testo 454 -The handy measuring instrument
Nearly all of the probes from the Testo range can be connected to the universal hand-held
instrument. The automatic probe recognition function facilitates quick control measure-
ments. In air conditioning technology several parameters can be quickly measured on
location e.g. temperature, humidity, velocity and pressure. The probe designs are fully
adapted to the respective applications.
testo 454 - The powerful data logger
All of the boundary conditions for an independent long-term measurement are program-
mable: start of measurement, end of measurement, location name and alarm outputs are
determined by selectable starting criteria. The six freely assignable channels and three
measuring programs make the data logger very versatile. There are various additional spe-
cial functions available for air conditioning and ventilation technology: averaging, volume
flow display, Pitot tube calculation etc.
testo 454 - Independent application
The rechargeable, environment friendly rechargeable battery makes the user independent
of the power supply. Power can also be supplied from a car battery.
testo 454 - User-friendly operation
The housing is ergonomic and ideal for practical operation and is made of robust ABS.
The large, illuminated display can be easily read and can display three different parame-
ters. The menu-driven user operation via the sealed keyboard makes the instrument easy
to use.
testo 454 - Configuring and data processing on the PC
If a PC and the Comfort software are connected you can take full advantage of the benefits
offered by the data logger. All of the settings in the data logger are prepared first in the PC
and are then loaded into the data logger. Only the measurement is started on the measur-
ing location. The processing of saved measured in the PC is just as uncomplicated as con-
figuring.
