The AF-R220 is optimum for testing discharge flow and airtightness. Additionally, the flow sensor is selectable from Laminar Flow or Mass Flow. It also features an easy-to-navigate configuration tool and a flow optimizer. On top of that, the AF-R220 also allows you transfer data between devices with the built-in data transfer tool. Language is also selectable from English to Japanese or Mandarin.
Measurement screen is selectable from 6 different screens.
The pneumatic circuit is cleaned at the end of every flow test.
After the flow test, the fill valve is opened to check there is flow.
The flow is compared with the value of Flow Master.
The measured flow is compared with the value of Flow Master in every test.
Samples the flows at Target Test Press (P1) to displays the optimized flow.
Samples the flows at two pressure points, Target Test Press (P1) and Off-Target Test Press (P2), to optimize the measured flow when the test pressure is off target.
Samples the flows at Target Test Press (P1) and other multiple pressure points within the allowable range to optimize the flow when the test pressure is off target.
Up to 5000 data are stored. USB can be used for data storing.
