¹ 99 % of the sensors measure within these typical limits in equilibrium state at time of sale. For evaluation of the total measurement error
hysteresis and long-term drift has to be taken into account.
² Temperature accuracy is provided for a range 0 … +60 °C.
³ Humidity accuracy is provided at temperature +50 °C for a range 0 … 80 % RH.
⁴ Relative humidity drift value is provided at laboratory conditions: +23 °C and 30 % RH to 70 % RH. At temperatures higher than +50 °C over
a longer period of time, an increased long-term drift can occur.
⁵ Due to regulatory requirements 1 minute data transmission interval is not available in Russia.
⁶ Weight with alkaline AA Fujitsu LR6G07 Premium battery.
