PRI-T-HOOK Shepherd’s Hook Thimble Holder for Vertical Sampling
The PRI-T-HOOK Shepherd’s Hook Thimble Holder assembly is designed for sampling when there is a horizontal flow. The S type pitot and the nozzle are inserted into the stack vertically to maintain an isokinetic state during the capture of particulates. (click on image to enlarge)
For vertical sampling, our PRI-T-HOOK is the ideal accessory to orient the thimble filter in an upright position, thus permitting gravity to assist the sample vacuum in keeping the particulate catch in the filter. The thimble holder is designed to hold a 30x100 mm filter (not included).
