Multifunction Instruments

The easy-to-use testo 480 is a high-precision digital temperature, humidity and air flow meter which allows you to measure, analyze and log all relevant ventilation and indoor air quality parameters with only one device.

The high-precision digital temperature, humidity and air flow meter is designed to provide independent experts, consultants, technical service providers and HVAC technicians in the field of ventilation and indoor air quality with an efficient means of carrying out all their measurements – i.e. norm-compliant setting and adjustment of airconditioning and ventilation systems in offices, residential and industrial buildings –using just one single device.

It is also designed to check quality parameters in production and processing quickly and reliably.

The intelligent concept behind the testo 480

The testo 480 has a built-in, high-precision difference pressure sensor for pitot static tube measurements and filter/clean room monitoring. There is also a wide range of high-quality optional sensors for carrying out the following measurements:

–  Air flow and volume flow(also fume cupboard measurements)
–  Temperature
–  Humidity
–  Pressure (difference and absolute pressure)
–  CO2
–  Illumination intensity
–  PMV/PPD
–  Heatradiation
–  Degreeofturbulence
–  WBGTIndex

The testo 480 digital temperature, humidity and air flow meter comes with a wide range of optional sensors and accessories – like the wireless testo quick printer for print outs on site –which allows you to customize your meter to suit your own pocket and meet your own needs.

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 with a huge 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 measurementsin 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, analyzedor logged. A specially developed protocol designer enables you to create protocols to suit your customers’ needs and the optional testoquick 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 Kthermocouple sensors)
