Apogee sensor.

Is it possible for reef angel to read/record a mV DC signal? From an external sensor such as an apogee-sq120

Can you really just measure mV from the sensor?

Not familiar with the apogee but I recently completed a DIY PAR reader and the output from that was mV. But why connect it to the reef angel?

Which sensor did you use?

This. It's 400 to 1100 but as I understand it everything over about 700 is filtered out when submerging it in the tank. I haven't calibrated it yet against another meter but it was interesting to see how much lower the light got just by lowering the sensor a few centimeters (or inches for you guys 
)

Per apogees instructions

Try plugging into the probe and see if it goes out of scale...
A ph meter is nothing more than a mV meter.
Same for the ORP, but the scale of the ORP is much higher.
