Temperature Data Logger testo 184 T4 by testo — portable 4-channel temperature recorder

The testo 184 T4 is a portable 4-channel temperature data logger designed for continuous monitoring of temperature-sensitive goods and environments. It records temperature values from four separate channels and stores logged data for later download and analysis. The compact handheld instrument is suited for transport monitoring, storage checks, laboratory environments and process control where independent multi-channel temperature tracking is required. The device simplifies documentation of temperature history and supports quality control and compliance verification.

Advantages

The testo 184 T4 offers four independent temperature channels that enable simultaneous monitoring of multiple locations or products. Its portable design and intuitive interface make on-site deployment and data collection straightforward. The logger stores measurement series with timestamps for traceable records and is compatible with testo software for data evaluation and report generation. Long battery life and reliable sensor performance support continuous monitoring during transport and storage.

How to use

Install batteries and connect the required temperature probes to the four channels according to the probe type and connector specification. Configure the logging parameters such as sample interval and start/stop conditions using the device menus or the accompanying software before deployment. Place the logger and probes in the monitored locations or inside transport packaging, then start the recording. After the monitoring period, stop the logger and connect it to a PC or compatible reader to download the stored data for analysis and archiving.

Usage recommendations

For accurate multi-point temperature monitoring, position probes securely at representative measurement points and avoid direct contact with heat sources or condensation. Use appropriate probe types for the application (e.g., waterproof probes for refrigerated goods). Regularly verify battery status and perform periodic calibration checks to maintain measurement traceability and compliance.
