Marsh Funnel -Drilling Mud Testing - Drilling Fluid - Viscosity Funnel-OFI Brand

Description

14" OFI brand Marsh Funnel, used primarily for measuring the viscosity of Drilling Mud-Drilling Fluids.
It's used but hasn't seen much field use. This is a very durable brand of funnel. I have another one like it that I've used for more than 30 yrs in the Texas oil fields.
Tested for accuracy and it's calibrated & measures clear fresh water precisely @ 26 seconds per quart.
Funnel ships with tracking, usually the next business day after payment has cleared.
U/S Sales only.
