Environmental monitoring for server rooms and IT infrastructure.
Monitor temperature and humidity continuously to prevent overheating, detect failures early and protect the availability of critical IT systems.
Why environmental monitoring is essential in IT environments
Maintain safe operating temperatures
Continuous monitoring helps keep server inlet temperatures below 27 °C and prevents overheating or performance throttling.
Detect hidden hot spots early
Identify local temperature deviations caused by airflow issues or blocked floor vents before they affect system stability.
Protect hardware from humidity risks
Keep humidity within the recommended range of 40–60 % rF to prevent ESD risks and condensation on hardware.
Ensure early alerts and reliable documentation
Receive instant alerts when limits are exceeded and maintain documented conditions for audits and compliance.
Continuous monitoring.
Instant alerts. No surprises.
How automated monitoring protects IT infrastructure.

Continuously 24/7 monitoring
Data loggers continuously monitor temperature and humidity in server rooms and IT racks.
Central monitoring and secure data storage
All measurement data is stored in the testo Smart Connect Cloud for centralized monitoring and documentation. (Note: Testo Data Monitoring license required.)
Monitor indoor conditions in real time
Access measurement data anytime via dashboard or the testo Smart App anytime. (Note: Testo Data Monitoring license required.)
Instant alerts and audit-ready reports
Receive alerts when limits are exceeded and generate reliable reports. (Note: Testo Data Monitoring license required.)
Protect critical IT systems
Easy-to-install loggers monitor temperature and humidity at critical points such as server inlets, outlets and racks to detect deviations early.
Instant alerts for uptime
Receive immediate alerts when limits are exceeded to prevent overheating and system downtime.
Secure monitoring for compliance
Maintain a continuous audit trail with traceable measurements for IT audits and standards such as ISO 27001.
Recommended online data loggers
for IT environment monitoring
Choose the right data logger depending on the number of monitoring points and the infrastructure of your server rooms or IT systems and combine them flexibly within the monitoring system.
For monitoring multiple points across server rooms
Online data loggers testo 164
The testo 164 loggers operate independently of the local network and connect to a central gateway that links the monitoring system to the network. Long battery life ensures reliable long-term operation.
Typical IT monitoring setup
testo 164 T – temperature monitoring
testo 164 H – temperature and humidity monitoring
testo 164 DC – door monitoring for server rooms
For monitoring critical points such as server racks or air inlets.
Online data logger testo 162
Monitor temperature and humidity. Integrated display for quick checks and WiFi connectivity for seamless data transmission.
Typical IT monitoring setup
testo 162 H1 – temperature and humidity monitoring
Central monitoring.
Reliable data. Full control.
All measurement data is centrally available in the cloud. Reliable alerts, secure storage, audit-ready reports and dashboard access via the testo Smart App give you full transparency and control. (Note: Testo Data Monitoring license required.)
