Features an improved detector that provides excellent measurements under all light sources, including LEDs, right out of the box. The full-spectrum quantum sensor has a spectral range of 389 to 692 nm ± 5 nm seen in graph to the right. The sensor is available attached to a hand-held meter that provides a digital readout (MQ-510
), with USB communication and custom software (SQ-520
), and in multiple analog outputs to be used with a datalogger or voltmeter.
