Response time
with stainless steel mesh sensor cover (F5200B) and bronze sensor cover
(F0000 - selectable option), air flow approximately 1 m/s:

step 20 °C (36 °F) )
T3319P, T3419P t90 < 16 min (temperature step 20 °C (36 °F) )
relative humidity:
t90 < 30 s (humidity step 65 %RH, constant temperature)

This value depends on the barometric pressure. If device doesn’t support pressure measurement, then
constant value stored inside device memory is used. Default value preset by manufacturer is 1013hPa and
can be changed by user’s software.
3
This maximum is reached under conditions about 70°C/100%RH or 80°C/70%RH
4
There is possible to change response time. For more details see file “Description of calibration and
adjustment procedure.pdf”, which is installed together with Users software.
