' The Alnor Velometer is an instantane ous, direct-reading air velocity meter designed for convenient, rapid deter mination of air velocities in air condi tioning, heating and ventilating, and exhaust systems. It gives instantaneous direct readings in feet per minute, with out timing, calculations, or reference to tables or charts. Accurate information on performance of equipment,^ duct sys tems, etc., can be obtained with a few moments inspection with the VELOM ETER. It can be effectively used to locate drafts and leaks around windows and doors, or in duct systems. Alnor Velometer, Jr. A miniature, di rect reading Velometer--4 in. high, 3 in. wide, 1-1 in. deep.
