    PAR sensor. Clip it to a digital multi-meter (or any device that measures millivolts). Red cable to positive, black to negative. Multiply the value of millivolts by 5 to calculate PAR. This device is waterproof. I just hand-positioned it in various locations in my aquascape to measure PAR. Alligator clips included. Calibrated for electric light, not sunlight.
    $100 shipped CONUS. Used it a handful of times. Stored with the cap on.
