Proof of temperature

. . . guarantee quality

Sensitive products require the right air conditions during production and
storage. The testo 400 includes all the functions needed to analyse air
with reference to temperature, humidity and air flow.

Highly accurate and efficient measurement of humidity and temperature
is required in many industrial processes to guarantee continuous quali­ty. Testo 650 calculates many moisture measurements like dewpoint
and absolute humidity

Guaranteeing quality usually involves maintaining a certain temperature.
This ranges in the food industry from frozen food temperatures to compo­nent temperatures in the electronics industry. Easy documentation and
filing of this measurement data is possible with testo 950.

for employees, employers and companies such as

HVAC and mechanical contractors.

If the volume flow is too low in HVAC systems, there will be insuffi­cient fresh air. If the volume flow is too high, this will cause ineffi­cient operation. The testo 400 easily calculates the CFM’s of venti­lation systems.

testo 650 is setting new standards in accuracy and long-term stability
with its worldwide inter-laboratory tests carried out in leading internatio­nal institutes enabling accurate monitoring of air humidity fluctuations of
± 1 %RH.

Extensive economic damage, depending on the application, could
be caused by uncontrolled moisture ingress. It is possible to measu­re and document readings over a long period of time using the testo

650.

testo 950 has a system accuracy of 0.09°F in the measurement range
from 32 to 200°F and a resolution of up to 0.001°F when used toget­her with precision probe 0614 0240. This high accuracy level makes
testo 950 ideal as a working standard.

Products and systems are subjected to different temperatures during
a production process. testo 950 has extensive monitoring options, for
example, a measurement program is started when a temperature
value is exceeded.

Measuring and application ranges of velocity probes

Thermal anemometers are best
suited for low speed velocities, vane
are utilizzed for the mid-speed
range, while pitot tubes achieve
maximum accuracy in high-speed
air velocity. The appropriate choice
of the right air velocity probe also

depends on the application
temperature. Thermal anemometers,
for example, have only a very limited
operating range. Testo designs and
manufacturers air velocity
instrumetns utilizing all three
measuring technologies. If the

measuring technology that best suits
your application needs is not on
display in this brochure, please call
Testo today to obtain additional
information.

The air velocity range betwen 0 to 20,000 fpm
can be divided into three measuring areas:

- Low-speed velocity 0 to 1000 fpm

- Mid-speed velocity 1000 to 10,000 fpm

- High-speed velocities over 10,000 fpm

The demand for a highly accurate
temperature measurement system came
mainly from sectors involved with quality
assurance, calibration services and

laboratories. This demand is accommodated
bya revolutionary highly accurate
immersion/penetration probe with a system
accuracy of up to 0.09°F.

The overall system measurement uncertainty
of temperature measurement in conventional
measuring instruments is made up oHhe
measurement uncertainty of both the

instrument and the probe. The instrument

measurement uncertaintyresuits mainly

irom the analog measurement technoloqy to

analyse the probe signal, analog-to-digltal
conversion, linearisationand resolution. The

probe measurement uncertainty is

determined by the precision oHhe

temperature sensor used.

The new, highly accurate measurement

system from Testo eliminates instrument

uncertainty and reduces probe measurement

uncertainty. Technologically, itis based on

the following components:

Intelligent probe

The reading is processed comPJetelr in the

probe from the analog sensor signa to the

digital reading. The overall instrument

measurement uncertainty therefore does not

apply.

Individual probe adjustment

Since each reading is processed completely

In the probe, each probe is adjusted

separately using highly

accurate fixed point cells.

Adjustment with fixed point cells
Kt

At the melting/solldification point, the fixed
point cells used keep the temperalure
constant over a jonger time period in the

0.0005 K range. The immersion/
penetration probe is adjusted in this phase.

Platinum sensor
A specially developed platinum wire,

integrated in a high-purily aluminium oxide
pipe, guarantees highest accuracy,

metrologicar stabilily as well as high
resistance even if exposed to high loads
such as acceleration and vibration.
Consequently, errors are eliminated thanks
to the individual parametering of the sensor
characteristic line in the probe.

The overall system uncertainly is reduced
considerably thanks to the elimination of the
instrument measurement uncertainly and the
reduced probe measurement uncertainly:

System accuracy at rated temperature 0122 oC'

-40 OC to 32 of ~.09 of + 0.05% of reading

There are even more system advantages in
addition to highly accurate temperature
measurement:

-System accuracy Independent of instrument
and socket: the highly accurate
immersion/penetration probe achieves full
accuracy regardless of the probe socket
used.

-Highly accurate differential temperature
measurements are thus possible with all
multi-channel measuring instruments.

The testo 400 with its VAC module is
currently the only measuring system
worldwide which can quickly and
objectively asses the functionality of a
ventilation system without requiring
any additional calculations.

Measurement stipulations are based on
internationally recognized standards;

AHSRAE 111, VDI 2080 (Germany), the
12599 Draft EN (Europe).

These are the first automated
measurement procedures which fulfill
the requirements of these standards.

The coordinates required for the grid
measurement are shown in the display.
