There is no problem with snow accumulating about the sensor as it’s mounted several feet off the ground and pointed downward and the Fluke 411D/414D or 419D are mounted in a waterproof enclosure with only about a 1 inch opening for the laser and led pointer to pass thru. I’ll see if I can get a picture shrunk down enough to post. If not I’ll PM you one.
Ops Laser sensor is the one on the right.
