Quantum Sensor PQS1 PAR
The Kipp&Zonen Quantum sensor PQS1 PAR provide the measurement of photosynthetic active radiation (light spectrum 400-700 nm). This is the part of the spectrum that plants use for photosynthesis. It is suitable for indoor or outdoor installation in agriculture and horticultural research centers.
PQS1’s sensitivity has been optimized to provide reliable and accurate measurements of solar radiation and artificial light sources (e.g sodium lamps). Optical design of the diffuser offers optimized cosine correction.
The mounting flange incorporates a bubble level and adjustment screws, for easy leveling. A threaded hole takes the accessory screw-in mounting rod for fitting to masts and poles. Two PQS1 sensors can easily be bolted back-to-back to make a simple PAR albedometer.
The standard cable length is 5 m, with an option of 15 m.
PQS1 is ideal for use with the METEON handheld display and portable data logger.
