Agree. I've had cheap detectors fail to ping on a leak multiple times. I don't own this model but given Klein's target buyer and reputation I'd be inclined to trust that this is worth the price.

Can this be use to detect HVAC refrigerant leak? If not, typically nitrogen is used if the system is evacuated

Less mess if you are not sure of the leak location.

just know, the sensor has a life expectancy of up to 10 years. Like smoke and carbon monoxide detectors, they should be replaced near the end of their life.

Are there replacement sensors? Or does entire device get trashed after 10 years?

You will be scared to know how many micro leaks are going on at not just your house, but every house daily.

It's why there was that huge push to electric and induction. It has a measurable effect on greenhouse gases. So yes the electric causes more greenhouse gas but the removal of micro leaks make up for it

highly recommend you have one on hand. I bought one a while back and have used it a few times when I thought i smelled gas. Last year had a plumber change a gas line and turns out there was a legitimate leak i tracked down with this which was only occuring when the appliance downstream wasnt running (water heater).
