New Air Velocity & IAQ Measuring Instrument from Testo
The testo 440 combines a compact handheld measuring instrument with user-friendly measurement menus and wireless probes – for the versatile and convenient measurement of all air conditioning and ventilation parameters.
To celebrate the company’s 60th anniversary, the measurement technology specialist Testo launches a new air velocity & IAQ measuring instrument in the market. The Testo 440 combines a compact handheld measuring instrument with user-friendly measurement menus and wireless probes – for the versatile and convenient measurement of all air conditioning and ventilation parameters.
As a market leader for portable and stationary measurement technology, Testo can look back on decades of experience in the development of cutting-edge products. Ventilation and air conditioning solutions from the Black Forest German company are in use all over the world, wherever a pleasant indoor climate and optimally adjusted ventilation systems are crucial: In offices and residential buildings as well as in laboratories or industrial production halls.
In this sector, Testo is extending the breadth of its range with the new air velocity & IAQ measuring instrument Testo 440. The innovation combines everything which makes the air velocity & IAQ measurement technology so successful – intuitive operation, precise measurement values and an extensive probe range – and extends these advantages by wireless convenience.
Intuitive Measurement Menus
The measurement of air velocity & IAQ and comfort parameters often takes place according to standardized procedures and norms. In order to simplify work for the user, clearly structured menus for the following measurements are pre-set in the testo 440: Volume flow measurement in ducts and at outlets, k-factor, degree of turbulence according to EN ISO 7730/ASHREA 55, cooling/heating load, mould indication and long-term measurement (recording of measurement values at set intervals).
More Applications with less Equipment
The Testo 440 probes are available for air velocity, temperature, humidity, degree of turbulence, CO2, CO and light intensity. Customers have the choice between wireless and fixed-cable models. The wireless Bluetooth® probes ensure more freedom of movement in measurement and save space in the measurement case. In addition to this, a probe handle can be universally combined with all corresponding probes and probe attachments. This allows you to switch in seconds from indoor air quality measurement to a determination of volume flow at a vent.
Clear, reliable and secure
The large display of the Testo 440 shows up to 3 measurement values simultaneously. It also allows easy configuration of the measurements as well as a view of results at a glance. The instrument’s memory can record up to 7500 measurement protocols.
Kits and Model Versions
The Testo 440 multi-function measuring instrument is available in two versions. The model testo 440 dP is technically identical to the regular version, however, it has an additional, integrated differential pressure sensor. This makes measurements at filters as well as Pitot tube and k-factor measurements possible. Pre-configured kits consisting of measuring instruments, probes and accessories are available for the most important areas of application (incl. ducts, vents, indoor air quality and ventilation/air conditioning measurements in laboratories).
