Response time with stainless steel mesh sensor cover (F5200) and bronze sensor cover (F0000 -selectable option), air flow approximately 1 m/s:temperature: t90 < 9 min (temperature step 20 °C) relativehumidity: t90 < 30 s (humidity step65 %RH, constant temperature)2
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 IE-SNC-T3413(7)-0811
