CHAPTER 2 Checks and Preparation
1. Combined illumination / ultraviolet sensor and temperature and humidity sensor measurement
Composite measurement can be done by using the illumination / ultraviolet sensor (GS-LXUV) and the
temperature and humidity sensor (GS-TH) (each sold separately).
It is not possible to be used by connecting two same sensors.
