Step 4:You can read the result value on the scale. Step 3:Adjust the eyepiece to the clear state. Step 2:Cover the prism, look through the eyepiece against the light. Step 1: Place a few drops of the liquid on the main prism.
The body is mainly made of metal with silica gel cover.Īutomatic temperature compensation (ATC): 10☌ ~ 30☌ (50☏ to 86☏) The measurement is more accurate with Automatic Temperature Compensation.Ĥ. The refractometer is delicate for being made of copper plating.ģ.
The scale is clear with the imported lens.Ģ. The horizon is clearer for the upgrading of lens.ġ. The body is of high quality for being made of copper plating. The wide cover plate guarantees the perfect match with the lens. The internal is built with optical glass lens. The body of refractometer is designed with streamline shape. Packed with features including airflow calculation, automatic average, detection of flow direction and, hold/minimum/maximum functions, the VT110S makes wind velocity measurements easy.Īpplication: Areas with relatively constant temperature such as indoor environments checking flow hoods, HVAC systems, and exhaust monitoring.Brix 0-32% Handheld Refractometer Sugar Brix Auto Refractometer with ATC The VT110S Hot Wire Anemometer can measure air velocity, temperature, and airflow. The meter will then measure how much current was needed to keep the wire at a constant temperature and simultaneously convert this metric to an air velocity reading. The device will try and keep the wire at a constant temperature while any air flowing past will start to cool it. They use a fine wire heated a few degrees above the ambient temperature. Hot Wire Anemometers measure wind speed using the principle that the colder impact of wind flow extracts heat. Outstanding Features: Conforms to EMC 2004/108/CE and EN 61010-1, is supplied with a 100mm vane probe, and the coiled sensor cable makes for ease of use.Īccuracy: From 0.3 to 3 m/s : ☓% of reading (☐.1 m/s) From 3.1 to 35 m/s : ☑% of reading (☐.3 m/s) The LV110S is by far our most popular Vane Anemometer for HVAC systems! It features a 100mm wired probe, calculates airflow, automatically averages wind speed, and detects flow direction.Īpplication: This anemometer is perfect for HVAC systems, monitoring exhaust flow and, exhaust hoods (Unlike cup anemometers) vane anemometers must be faced in the direction of a wind source to obtain accurate data. The device measures each time the magnetised blade passes the reed switch within a specific timeframe and converts this to a windspeed measurement. For example, a propeller blade may have a magnet that passes by a reed switch each time the turbine spins. Vane anemometers measure wind speed using propellers or turbines. Outstanding Features: Water-resistant indoor LCD screen, 1000 hour battery life, broad measurement range, mounting bracket included.Īccuracy: 0.8 km/h from ~6.4 to 16 km/h ±4% from 16 to 80.4 km/h estimated within 4% above 80 km/h Perfect for mounting on the roof of your home, business, or school. It is an inexpensive way to provide you with accurate wind speed in places where AC power may not be available.Īpplication: Built to measure outdoor wind speeds where accuracy is important, and AC power is lacking. The Vortex-P-30 is a tough instrument designed to measure wind speed from 4.8-200 km/h. A hall effect sensor or reed switch measures the number of rotations in a time frame and converts the rotation measurement into a wind speed metric.
As the wind velocity increases, the cups spin freely. Measuring wind velocity where the source is inconsistent andĬup anemometers generally consist of three cups attached to horizontal arms mounted on a vertical rod.Householders, businesses, and professionals commonly use anemometers for: To help make things easier, this article outlines four main types of anemometers, provides some product examples, along with recommended applications. Temperature-Humidity Cabinets AccessoriesĪn anemometer is a device used to measure wind speed for a variety of applications, including for sporting events and HVAC system troubleshooting and monitoring.įinding the right anemometer for your specific needs can often be an arduous task.
