The pro set for cleanroom technology/ordering suggestion testo 400
Defined process ambient
conditions must be assured for the
qualification and validation of the
high quality standards of
production units in
clean rooms.Air exchange and the resulting airflow are linked directly to air
temperature and air moisture.
Specified air flows produce defined
positive pressures which prevent
the ingress of impurities from
outside.Testo’s measurement technologyhas proven to be ideal for testing
process ambient conditions.With the testo 400 referencemeasuring instrument, you have the
possibility of connecting 2 probes
simultaneously. The measuring
instrument can then be used to
monitor measurements on-site or
for long-term measurements thanks
to the integrated readings memory
with capacity for 500,000 data. Accurate a air m moisture m measurement Ingoing air/VAC->clean room The task at hand is to monitorexactly the fluctuations in air
moisture with an accuracy of up to
±1%RH. testo 400 sets new
standards in terms of accuracy and
long-term stability. The worldwide
inter-laboratory test with the
patented
humidity sensor in
leading, international institutes
confirm the stated values.

Measurement o of i ideal a air s supply testo 400, with its thermal, vane
and
pitot tube measurements, has
all the technology available to
measure air flow. A calibration
accuracy from 0.5% of the reading
is assured thanks to the first PTB
accredited DKD laboratory for flow. Isolator Class AOutgoing airIngoing air/VAC ->insulator

exhaust fans and for
measuring laminar flow is new.
Owing to its optimum flow impact
characteristics with a direction-
independent measurement within a
possible twist angle (20°) and an
accuracy of ±(0.02 m/s +5 % of
reading), the probe is optimally
designed for the measurement of
laminar flow. testo 400 display during thecalibration of a stationary

The testo 100 Pa probe with an
