testo 162 IAQ

Continuous Indoor Air Quality Monitoring for Safer, Healthier Spaces

The testo 162 IAQ is a Wi‑Fi indoor air quality data logger that automatically records CO₂, temperature and humidity. It enables continuous monitoring across offices, classrooms and public spaces, helping improve air quality, comfort and environmental control.

Improve Ventilation Control with CO₂ Monitoring

CO₂ measurement helps assess ventilation performance and detect poor air exchange. The testo 162 IAQ tracks levels over time, helping identify patterns and optimise ventilation in occupied spaces.

Reduce Manual Checks with Wireless Data Access

Automatically transmits data to a cloud or monitoring platform, reducing manual checks and enabling remote monitoring across multiple rooms or sites.

Support Health, Comfort and Productivity in Occupied Rooms

Continuous monitoring helps identify issues like poor ventilation, dry air or humidity changes, supporting better comfort, wellbeing and productivity.

Protect Sensitive Environments with Climate Documentation

Tracks climate conditions in museums, archives and labs, helping protect materials from damage caused by environmental changes.

Simplify Reporting for Facility and Quality Management

Provides clear, traceable data for reporting and audits. Supports workplace guidelines and quality processes with easy data export and analysis.

A Connected IAQ Logger for Modern Building Monitoring

The testo 162 IAQ combines CO₂ and climate monitoring with Wi‑Fi connectivity - helping improve air quality, optimise ventilation and support efficient facility management.
