Measures photosynthetically active radiation (PAR)
Quantum sensor
Dimensions 33x20mm
Supplied with 3m cable
Waterproof
Generates 0.2m per umol/m2/s
This quantum sensor is waterproof and measures only 33x20mm. The sensor generates 0.2mV per umol/m2/s. It is supplied with 3m of cable. It can be used with data acquisition systems or simply connected to a multimeter capable of measuring mV. The measured voltage is then converted to PAR/PPF range simply by multiplying the value by 5. This is a cost effective solution for your PAR monitoring and measurement.
In order to keep lighting at constant levels optimal for coral growth it is possible to measure and monitor levels of photosynthetically active radiation (PAR) as well as LUX. Metal halide lamps alongside fluorescent lamps will loose some intensity over a period of time. By measuring PAR it is possible to adjust lighting levels accordingly:
Change MH and fluorescent lamps only when it is needed and at the right time
Adjust the distance of the lighting fixture from the aquarium. The distance of the lighting fixture from the aquarium can be increased when the lamps are new and later lowered to maintain constant lighting levels
Position corals requiring more intensive light at a correct depth
