With the Testo 480, you record, analylse and document all VAC-relevant parameters with only one instrument. The multi-function VAC measuring instrument stands out above all thanks to its accuracy and practice-oriented handling.

The high-precision digital temperature and humidity meter provides independent experts, consultants, technical service providers and service technicians in the field of ventilation and a/c 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.

The Testo 480 was designed to make your work more efficient and life easier. The high-quality, easy-to-use digital temperature and humidity meter can be used to measure all relevant ventilation and a/c parameters and 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.

The Testo 480 has a wide range of optional sensors and accessories (i.e. wireless testo turbo printer for print outs on site) which allow you to customize your meter to suit your budget and needs.
