Convenient
data analysis

By using Comfort software, the
information from testo 545 can be
downloaded and a location list can be
saved. Separately saved light intensity
values can be connected to form a curve
using Professional software. This “light
profile” provides information on the
uniformity of the lighting on i.e. repro
tables, paintings, in halls etc..

Mean calculation Location management

Two mean calculation functions, timed and multi-point, are
available to the user. The mean values can be saved in the
memory and printed.

A special feature of testo 545 is its location management
function. Up to 99 readings can be allocated to the locations
which ensures clear identification and documentation.

Lux

Adapting to the human eye

Our eyes are much more sensitive to
yellow/green light than to blue and red
light. A special optical filter in the
testo 545 allows the instrument to
reconstruct the response of the human
eye. A special photo diode cell converts
this light into an electronic signal
which is then displayed.

Approximately 80 % of all sensations
are experienced by the eye. Light is
required for this purpose. Accurately
measuring this light is easy and
convenient using the testo 545.

Light meter/logger with location management and mean calculation

To insure proper lighting, the testo
545 Light Meter accurately measures

and quickly stores light values.

Mean calculation

The mean value can be calculated at the
touch of a button from measured values
(max. 99). This is particularly helpful
when, for example, the mean light inten­sity on a table surface is to be measured.

Data/Location management

Data and locations can be entered and
saved on-site with the testo 545. Using
Comfort software (accessory), measure­ments can be downloaded and analyzed
easily and conveniently.
