Photo-Radiometer Thermometer Data Logger With Working Temperature -5 To+50 Degree C, DO9721 performs photometric, radiometric, PAR and temperature measurements and it has two inputs has beendesigned for measuring illuminance, irradiance, luminance and temperature.The instrument has two inputs, A and B, and automatically detects the sensors,whether illuminance, irradiance, luminance or temperature and can provide aview of the difference between the two inputs. As the probes are interchangeable,it is possible to choose the most suitable combination for all applicationswithout having to recalibrate the instrument. The DO 9721 can take illuminancemeasurements in lux and in fcd (foot-candle), irradiance measurements in W/m2, in W/cm2 and in molm-2s-1,With the data logger function the instrument stores up to 30,000 readings withselectable sampling interval from 1 second to 12 hours
