Radon device
How Hanchen Home Radon Detector did in Health Canada's lab testing, its recall status and what its maker states, each with source and date.
Consumer electronic radon monitor
A consumer electronic radon monitor made by Hanchen. Health Canada's lab tested it in a published study. This page is the record: the lab result, the recall status and what the maker says, each with its source and date. Health Canada's advice is to choose an electronic monitor "that has passed the C-NRPP performance testing." Its brochure is linked in the sources below.
