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 m/s
Telescope extendible to 300 mm

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, e.g. at draughty windows.

Product Description:
If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then our testo 405 thermal anemometer is a must-have. The 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 testo 405 thermal anemometer measures particularly accurately in the range between 0 and 2 m/s, you can also use it to measure the air velocity in rooms. Low air velocities, at draughty windows for example, are quickly located and accurately measured using the 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.

Vane anemometer with permanently installed 40 mm vane
Measurement of air velocity and air temperature
Calculates wind chill and the Beaufort wind force
Practical: with single-point averaging, max/min and Hold function

The testo 410-1 vane anemometer measures air velocity and air temperature. Use it to carry out quick spot measurements at ventilation grilles (air outlets). The anemometer is also ideal for use outdoors. It displays the units m/s, km/h, fpm, mph and kts, and also calculates wind chill and the Beaufort wind force.

Product Description:
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 m/s, 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: as well as air velocity and air temperature, the testo 410-1 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: 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

Calculates the dew point
Ideal for measurements in ventilation ducts and in rooms
Measuring values easy to read off thanks to a pivoting display

The testo 605-H1 thermohygrometer enables reliable measurement of humidity and air temperature and calculation of the dew point. It has a permanently mounted probe shaft which means it is excellent when it comes to carrying out check measurements in ventilation ducts.

Product Description:
If you are looking for a compact, user-friendly thermohygrometer, the testo 605-H1 is the ideal choice. It measures relative humidity and air temperature and also calculates the dew point in the -20 to +50 °C td range. The built-in Testo humidity sensor ensures reliable measurement results with long-term stability.

The thermohygrometer is suitable for check measurements in production, storage, office and server areas. The testo 605-H1 is particularly practical for measurements in ventilation ducts, because it has a permanently mounted probe shaft (length: 125 mm). The bracket which is also supplied enables you to position and fix the probe shaft in the desired location in the ventilation duct. This means you can carry out your measurements without having to hold the thermohygrometer while doing so.

The design of the testo 605-H1 temperature and humidity measuring instrument has been well thought through, right down to the details: the display can be pivoted into different positions, enabling the measuring values to be read off easily. When you are not using the testo 605-H1, the rotating protective cap at the end of the probe shaft protects the sensor from mechanical stress.
