The testo 417 vane anemometer allows you to measure air flow speed, volumetric flow rate and temperature simultaneously. The integrated vane makes it ideal for carrying out measurements at air inlets and outlets. The optionally available testovent 417 funnel set allows you to carry out measurements at ventilation grilles and disk valves. There is also an air flow rate rectifier for carrying out quick and reliable measurements at diffusers.The vane anemometer is designed to provide you with the following valuesThe easy-to-read display shows all important data including air flow direction - ie. whether the air is being sucked in or blown out - air flow speed and the volumetric flow rate as well as the actual temperature.The mean time value and average value provide you with information regarding the average volumetric flow rate, air flow speed and the temperature measurement. In order to carry out the volumetric flow rate simply enter the area of the duct or use the optionally available funnel set.   In addition, there is also a hold function which allows you to compare the measurement you have just take with previous measurements. Min and max values are also available at the touch of a key. And thanks to the testo 417’s backlit display you can read the measurements in the dark or in poor lighting. Product Includes: testo 417 vane anemometer with integrated 100 mm vane, calibration protocol, battery.Measurement of volumetric flow, flow velocity and temperature 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 valves.

-Has a built-in 40mm vane sensor.-With computation function for sensible temperature (wind chill). -Measures hot wind at vent outlet and hot wind speed of duct.

With the compact 16 mm vane anemometer testo 416 with telescopic probe and App connection, you can carry out flow measurements in the ventilation ducts of air conditioning and ventilation systems easily, quickly and precisely. The integrated telescope can be extended up to 850 mm, making it easier to work overhead or in large diameter ducts. To ensure that you have all the relevant information at your fingertips, the testo 416 automatically calculates time and point average values as well as the volume flow rate. And thanks to the compact design and the robust housing, the vane anemometer can also stand it if conditions get a little rougher at times. Configuration of the measuring instrument, display and storage of measured values as well as documentation are all particularly convenient with the testo Smart App. This also turns your smartphone into a second display.

This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres.Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit your vane probe (Ø 100 mm) with the telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately).Greater freedom thanks to Bluetooth: the air velocity probes with Bluetooth have no inconvenient cable connection to the measuring instrument, and they transmit readings up to a distance of 20 m. Press the button on the probe to operate the measuring instrument – for example, to start and stop a series of measurements (timed mean calculation).Attach the testo 440 dP air velocity and IAQ measuring instrument to metal surfaces (e.g. ducts) easily using the practical magnets.Benefit from fast calculation of the volume flow: in the "volume flow” measurement menu of the multifunction measuring instrument, configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away. Long-term monitoring of indoor air quality Poor indoor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. With its menu for recording readings, the testo 440 air velocity and IAQ measuring instrument is ideal for monitoring the indoor air quality. Enter the measurement time and the measuring cycle – and, for example, track the change in CO2 concentration or humidity and temperature values over the course of the day. Simply choose between probes with Bluetooth or fixed cable for CO2, CO or humidity (please order probes separately). Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55 Determine the degree of turbulence and the draught risk in the workplace: draught restricts the comfort level and is the most common cause of complaints about the indoor climate. The turbulence probe (please order separately) measures air velocity and air temperature, and automatically calculates the draught risk and the degree of turbulence in accordance with EN ISO 7730/ASHRAE 55.For convenient measurements at varying heights, we recommend using our measuring tripod for comfort level measurement (please order separately). This makes it very easy to position turbulence probes in compliance with the standards. Range of probes for cleanrooms and laboratories The testo 440 air velocity & IAQ measuring instrument is also ideal for a wide variety of applications in cleanrooms and laboratories in conjunction with the following probes: High-precision flow measurement in fume cupboards with the fume cupboard probeThanks to the low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for laminar flow measurements in cleanrooms. It is available as a variant with Bluetooth or with fixed cableTo measure the humidity in cleanrooms, we recommend the high-precision humidity/temperature probe (0636 9771 or 0636 9772). With an accuracy of ±(0.6 %RH + 0.7% of m.v.) (0 to 90 %RH), it also meets the requirements for humidity measurements in this particularly sensitive areaUse the high-precision digital Pt100 temperature probes, for example, for high-precision comparative measurements in calibration laboratories, temperature measurements in chemical laboratories or in the cosmetics industry as well as for determining the temperature distribution in refrigerators and conditioning cabinets
