Testo 440 Air Flow Combo Kit 1

Testo 440 Air Flow Combo Kit 1

Testo 440 Air Flow Combo Kit 1 is designed to measure air flow from ventilation outlets and ducts using the Testo 440 Multifunction Climate Meter as its main instrument. The kit also contains two useful air velocity probes in addition to a useful carry case.

The Testo 440 Multifunction Climate Meter is extremely versatile thanks to its compatibility with a wide range of both wireless and wired probes. It can measure parameters such as air temperature, humidity, air flow velocity, carbon dioxide, carbon monoxide and light intensity. The universal probe connection allows quick interchanging of probes and there is also an input for type K thermocouples. Evaluation of these parameters allows the meter to calculate further values such as dew point, wet bulb, volume flow and criteria for mould-friendly conditions.

The large internal memory on the Testo 440 has space for up to 7500 readings and these can be automatically recorded during inspections using the meter’s datalogging function. Files can then be downloaded in Excel format to a PC using the supplied USB cable. Operation is extremely easy thanks to the intuitive menu system and simple push-button interface whilst the vibrant colour display is capable of showing up to three readings simultaneously.

Testo 440 Air Flow Combo Kit 1 features a wireless 100mm vane probe that can measure air flow velocity from 0.3 to 35m/s with a high degree of accuracy and precision. It also enables the calculation of volume flow at outlets when used in conjunction with the Testo 440’s easily configured calculation feature. An internal temperature sensor measures air temperature from -20˚C to 70˚C and the universal Bluetooth handle is compatible with multiple probe heads.

The second probe contained within the kit is the Testo hot wire probe. This wired probe is slimmer than the vane probe - allowing easier insertion into ducts - and has a telescopic stem which can be extended up to 1m for penetrating further into shafts. It measures air flow velocity from 0 to 30m/s and air temperature from -20˚C to 70˚C.

Standard accessories like batteries, a calibration protocol and a carry case are also included and Testo Air Flow Combo Kit 1 constitutes a really useful option for assessing air flow at different points of HVAC systems.
