I cut another disc of 1/8 acrylic, lightly sanded one face to stop reflections, sandwitched a couple of filters between that and the existing top of the sensor, glueing it in place around the outer edge with Weldon #16. Now it reads 21 instead of 25, and the non-waterproof sensor reads 27. Both are close enough. When the sun comes out I will try a full sun reading again.
