Testo 445 multifunction meter
Brand: Testo
Reference: 5604450
Description
The Testo 445 multifunction is the ideal instrument to check air quality in controlled environments, facilitating the measurement of all the parameters that characterize ventilation and air conditioning systems, such as: temperature, volume flow and turbulence, in a single portable unit. air, CO2 concentration. It allows to check the good operation of the systems.
Details
Highlights
The Testo 445 multifunction is the portable measuring instrument for air conditioning preferred by maintenance technicians. By simultaneously measuring six parameters of environmental characteristics, the operator can assess the quality of the indoor air, facilitating the adjustment of the equipment and the programming of maintenance plans in the ventilation and air conditioning systems.
The connection with intelligent digital probes for the measurement of air velocity in supply or exhaust ducts, in addition to light intensity, temperature, volume flow, turbulence, absolute pressure, dew point, absolute or relative humidity, ambient CO, etc., facilitates monitoring for appropriate corrective actions.
In addition to wired data transmission, data transfer can be done wirelessly. The maximum storage capacity of 3,000 data. The values are transferable to a PC, for recording, analysis and graphic representation, using ComSoft Professional Software. Data can also be transferred to the Testo fast printer for instant documentation.
