SQ-618-SS Modbus Digital Output 380-760 nm ePAR Sensor

$515.00

The SQ-618-SS ePAR sensor outputs a digital signal using Modbus RTU protocol over RS-232 or RS-485. The sensor features a rugged, aluminum housing that is fully-submersible and built to withstand harsh conditions, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. The sensor cable includes an IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement from permanent installations for maintenance and calibration. Typical applications of ePAR sensors include total ePAR intensity measurements over plant canopies in all growing environments, monitor and adjust grow lights, research plant morphogenic activity, and photobiology studies. 

The analog version of this sensor (SQ-610) comes with the inline cable connector placed 30 cm from the sensor head for either standard use as a long-cable pigtail sensor, or for use with our microCache Bluetooth Micro Logger by unscrewing the connector, discarding the long section of cable and then screwing the sensor to the mating connector on the microCache.

How is the SQ-618 different from previous Apogee quantum sensors?

The SQ-618 is an extended photosynthetically active radiation (ePAR) sensor with a spectral range of 380 to 760 nm ± 5 nm, which can be seen in the graph below. 
SQ-610 Spectral Response
Where is the SQ-610 used?

The SQ-610 is used for measuring the newest generation of LED grow lights with wavelengths outside the traditional 400-700 nm PAR range. Research has shown the value of adding UV and far-red LEDs to fixtures to achieve various disease control and photomorphogenic effects. The extended range filter of the SQ-610 allows it to measure photons from UV and Far-red.
