CHAPTER 7

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.

Accuracy:

lithium chloride LiCl ±1.0 %RH +

Greenspan's

uncertainty*

magnesium chloride MgCl

±1.0 %RH +

Greenspan's

uncertainty*

natrium chloride NaCl ±1.4 %RH +

Greenspan's

uncertainty*

potassium sulphate K

±1.5 %RH +

Greenspan's

uncertainty*

*) 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
