Infrared surface RH scanner

[Guest guest]

Does anybody recall a small handheld infrared temperature scanner that puts a spot of colored light on the wall that changes color when it detects a wall temperature that corresponds to a specific surface RH ??I think it was a British woman demonstrating it on YouTube.
