The testo 410-1 vane anemometer is impressive thanks to its practical pocket size and is ideal for fast check measurements. With a measuring range of 0.4 to 20 ms, the anemometer can even be used for low flow speeds. 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 Maxmin 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: ms, kmh, fpm, mph, kts, Beaufort, °C, °F and wind chill

Resolution : 0.1 m/s

Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms for indoor air quality, e.g. at draughty windows. Product benefits: Measurement of air velocity, volumetric flow and air temperature For measurements in ventilation ducts and in rooms Particularly precise in the range between 0 and 2 ms Telescope extendible to 300 mm Product description 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 ms, volumetric flows are calculated up to 99,990 m3h. 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 ms, 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.

Leaks on a refrigeration system have very serious consequences: the required cooling capacity is reduced and, in the worst case scenario, the system may suffer damage. This can cause environmental damage and result in unnecessary cost to your customer. This makes it all the more important for you to be able to detect even the smallest of leaks quickly and reliably – using the testo 316-4 leak detector, for example.

The testo 512 with a measuring range from 0…200 hPa can be used to help you carry out quick and easy filter checks when performing differential pressure checks on ventilation and air conditioning systems. Differential pressure measurements are carried out to determine whether filters still work properly or whether they are used up and clogged and need to be replaced. The differential pressure meter is ideal for carrying out pitot static tube measurements in air ducts at very high air flow speeds or when the air stream is strongly polluted. The compact, rugged meter shows both the pressure as well as the air flow speed and has a measuring range from 10 to 100 ms. The damper for adjustable averaging can be programmed individually while the density compensation is already integrated. The pitot static tube that you will need to carry out your air flow measurements can be ordered together with your differential pressure meter. Choose from one of three models to select the model that is best suited to your individual requirements. The pitot static tube is inserted into the air duct where it measures the air flow quickly and reliably. The testo 512 displays the pressure and the air flow speed simultaneously. You can choose between two different units of measurement - ms and fpm - to indicate the air flow speed and from eight different units - psi, kPa, hPa, Pa, mm H2O, mmHg, inch H2O and inch Hg - to measure the pressure.
