Highly accurate testo humidity sensor with long-term
stability (±2.0% RH)
Optional 2-line LCD display
P2A software for parameterization, adjustment and analysis,
saves time and costs in commissioning and maintenance
Optimum calibration concept thanks to adjustment of the
entire signal chain (1-point, 2-point and analog adjustment)
Adjustment without dismantling the transmitter

passive humidity and temperature analog output
Humidity transmitter
testo 6621
A broad variety of the testo 6621 transmitter is available.
Depending on the application in a room or in a duct,
the corresponding designs can be selected. A display
is available as an option. You can choose between
the housing colours grey and white. The testo 6621 is
persuasive in technical terms thanks to the patented
humidity sensors that guarantee the highest accuracy. The
sensors and the analog outputs can be adjusted, analyzed
and parameterized via the external interface using the P2A
software.
The testo 6621 is a high-performance transmitter for a low
price. It meets the increasing requirements in automated
building services in terms of accuracy, reliability and safety
and thereby saves energy costs.

* The determination of the measurement uncertainty takes place
according to GUM (Guide to the Expression of Uncertainty in
Measurement):
In the determination, the accuracy of the measuring instrument
(hysteresis, linearity, reproduceability), the uncertainty contribution of
the test site as well as the uncertainty of the adjustment site/works
calibration are taken into account. For this purpose, k=2 of the extension
factor, the usual value in measurement technology, is used as a basis,
corresponding to a trust level of 95%.
