Controls and Instruments Illinois Testing Laboratories, Inc. Room 51G, 420 N. La Salle St., Chicago 10, 111. Precision Instruments for Every Industry The direct-reading ALNOR VELOMETER B 1 .-'S 4 TYPE 4-P Standard minimum set for heating and air conditioning air velocity mcaeuremente. 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-i in. deep. Weight, 8 oz. Accu rate, strong. Available in single and double scale ranges: 0-200 to 0-2500 fpm. Bulletin 725. The Alnor Velometer is built in several standard ranges from 20 fpm to 6000 fpm, and up to 3 in. static or total pressure. Special ranges available as low as 10 fpm and up to 25,000 fpm velocity and 20 in. pressure. Alnor Thermo-Anemometer. For accu rate measurement of low air velocity. Compact, direct-reading, battery oper ated, self-contained, portable. Scale 6 in. Meter ranges: 0-600 fpm and double range 0-300/100-2000 fpm. Accurate readings as low as 5 fpm.
