Quick answer: The testo 150 T1 is a Saveris 1 module with one integrated NTC temperature sensor. Install it at a representative location, add the required Saveris 1 communications interface, configure sampling and alarms in the system, and verify the resulting temperature trend. It does not measure relative humidity.
Identify the T1 and its measurement boundary
The module carries product number 0572 3350. Testo describes an integrated NTC sensor, a display and compatibility with separate WLAN, Ethernet or optional UltraRange communications modules within testo Saveris 1. No external temperature probe or humidity probe is implied by the integrated-sensor design. The value represents the local air environment at the logger, not the actual temperature inside a closed package or product. For the wider modular family, see the testo 150 configuration guide for module selection, Saveris setup and alarm testing.
Select the installation point
Position the logger where the monitoring objective can be met, based on a documented storage or environmental mapping exercise. Avoid door drafts, direct sunlight, heater discharge, metal heat sinks and proximity to frequently opened access points unless these are the conditions intentionally being monitored.
If product core temperature is the requirement, a module with a suitable external probe may be the better selection. Do not substitute a room-air trace for validated product-temperature monitoring. If multiple external temperature points are required, see the testo 150-TC4 setup guide for four-channel thermocouple logging and alarms.
Commission the 150 T1 within Saveris 1
- Record the instrument identifier and the calibration information supplied with the device.
- Mount the logger, install or check power, and attach the communication module specified for the infrastructure.
- Add the logger in the supported Saveris software/base environment; label its channel and confirm the live time and temperature.
- Set the measurement frequency and site-approved alarm thresholds; assign recipients and escalation responsibilities.
- Run a controlled alarm-notification test and confirm that recorded values continue or recover as the configuration specifies.
Worked example: sampling and monitoring gaps
Hypothetical: a cold-storage room is scheduled for one reading every 5 minutes. That represents 288 observations over 24 hours. A 15-minute network outage spans three nominal sampling intervals, but it does not prove that three readings are lost: examine the logger and software’s actual buffering and upload history before declaring a data gap. For a broader method for choosing intervals, see the guide to data-logging sampling intervals.
Avoid errors when interpreting alarms
| Finding | Check before concluding |
|---|---|
| One brief warm peak | Door opening, local airflow and sampling interval |
| No cloud update | Power and communication module, then local/logger status |
| Gradual offset from a reference | Location difference, stabilization, sensor uncertainty and calibration history |
| Missing humidity trend | T1 has no humidity channel; use a supported humidity-capable configuration |
Record verification and maintenance
Document instrument ID, location, reading interval, alarm test, communication path and any change of location. Follow the Saveris 1 manual for firmware and instrument maintenance, and maintain the required calibration program. DIN EN 12830 reference on the product page does not mean a complete site installation is automatically validated.
