Wouldn't depend on this for life safety
Thought it worked okay during the first flock we had it. Still maybe does ok the first poultry barn we wear it in, but after that it gets lower and further off from right in every barn after. And it always goes back to zero good when we go between the 6 barns. For a meter to do a good job consistently, it has to have a pump so it gets the same airflow all the time. Even when this one seems like it is working, it reads higher when walking then standing still.
