The multi-parameter WET Sensor by Cambridge based Delta-T Devices Ltd was used by Chinese astronauts aboard the Tiangong 2 space laboratory.
Two Chinese astronauts, Jing Haipeng and Chen Dong, spent 30 days aboard the Tiangong 2 space lab carrying out numerous experiments, one of which was to cultivate lettuce plants within the weightless atmosphere. The WET Sensor played a key role in the space lab experiment, providing frequent accurate data on substrate moisture, temperature and pore water conductivity. This information allowed the astronauts to precisely assess growing conditions (including nutrient values) on a regular basis. The experiment was a success
