Is this the right PAR sensor?

[Mark426]

I dont want to spend 375 on a PAR meter/sensor that I will use a couple of times but I know you can buy just the sensor and use a voltmeter to get the same results.

Question ....is the SQ-120: Electric Calibration Quantum Sensor the correct sensor?

Product Description
The SQ-120 is a self-powered quantum sensor that measures photosynthetically active radiation and is calibrated for use with electric lights. The sensor housing design features a fully potted, domed-shaped head making the sensor fully weatherproof and self-cleaning. Photosynthetically active radiation (PAR), or photosynthetic photon flux (PPF), is the wavelength range from 400 to 700 nanometers and is strongly correlated with plant growth. Gardeners, greenhouse managers, growth chamber users and salt-water aquarists measure PAR to insure optimal specimen health

Thanks,
Mark

Assuming that's from the Apogee site, yes... that's the correct one.

Just to confirm, yes, this is the correct sensor. Don't forget that To use the SQ-120 you will need a voltmeter that can read mV (milli-volts). Connect the positive lead of the voltmeter to the red wire of the SQ-120 and the negative lead of the voltmeter to the black wire of the SQ-120. Once you are reading the mV output from the sensor, simply multiply that reading by 5.0 to get your PAR reading.

Good luck. Let us know how it goes.
