		Air Velocity Meter Measure both pressure and air velocity Read the red figures directly in feet per minute of velocity - from 400 to 10,000 fpm No conversion tables needed for air at standard conditions. Read the black figures in inches of water column air pressure - from 0 to 10" w.c. Our most popular precision air velocity instrument, the No. 400 is used to balance air conditioning systems, measure pressure drop across filters, and test fan and blower discharge and inlet pressures, as well as air velocity in ducts. It offers the convenience of a dual purpose instrument - plus high accuracy on easy-to-read scales. A versatile, all around manometer for the air conditioning and balancing contractor or industrial plant. Request Quote View Literature

		Series MVT - Mini-Vane Thermo-Anemometer Display Air Flow, Air Velocity and Temperature, Telescoping Mini-Vane, RS232 Output Sense air velocity, air flow and temperature with the Series MVT Mini-Vane Thermo-Anemometer. The meter uses a 1/2" (12.7 mm) diameter metal telescoping antenna sensor to detect air flows up to 2358 ft/min and temperatures to 176°F (80°C). High accuracy is ensured with the low friction ball bearing mini-vane. Air flow can be measured in CMM (m³/min) or CFM (ft³/min) and temperature is selectable °F or °C. The MVT features a 4-digit LCD display, data hold, record/recall maximum and minimum, RS232 output, averaging up to 20 measurements, 2/3 the measured value and auto shut-off to prolong life. The unit includes telescoping mini-vane probe, hard case, 9V battery and protective rubber holster with stand. Request Quote View Literature

		Model VT120 - Integral Vane Thermo-Anemometer Large 1-1/4" Dual Display, One Hand Operation Simultaneously measure air velocity and temperature with the Model VT120 Integral Vane Thermo-Anemometer. Easily view readings on the large 1.25" (31.15 mm) dual display. User-selectable air velocity ranges include ft/min, m/sec, mph, knots, and km/hr. Built-in thermistor records ambient temperature in °F or °C. Model VT120 features include data hold and record/recall minimum, maximum and average readings. Also, units have the ability to record and average up to 2 hours of data while displaying the continuous running average. If desired, sleep mode automatically shuts down the meter after 20 minutes of non-use. Model VT120 includes hard carry case, one 9V battery, and instruction manual. Request Quote View Literature

		Model VT-200 - Vane Thermo-Anemometer Measures Air Volume, Air Velocity and Temperature, Built-in Datalogging Model VT-200 Vane Thermo-Anemometer is ideal for balancing air conditioning and heating ducts or checking the operation of fans and blowers. Model VT-200 measures air volume in cubic feet per minute and cubic meters per minute. Air velocity measurements can be viewed in ft/min, m/s, knots, km/hr, and mph with ±3% accuracy. The multifunction LCD can simultaneously display air velocity and temperature in selectable units or air flow and air area. Built-in datalogger can store up to 1000 measurements or transfer the data to a PC via RS-232 communication. Additional features include data hold and record/recall minimum, maximum and average readings. Model VT-200 includes RS-232 interface, PC Windows software, cable, 9V battery, carrying case, and instruction manual. Request Quote View Literature

		Model 470-1 - Handheld Thermal Anemometer Measures Air Velocity to 6,000 FPM, ±5% Accuracy, Low Cost The versatility of the Dwyer Model 470-1 Handheld Thermal Anemometer makes it ideal for a wide range of air velocity measurements. Easy to carry and use in the field, the 470-1 can be used to balance heating and air conditioning systems, measure velocity in HVAC ducts, read fume and exhaust hood face velocities, as well as make wind speed measurements associated with agricultural, forestry, highway and recreational activities. This low cost battery powered electronic instrument features an LED low-battery indicator and provides two switch selected air velocity ranges of 0-600 FPM and 500-6000 FPM displayed on an easily read analog meter. Sophisticated temperature compensation circuitry maintains ±5% of full range accuracy over an air stream temperature of 30 to 180°F. Included are two 9 volt alkaline batteries, a wrist strap for the unit and a durable polypropylene, foam-lined carrying case. Request Quote View Literature
