  "textContent": "A leak testing system includes a first test station, a second test station, a conveyor, and a controller. The first test station includes a first infrared camera equipped with a first optical CO2 lens filter, a first backdrop including a first heated surface and a first mirror, a first vacuum source, and a first CO2 gas delivery system. The second test station includes a second infrared camera equipped with a second optical CO2 lens filter, a second backdrop including a second heated surface and a second mirror, a second vacuum source, and a second CO2 gas delivery system. The first infrared camera is disposed to monitor a first field of view that includes the first backdrop. The second infrared camera is disposed to monitor a second field of view that includes the second backdrop. The controller includes a cell test procedure that is captured in algorithmic code.",
