State-of-the-art technology for HVAC technicians and experts
The Testo 480 was designed to make your work more efficient and life easier. The high-quality, easy-to-use digital temperature, humidity and air flow meter can be used to measure all relevant ventilation and air conditioning parameters and carry out long-term measurements with only one device. What’s more it’s got a mammoth-size memory that can save up to 60 million measurements and a set of integrated programs that guide you through the following measurements step by step.
- VAC measurements in compliance with EN 12599
- Degree of turbulence measurements in compliance with EN 12599
- PMV/PPD measurement in compliance with ISO 7730
- WBGT measurement in compliance with ISO 7243
“Easy Climate” PC software
The “Easy Climate” software allows your readings to be transferred directly to a PC via a USB cable where they can then be presented, analyzed or logged. A specially developed protocol designer enables you to create protocols to suit your customers’ needs and the optional testo quick printer provides you with printouts on site.
Digital sensors and intelligent calibration concept
The optional testo digital sensors provide you with highly accurate results as there is no measurement inaccuracy from the meter. In addition, any deviations which are determined during calibration can be saved to the digital sensor. These deviations are compensated automatically giving you a zero error value. The intelligent sensors alert the user when the next calibration – which can be carried out by hand thereby ensuring that you always have your meter with you when you need it – is due.
The Testo 480 digital temperature, humidity and air flow meter has a built-in, high-precision difference pressure sensor with a measuring range from -100 to +100 hPa and connection possibilities for a further three optional digital and two temperature (type K thermocouple sensors).

Flow measurement in the ventilation duct according to EN 12599
Use testo 480 and the flow probes to carry out VAC grid measurements according to EN 12599 and to configure your system to make it energy-efficient. The measurement results can be presented to your customers on site in the VAC measurement protocol (link to pdf).
We have the ideal flow probe for your duct measurements:
- Probes for low, medium and high flow velocities
- Probe for turbulent flows
- Probes with non-rotatable, robust telescope. The scaling on the telescope ensures that the immersion depth is easy to read.
- Probe for ventilation ducts with small holes
- Air temperature and humidity can also be measured with the same probe as the flow velocity if required.
Selecting a suitable probe depends on the flow velocity in the ventilation duct. This can be broken down into three sub-ranges:
- Low flow velocities: thermal anemometers are suitable for this (order no. 0635 1543, 0635 1024, and 0635 1050)
- Medium flow velocities: the 16 mm vane anemometer provides the best results (order no. 0635 9542)
- High flow velocities: the pitot tube provides the best prerequisites (see following application)
Volumetric flow measurement at the air outlet
Every duct inlet and outlet should only contain the volumetric flow that according to calculations is a basic prerequisite to an efficient functional system.
The large vane anemometer with 100 mm diameter is ideal for measuring the volumetric flows at duct outlets (order no. 0635 9343), as it integrates the flow velocity over a larger area thereby determining disturbance from the air grille (loop method).
To measure the suction or blowing vents of air grilles and plate valves our volumetric flow rate funnel set is ideal (order no. 0563 4170) as is the large 100 mm vane anemometer (order no. 0635 9343) 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.
Differential pressure measurement on filters
Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air. These filters are to be inspected regularly to make sure they are still fully functional. To do this, the pressure is measured in front of and behind the filter. The result is the differential pressure. If it is too high, the filter is contaminated and needs changing.
Testo 480 uses the integral sensor to measure the differential pressure within the -100...+100 hPa range. The differential pressure measurement is temperature-compensated for exact readings. Magnets on the rear of the instrument allow hands-free work.
