0-10V PAR Sensor IP67 Waterproof Photosynthetic Radiation Transmitter DC24V

Cosine corrector ensures standard cosine response, with sensitivity proportional to the cosine of incident angle, minimizing angular measurement error across all light source positions.

Accuracy specified at a defined 1000 umol/m2/s, 550nm, 60% RH, and 25 degrees C reference, providing a traceable and comparable performance benchmark across different sensor brands.

Sub-0.1-second response captures rapid changes in photosynthetic light intensity caused by cloud cover, shading, or artificial grow light switching in real time without lag.

Linearity error held within plus or minus 1%, ensuring output signal scales proportionally with actual PAR flux across the complete measurement range without correction tables.

Year-over-year drift controlled within plus or minus 2%, maintaining calibration integrity across multiple growing seasons without requiring annual recalibration or replacement of sensing elements.

Housing surface undergoes special treatment that reduces dust adsorption and rain adhesion, keeping the optical path clear and minimizing measurement errors from particulate buildup.

Full aluminum alloy construction with IP67 protection withstands 30 minutes of submersion at 1 meter depth, enabling installation in rain, irrigation, and high-humidity environments.

RS485 variant draws only 0.06W, the lowest in Renke's radiation sensor lineup, supporting solar or battery-powered deployment in remote agricultural and meteorological monitoring sites.

Integrated bubble level and hand-adjustable knob enable accurate leveling on-site without additional leveling tools, ensuring the cosine corrector faces true vertical for accurate measurement.

Each unit is fully calibrated before shipment and requires no customer recalibration, eliminating the need for reference light sources or calibration equipment during field installation.
