. It was in a box of fish stuff I got with my tank years ago. I just stumbled across it today while cleaning and tossing stuff out.

That looks like a lux meter, not a PAR meter.  If it doesn't specifically say it's water proof it's probably not.   It will work fine for measuring relative light levels between different locations and different tanks.  Both lux and PAR measuring standards measure blue and red parts of the spectrum.  The biggest difference between lux and PAR is lux also includes the green and yellow spectrum.

I sealed the wet and up with silicon to make it waterproof.  It comes in handy from time to time when trying to figure out where the bright/not bright spots are in the tank.
