SWA 10 is an air differential pressure probe that is used on Swema 3000 instead of the inbuilt or sensor in Swema 3000md or mdH+.
Swema 3000 can calculate air velocity and air flow. SWA 10 is also used with a leakage tester together with Swema 3000md or 3000mdH+ and
SWA 10 has an inbuilt valve that zero checks the pressure. SWA 10 has two holders attached so it can be fitted on any Swema 3000.
