is supplied by Testo Calibration Certificates, regardless for which
parameter. Testo has a pacesetter function in the calibration sector.
How accurate are you?
Measuring instruments have to measure accurately, stably and reliably
over a period of years. These requirements are the basis of our
product philosophy. An indication of how serious we are is made clear
by the example of the development of our own, patented humidity
sensor. It took almost eight years before the sensor met our
requirements in terms of precision and long-term stability, response
time and temperature tolerance. It was then subjected to thorough
testing lasting more than a year before it was finally approved for use
by our customers. But we were still not satisfied. Over a period of five
years, inter-laboratory tests were undertaken involving nine renowned
international testing institutes, such as the PTB in Berlin (National
metrology institute), which documents the accuracy of the sensor
over this time in each of the testing institutes.
Air conditioning and ventilation engineering is a complicated and
multifaceted field – You know that as well as we do.
Highly diverse tasks such as planning, initial operation, approval and
service with different interfaces and high demands on energy
efficiency, hygiene and Indoor Air Quality all have to function in
harmony.
Technical requirements are high. Low energy consumption, high
operational safety, long-term availability, – at the same time, it must
be possible to regulate air conditioning and ventilation in the different
rooms individually and in real time.
Testo has the measurement engineering required. Complete solutions
for all parameters. Our many years of experience are reflected in our
practical and efficient measurement solutions.

It is impossible to find a comparable range of probes, optional probes
or conventional probes, for all the parameters required in air
