can this be submerged 24/7?

Yes it can be in the water 24/7.

Is this a combination pH electrode? Does it have a built-in reference electrode?

It's a BNC type pH electrode with built-in reference.

What input voltage range does this probe use?

They read charged hydrogen (h+) ions that get through a glass membrane. DC Milivolts

How do you calibrate this device? Do you have instruction manual I can take a look at?

It comes with a solution that I haven't used. To calibrate, I use some Atlas Scientific pre-mixed calibrated solutions. I do a 3-point calibration using pH solutions of 4.00, 10.00, and 7.00. I swap out sensors and calibrate once a week. My software has a scale factor and an offset to use the calibration. These are great pH sensors and better than the Atlas Scientific ones I used to use. However, you will have to average over many readings to get accuracy. I take 100 readings, keep the inner 60, and then average. It takes about 7 seconds to do all that.
