Question

An electronic leak detector can detect leak rates of about ____ per year:

Answer 1

An electronic leak detector can detect leak rates of about 1-2 ppm per year.

Step-by-step explanation:

An electronic leak detector can detect leak rates of about 1-2 ppm per year.

This means that the detector is capable of detecting leaks that result in a concentration of 1 to 2 parts per million (ppm) of the substance being leaked in the surrounding air within a year.

For example, if a gas is leaking at a rate that would increase its concentration in the air from 0 ppm to 2 ppm over the course of a year, the electronic leak detector would be able to detect it.
