SM-600: ePAR Guardian CEA Multi-Sensor Monitor
Datalogger with multiple integrated sensors to measure ePAR, air temperature, humidity, vapor pressure deficit and dewpoint, CO2 concentration, barometric pressure, and daily light integral and photoperiod. The SM-600 sensor measures extended photosynthetically active radiation (ePAR), which includes far-red photons, while the SM-500 does not.
