Apogee Instruments introduceert de “Guardian” een meervoudige datalogger voor het nauwkeurig meten van belangrijke binnenmilieuparameters.

The Guardian Controlled Environment Agriculture (CEA) monitor is an elegant climate box for accurate, radiation-free measurements of key indoor environmental parameters.
Thanks to its flexible communication capabilities, the Guardian can be connected to climate computers and data loggers.
It features multiple integrated sensors for measuring PAR (SM-500) or ePAR (SM-600), air temperature, humidity, vapor pressure deficit and dew point, CO2 concentration, barometric pressure, daily light integral, and photoperiods.
