Light, UV and temperature transmitters

These transmitters are designed for users who need to monitor temperature, humidity and visible light or visible and ultra violet light.

GD72E with LS70

As all sensors are on leads, the combination is ideal for all environments and in particular display cases, so that only the light sensor and tip (top 10mm) of the RHT10E probe need be visible.

The LS50 ('Light puck') and LS70 modules utilise the museum and conservation industry preferred Elsec – Littlemore light / light and UV sensors. The GD72E transmitter interfaces with all sensors at digital level so that no system accuracy is lost. When used with Darca Heritage software both instantaneous and cumulative light and UV values can be provided

The LS50 light only module, LS70 light/UV module, and the RHT10E must be ordered separately.
