Sensor resolution 0.1 Pa differential Pressure range 5–1000 kPa Channels 2 independent Cost per test Compressed air only Most parts that need a leak test do not need helium. They need a number, a repeatable verdict and a cost per test close to zero. This is the machine for that band of work: dry compressed air, differential measurement against a master part, two independent channels, and a controller that refuses to blame the part when the fixture is at fault. This machine is
