Page 5: Introduction
Apogee Instruments SE series photometric sensors consist of a cast acrylic diffuser, optical filter, photodiode, and signal processing circuitry mounted in an anodized aluminum housing, and a cable to connect the sensor to a measurement device. -
Page 6: Sensor Models
SENSOR MODELS This manual covers the unamplified model SE-100 (in bold below). Additional models are covered in their respective manuals. Model Signal Measurement Range SE-100 Self-powered 0-150000 lux SE-202 0-2.5 V 0-5000 lux SE-205 0-5 V 0-5000 lux SE-212 0-2.5 V... -
Page 7: Specifications
Apogee SE series photometric sensors are calibrated through side-by-side comparison to the mean of four transfer standard SE-100 photometric sensors under a reference lamp. The transfer standard photometric sensors are calibrated through side-by-side comparison to the mean of at least two reference photometric sensors under a reference lamp. - Page 8 Spectral Response The mean relative spectral response of four SE-100 photometric radiometers (green) compared to CIE- 1931 curve (dotted).
- Page 9 Apogee SE series photometric sensors is approximately ± 2 % and ± 5 % at solar zenith angles of 45° and 75°, respectively. Cosine response measurements were made by direct side-by- side comparison to the mean of four reference SE-100 photometric sensors.

Page 10: Deployment And Installation
AL-100 Leveling Plate is recommended to level the sensor when used on a flat surface or being mounted to surfaces such as wood. To facilitate mounting on a mast or pipe, the Apogee Instruments model AL-120 Solar Mounting Bracket with Leveling Plate is recommended. -
Page 11: Cable Connectors
CABLE CONNECTORS Apogee sensors offer cable connectors to simplify the process of removing sensors from weather stations for calibration (the entire cable does not have to be removed from the station and shipped with the sensor). The ruggedized M8 connectors are rated IP68, made of corrosion-resistant marine-grade stainless-steel, and designed for extended use in harsh environmental conditions. -

3. Salt deposit accumulation from evaporation of sea spray or sprinkler irrigation water. Apogee Instruments upward-looking sensors have a domed diffuser and housing for improved self-cleaning from rainfall but active cleaning may be necessary. Dust or organic deposits are best removed using water, or window cleaner, and a soft cloth or cotton swab. -
Page 16: Troubleshooting And Customer Support
Compatible Measurement Devices (Dataloggers/Controllers/Meters) SE-100 series photometric sensors are calibrated with a standard calibration factor of 1000 lux per mV, yielding a sensitivity of 0.001 mV per lux. Thus, a compatible measurement device (e.g., datalogger or controller) should have resolution of at least 0.001 mV in order to provide illuminance resolution of 1 lux. -
