The new SQ-500 Full Spectrum quantum sensor and MQ-500 Meter feature an improved detector that provides excellent measurements under all light sources, including LEDs, right out of the box.
The improved spectral response of the SQ-500 increases the accuracy of LED measurements making it ideal for use with both natural and electric light sources.
This cosine-corrected sensor is designed to maintain its accuracy when radiation comes from low zeith angles. The sensors measure PPFD with a cosine response accurate within ± 5 % at 75 ° zenith angle.
The SQ-500 is available as an unamplified analog version with pigtail leads to be connected to a datalogger. Output is 0.01 mV per µmol m-2 s-1
Amplified models to be released mid-2016
The MQ-500 is available attached to a handheld meter
Head is potted-solid making it submerisble and suitable for use in all climate conditions.
To ensure accuracy each sensor iscarefully calibrated in controlled conditions and traceable to NIST reference standards.
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
The AL-100 is required for sensors on cable.
The AL-210 is used for mounting meters with integral sensor.
The AA-100 carry case is an optional accessory for protecting meters in the field
The AM-110 fits the AL-100 leveling base and can be mounted directly to a mast or pipe with an outer diameter of 33-53 mm.
The AM-001 is designed to fit to the back of a meter for mounting a sensor on cable.
The AM-310 is for placing sensors in difficult to access places, such as underwater or under canopy.
