Spectrum Technologies

Spectrum Technologies makes field instruments for agriculture and crop management. HenSistemas carries the WatchDog weather stations, which measure rainfall, temperature and, on some models, evapotranspiration, sending data over cellular or Sigfox networks to the SpecConnect cloud; the LightScout light sensors and meters (PAR, solar radiation and UV); and the FieldScout TDR soil moisture meters, alongside the WaterScout SM 100 sensor.

For assessing plants there is the SPAD 502 Plus chlorophyll meter and the FieldScout CM 1000, which calculates NDVI and flags stress before it becomes visible.
