## What is Aranet4 Display?

The Aranet4 Display is one of the tools from the Aranet family - meant for displaying the current air quality readings on larger screens. Use your Aranet4 for measuring CO2, temperature, relative humidity and atmospheric pressure, connect it to a tablet and display the actual readings for easier visibility. Alternatively use your smart device (phone or tablet) screen mirroring function to cast the value on a larger TV screen.

Ideal for restaurants, cafes, bars, supermarkets, gyms – anywhere where you want to show your visitors that your indoor spaces are safe from airborne infection risks. It is recommended to have 60 m3/h per person of air exchange to protect against potential disease containing aerosol buildup – this equates to approximately 800ppm CO2 concentration.

Aranet4 Display is the easiest way to ensure that everyone is aware of current risk levels, and can take action if ventilation needs to be increased.

### 4/5 — Aranet4 app needed to add a graph function

*2023-07-19*

This is a very good app, allowing one to read the Aranets4 meter’s carbon dioxide concentration in the air reading on your phone or iPod. It would improve the app’s utility if a graph option were added so one can see the CO2 concentration over time in the area where it is being measured.

### 5/5 — Excelent !

*2021-06-22, version 1.0*

Works as it should.
