PQS1 PAR Quantum Sensor

PQS1 PAR Quantum sensor is developed for accurate measurement of PAR. It offers a response with an excellent match to the ideal PAR response. In addition the optical design of the diffuser offers optimized cosine correction. The instrument is designed for continuous outdoor or indoor installation. Perfect for studies of crop growth in green houses for example.

Both solar radiation and artificial light sources like for example high pressure sodium lamps are common sources of Photosynthetic Active Radiation.
PQS1’s sensitivity has been optimized to provide reliable and accurate measurements regardless of the PAR source. This is important for horticultural studies and plant physiology monitoring.

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, and fitted with the mounting rod, 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 data logger for field test use.
