Product overview

APPA S2 is a multimeter for measurements for HVAC sanitary engineering (air conditioning, building ventilation). The device has a backlit LCD display with a maximum indication of 6000. The APPA S2 allows you to connect to the APPA Connect application via Bluetooth. The app is supported on both Android and IOS operating systems.

See the Related Products tab for available cases for the measuring device.

The APPA Connect app allows you to read the results on your phone's screen. Graphs of signal waveforms over time are available. Using the app, the user can keep data logs and record the readings of the measured quantities.
