Testo 160-T: Configure Wi-Fi Temperature Logging and Alerts

Quick answer: The testo 160 T monitors air temperature only using its integrated sensor, then transmits readings over Wi-Fi to the compatible Testo monitoring platform. Install it at the intended room location, configure the account and logging interval, verify time and alerts, and test data retrieval. To measure humidity, use a temperature-and-humidity model instead.

The 160 T sensor and its limits

Part 0572 2019 contains an integrated temperature sensor with a published measuring range of -30 to +50 °C (-22 to +122 °F). The product page states an accuracy of ±0.5 °C plus one digit and 0.1 °C resolution; these terms should not be confused with a guarantee that every room point has the same temperature. The logger is listed with IP65 housing protection, making placement and environmental suitability important rather than irrelevant.

The 160 T does not have a built-in RH channel. For humidity monitoring, choose the correct 160 TH or suitable 160 E plus an external sensor. For an external-probe alternative, see the guide to testo 160 E external probes.

Configure the logger and Wi-Fi connection

  1. Choose a sampling location representative of the storage space; identify any sensitive objects, door openings and nearby heat sources.
  2. Check the battery, device identification and compatible software/account. Confirm any Data Monitoring license needed for the installed monitoring service.
  3. Commission the device using the supported testo Smart App workflow and the site’s authorized Wi-Fi credentials.
  4. Set the logging and transfer intervals as allowed by the product, then confirm the clock, sensor reading and receiving dashboard.
  5. Assign alarm rules and recipients and perform a documented notification test; record what happens during a brief controlled connection interruption.

How often should it record?

The manufacturer lists a configurable measurement rate from 1 minute to 24 hours. Choose according to the rate at which meaningful room conditions can change and how quickly staff must respond. At 10-minute intervals there are 144 planned readings per day (24 × 60 ÷ 10); at 60-minute intervals there are 24. These calculations illustrate sampling density rather than the logger’s actual uptime. For a broader explanation of interval selection, see the guide to data-logging sampling intervals.

If the device stops transmitting

Check power, connectivity and account status, then distinguish missing updates in the cloud from missing measurements at the sensor. The manufacturer describes local measurement memory; consult the actual data history and manual before deciding how many observations are lost. An alarm about missing data should be recorded separately from a temperature-limit alarm. For guidance on memory and logger suitability, see the guide to temperature and humidity data logger selection.

Operational records and maintenance

Keep location, logger serial number, interval, software environment, calibration record and alert test results with the trend data. Avoid treating a cloud graph as an independently certified compliance record without site validation and access-control procedures.
