The VAC measuring instrument is equipped with intelligent digital probes with integrated memories. The probes inform the instrument as soon as the next calibration is due.
The calibration data are entered via the software and are then permanently stored in the probe. This compensates deviations automatically, producing a zero-error display.
The possibility of having the probes calibrated without the hand instrument ensures the uninterrupted use of the instrument. With the testo 480, professionals can detect negative environmental influences such as draughts, ensuring a climate of well-being, for example in open-plan offices, and sustainably reducing costs.
Measurement of all VAC-relevant parameters: flow velocity, temperature, humidity, pressure, light intensity, radiant heat, degree of turbulence, CO2, PMV/PPD and WBGT index
Integrated, guided measurement programs:
- VAC grid measurement according to EN 12599
- PMV/PPD measurement according to ISO 7730
- degree of turbulence measurment according to EN 13779
- WBGT-measurment according to ISO 7243 / DIN 33403
