In order to establish whether an air conditioning or ventilation system is functioning properly, among other things you need to check the flow speed or the volumetric flow in the ventilation duct. If the air flow velocity is too low, the room loads are not correctly discharged and optimum room air quality can no longer be guaranteed.

testo 425 air velocity meter for quick, easy flow measurement

The testo 425 air velocity meter enables quick spot measurements in ventilation ducts. It records the flow speed, calculates the volumetric flow and also measures the temperature. With a measuring range of 0 to +20 m/s, this air velocity meter is particularly well suited to low air flow velocity.

The air velocity meter features a telescopic flow probe. The telescope can be extended to a length of up to 820 mm and has a probe head diameter of 7.5 mm.

Like the flow speed, would you also like to detect the volumetric flow on your air conditioning or ventilation system? This is no problem for the testo 425 air velocity meter. When you input the duct surface area, it automatically calculates the volumetric flow during the flow measurement. Single and multi-point averaging provides an indicator of the average volumetric flow, flow speed and temperature reading.

You can read off the current readings and the min/max and calculated mean value at any time on the illuminated display. Using the Hold button, you can freeze the current reading in order to compare it with another value, for example. If you should ever forget to switch off the air velocity meter, the Auto-off function will take care of this for you. This conserves your batteries and ensures that your air velocity meter is ready for use in the next measurement.

Equip yourself with accessories for the air velocity meter

To make sure that you are well-prepared for any circumstances, we recommend that when purchasing the air velocity meter, you also order our practical accessories: as an added option we offer a handy pocket, a transport case and also the TopSafe protective cover (to protect the air velocity meter from water, dirt and impacts).

The anemometer has a permanently mounted vane with a diameter of 40 mm. You can therefore use it for the integral measurement of air velocity at ventilation grilles (air outlets).
The anemometer is practical for outdoor operation: It not only measures air velocity and air temperature, but also calculates the Beaufort wind force and the wind chill temperature, which is the temperature perceived by a person due to wind-related cooling.

The vane anemometer with practical functions

The testo 410-1 includes a plug-on protective cap, as well as a wrist strap for secure measurement, and enables you to take advantage of the following functions:
Single-point averaging: The anemometer provides information on the average air velocity, e.g. at air outlets
Hold function: is used to record the current values relating to air velocity and air temperature and compare them with each other
Max/min values: get the minimum or maximum values since the anemometer was last switched on or reset, at the touch of a button
Illuminated display: read off your readings even in dark environments
Selectable units: for air velocity and temperature: m/s, km/h, fpm, mph, kts, Beaufort, °C, °F and wind chill

testo 417 vane anemometer with integrated 100 mm vane, calibration protocol, battery.

APPLICATION:
Every duct inlet and outlet should only contain the volumetric flow that according to calculations is a basic prerequisite to an efficient functional system.Particularly large vane anemometers are suitable for measuring the volumetric flows at duct outlets, as these integrate the flow velocity over a larger area thereby determining disturbance from the air grille (loop method).A volumetric flow rate funnel and a large vane are ideal when taking readings at the suction or blowing vents of air grilles and poppet valves. The entire volumetric flow is recorded with the aid of the funnel without the need for conversion on the basis of the flow velocity and area. This method of flow measurement is simple and reliable.The compact anemometer testo 417 with integrated flow/temperature vane (Ø 100 mm) is ideal for measuring the flow velocity, volumetric flow and temperature at duct outlets. The optional funnel set allows measurements at ventilation grilles and poppet valve

If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then testo 405 thermal anemometer is a must-have. The thermal anemometer features a permanently mounted telescope and enables you to measure air flow, volumetric flow and air temperature. The measuring range for flow is between 0 to 10 m/s, volumetric flows are calculated up to 99,990 m3/h.

The extendible telescope (up to 300 mm) makes the thermal anemometer particularly suitable for flow measurements in ventilation ducts. The illuminated display can be swivelled into various positions, ensuring that the readings can be read off comfortably. The duct bracket (included in the delivery) offers key practical advantages. You can use this to optimally position the telescope in the ventilation duct and obtain precise measurement results.

Since the thermal anemometer testo 405 measures particularly accurately in the range between 0 and 2 m/s, you can also use it to measure the air velocity in rooms for checking indoor air quality. Low air velocities, at draughty windows for example, are quickly located and accurately measured using the thermal anemometer.

Integrated sensor protection: when you are not using the testo 405 thermal anemometer, the rotating protective cap protects the flow sensor from mechanical stress.

APPLICATION:
For workers to feel comfortable in their indoor working environments, "thermal comfort" has to prevail. The EN 13779 describes this as a state that prevails when people are satisfied with the air temperature, humidity, air movement and thermal radiation in a room, and require neither hotter, colder, nor drier or more humid indoor air.

The testo 405 is particularly well suited to measuring indoor flow velocity. Low air velocities, such as at draughty windows, can therefore be precisely located and measured extremely accurately
