About

ACIN VentiFlow

Features
Read full description

The VF-mk2 app from ACIN instruments receives measurement data from the ACIN VentiFlow-mk2 to your phone or tablet via Bluetooth®. The readings are recalculated for even greater accuracy. Based on the ventilation plan, the design requirements and other data, a template can be created with all rooms and valves. This template can be easily duplicated. You can then quickly measure and report, with the app helping you to balance a ventilation system. The data can be saved (CSV file) and sent from the app via an e-mail program or a messenger service. The app is partly free, the project module requires a key that can be requested from ACIN instruments (info@acin.nl) https://acin.nl
