easier! Features And Benefits Simple to use Use in the QC lab or on the production floor Excellent repeatability Traditional Brookfield quality Affordable Built-in RTD temperature probe Complete with vane spindles Complete with EZ-Yield software Parallel printer, serial RS-232, and analog voltage outputs Ranges Spindle Torque Range Shear Stress Range (Pa) V-71 RV 0.5 - 5 V-72 RV 2 - 20 V-73 RV 10 - 100 V-71 HB 4 - 40 V-72 HB 16 - 160 V-73 HB 80 - 800 V-71 5xHB 20 - 200 V-72 5xHB 80 - 800 V-73 5xHB 400 - 4000 NOTE: 1 Pa = 10 dynes/cm² Spindle Dimensions Spindle Vane Length Vane Diameter V-71 2.708 in./6.878 cm 1.354 in./2.167 cm V-72 1.706 in./4.333 cm 0.853 in./2.167 cm V-73 0.998 in./2.535 cm 0.499 in./1.267 cm NOTE: Sample container diameter should be twice (2x) the vane diameter when possible. Sample container depth should provide clearance at the bottom equivalent to vane spindle diameter when possible.
