TP-4501

Detector head for plant growth. Features: PAR, phototropism and photomorphogenesis actinic irradiance, illuminance, for use with X1 optometers, calibration certificate.

The TP-4501 is a unique detector head designed for use with the X1₁ or X1₂ hand-held optometer to measure on-site lighting conditions in greenhouses, plant growth studies, soil and seed science.

The compact detector houses four different detectors:

Yellow: PAR measures the photonsynthetically effective radiation in the 400 to 700 nm wavelength range actinic for plant growth
Blue: Measures the phototropism effective radiation within the 320 to 500 nm wavelength range actinic for directional plant growth
Red: Measures the photomorphogensis effective radiation within the 560 to 900 nm wavelength range actinic for plant growth formation
Green: Photometric V(λ) measures the illuminance which specifies the ambient lighting condition

Traceable Calibration

Calibration of the detector responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.
