Extech's compact thermo-anemometers and multifunction environmental meters couple all-in-one versatility with accurate diagnostics. CFM/CMM Mini Thermo-Anemometer with built-in InfaRed ThermometerLarge display of Airflow or Air Velocity with built-in InfraRed ThermometerThe Extech AN200 CFM/CMM Thermo-Anemometer measures airflow, air velocity, ambient temperature and has a built-in IR thermometer for measuring surface temperature. digital anemometer. The wire is usually made of tungsten, platinum or platinum-iridium [1]. Shop for Air Velocity Meters / Anemometers and other test & measurement instruments at Instrumart. Folds into handle to protect vane, as well as extends out of the. One will of-course be negative on the suction side, so you disregard that and make it positive, adding it to the exhaust value. This can be shown as a numerical readout. These include hot wire anemometers for low air velocities, rotating and swinging vane anemometers and variable area flowmeters. Turn on the meter using the ON/OFF button 2. Time and Weather > Anemometers > Extech AN300 Large Vane CFM/CMM Thermo-Anemometer; 4" vane allows for more precise readings on larger size ducts; Measure Air Velocity and Air Flow, Built-in thermistor for air temperature; Multipoint and timed average calculations; Dimensions 6" x 1. An air velocity meter or anemometer from Grainger can help measure wind velocity, air speed and other variables, such as air temperature, pressure, relative humidity and windchill factor. Airflow Meters Vane. Input the area of airflow measurement to gain accurate air velocity results. TWO APPLICATIONS: (1) HEATING and COOLING REGISTERS in Floor and Wall; (2) FLUE EXHAUST GAS SPEED Either Positive or Negative Pressure ADJUST AIR FLOW and FLUE EXHAUST SPEED, cfm Meter will measure So you Can Adjust your DAMPER. If measuring square duct work (in-duct or exit) you would enter Length and Width (LW). This is a replacement part for the Weather/Anemometer. units of measure are °F, ft/m (feet per minute), and cfm (cubic feet per minute). Available options include instruments that are intrinsically safe, waterproof, and explosion-proof. A wide variety of devices are commercially available for measuring air velocities. Be sure air temperature is stable before measurement. High sensitive and accurate thermo Anemometer. FPM to CFM Calculator: Usually, volume flow is measured in Cubic Feet per Minute, but at times we require to convert ft3/min to ft/min. The Extech AN100 thermo-anemometer offers simultaneous display of ambient temperature and air flow or air velocity. It can also track the maximum and minimum values along with current readings, displaying the flow rate in the user’s choice of meters per second or cubic feet per minute. The testo 405i Smart Probe hot-wire anemometer is a wireless instrument for measuring air flow velocity, temperature, and volume flow. Features:Has a low-friction, ball vane wheel design for accurate readings in both high and low air velocities. Both vane and hot wire technologies are available for nearly any application. Ultrasonic anemometer is used at weather stations, ship navigation sites, wind turbine sites, and in aviation and weather buoys to measure gas emissions and ecosystem fluxes. Turn on the meter using the ON/OFF button 2.
