LAB SAFETY SUPPLY® Vaneometer, Flowchecker™ and Calibration Kit

Determine and designate air velocities and airflows to ensure you have enough ventilation to eliminate airborne hazards.
Specifications: Durable Vaneometer™ measures air velocities from 25 - 400 lfpm (linear feet per minute). An inexpensive way to monitor fume hoods, glove boxes or safety chambers. Corrosion-resistant gauge can be read on both sides. Use as a portable meter or mount permanently on any flat surface for continuous readings. 4"H x 4"W x 1-1/2"D. Powder Puffer Bottle contains very fine silica powder that floats lightly on air to help you find leaks and check airflow patterns in hoods, ducts or rooms. Particle size is 0.007 microns.Ultralight Flowchecker powder floats lightly on air to help you find leaks and check airflow patterns in hoods, ducts or rooms. Nontoxic suspending agent remains airborne longer than ordinary powders, so you can accurately evaluate airflows. 1.5g squeeze bottles are easy to use. Polyester-laminated Face Velocity Labels help assure proper sash positioning. After you determine the sash position for 75, 100, 125 and 150 fpm, simply apply the appropriate label at that height. Package of 32 labels (4 each). 1"H x 2-1/4"W.
Calibration Kit Includes: Carrying case, instructions, Vaneometer, one package of Flowchecker and one package of Face Velocity Labels.
