TECHNICAL DATA
Operating temperature range
+0 ... +50 ºC
NOTE
If the LiCl solution is used or stored in temperatures below
+18 ºC, its equilibrium humidity changes permanently.

*) The uncertainty given in Greenspan's calibration table (on page 25) at the calibration
temperature, for example the accuracy of LiCl salt at +20 °C is ±(1.0 + 0.3) %RH
= ±1.3 %RH
