Product#: TG-6999 Availability: This item normally ships within 1 - 2 business days. Description: For use in obtaining kinematic viscosities. ASTM Method of Test D445. Viscosity ranges shown below are for a lower efflux time of 200 seconds. For size 25, minimum time for 0.5 cs viscosity should be 250 seconds. Kinetic energy correction is negligible when these times are held. Uncalibrated and supplied without certificates.
