The easy to use testo 480 is a high precision digital temperature and humidity meter which allows you to measure, analyze, and log all relevant ventilation and air conditioning parameters with only one device.
This high precision digital temperature and humidity meter provides independent experts, consultants, technical service providers, and service technicians
in the field of ventilation and AC with an efficient means of carrying out all their measurements, i.e. norm-compliant setting and adjustment
of air conditioning and ventilation systems in offices, residential and industrial buildings - with only one device.
It is also designed to check quality parameters in production and processing quickly and reliably. The intelligent concept behind the testo 480 digital
temperature and humidity meter
The testo 480 has a built-in high precision pressure difference 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
- Heat radiation
- Degree of turbulence
- WBGT Index
State of the art technology for VAC technicians and experts
The testo 480 was designed to make your work more efficient, and your life easier. This high quality, easy to use digital temperature and humidity meter
can be used to measure all relevant ventilation and AC parameters, and to carry out long term measurements. The mammoth memory can save up to 60 million
readings, and a set of integrated programs 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
