Testo 440 Air Velocity and IAQ Tester Description

The Testo 440 Air Velocity and IAQ Tester is an accurate, adaptable and easy-to-use multifunctional measurement instrument. It can be combined with an array of compatible OPTIONAL Testo probes (the hot wire probe is the ONLY probe included in this kit) in order to measure a variety of environmental parameters such as:

• Volume of flow in ducts/ outlets
• Funnel measurements
• Degree of turbulence
• Cooling/ heating output

This instrument can also be used to locate mould. All of the aforementioned measurements and functions are easily accessible via the Testo 440 Air Velocity and IAQ Tester’s clearly structured measurement menu. Furthermore, the Testo 440 Air Velocity and IAQ Tester will automatically identify the detected probe and will adjust its measurement parameters accordingly, thereby improving both the ease and efficiency of testing.

Additionally, as the Testo 440 Air Velocity and IAQ Tester recognises the connected probe and adjusts the parameters accordingly, the probes are the only items that require calibration. This reduces calibration costs and allows the user to keep the Testo 440 Air Velocity and IAQ Tester in continuous use thereby reducing losses caused by downtime.

It is possible to connect up to three probes to the Testo 440 Air Velocity and IAQ Tester at any one time; for instance, the Testo 440 Air Velocity and IAQ Tester can accommodate a Bluetooth Probe (NOT included), a wired probe (hot wire probe included), a temperature probe with a type-K thermocouple connector (NOT included).

The Testo 440 Air Velocity and IAQ Tester can be used with Bluetooth probes to conduct measurements up to twenty metres away from the Testo 440, eliminating the need for long cables and adding to the practicality of this instrument. It is also possible to send data to print using the Testo 440 Air Velocity and IAQ Tester’s Bluetooth capabilities and a compatible Testo Bluetooth/ IRDA printer.

Data is saved to the Testo 440 Air Velocity and IAQ Tester’s internal memory, which has the capacity to store up to 7500 measurement protocols. Data can be exported to a PC using a USB cable. Once uploaded onto a PC, collected data may be processed as a CSV file.

It is also possible to view data via the Testo 440 Air Velocity and IAQ Tester’s large, graphic display capable of indicating three readings in parallel. The inclusion of magnets means that the Testo 440 Air Velocity and IAQ Tester can be held in an easy-to-see place throughout the measurement period, freeing the user’s hands for conducting measurements using the probes.

These magnets also prove particularly useful when conducting long-term measurements. The user is able to enter the measurement period and intervals into the Testo 440 Air Velocity and IAQ Tester, allowing him/her to monitor measurements over long periods of time.

It is also possible to enter the dimensions and geometry of a duct’s cross-section into the Testo 440 Air Velocity and IAQ Tester, thereby allowing the user to view the volume flow instantly via the display. Again, this improves testing efficiency and ease.

When used with a compatible turbulence probe (NOT included), the Testo 440 Air Velocity and IAQ Tester is able to measure turbulence in accordance with EN ISO 7730/ ASHRAE 55, even in low air velocities; it will also automatically calculate the draught risk.

The Testo 440 Air Velocity and IAQ Tester is a reliable, easy-to-use, versatile instrument suitable for measuring air velocity and IAQ parameters. It can be used to adjust air conditioning and ventilation systems, monitor air quality, and conduct comfort level measurements. When used with the supplied hot wire probe (see below), the Testo 440 Air Velocity and IAQ Tester is ideal for measuring ventilation ducts of various sizes.
