Testo 184 T3 Transport Temperature Data Logger with Display (USB Data Logger) – Replaceable Battery, 500 Days, 40,000 Readings, −35…+70 °C, PDF Report (0572 1843)

Testo 184 T3 (product code 0572 1843), developed for monitoring the transport by road, rail and air of sensitive goods that require a cold chain, such as pharmaceuticals, food and electronics, is a USB temperature data logger with a display and a replaceable battery. With its internal NTC sensor it measures in the −35 … +70 °C range with ±0.5 °C accuracy and records up to 40,000 readings. It runs for up to 500 days on a user-replaceable CR2450 battery (15 min measuring interval, +25 °C); as a multi-use logger with unlimited service life, it is also suitable for in-warehouse logistics. No software installation is required: settings are made via the PDF configuration file inside the logger, and when it is plugged into a computer a PDF report containing the measurement data is generated automatically. It is EN 12830 and HACCP International certified.

Reusable Transport Temperature Logging with Display

The logger is delivered in deep sleep mode to save battery; pressing the START or STOP button switches it to standby mode. Recording starts by pressing the START button for about 3 seconds or automatically at the configured time, and Rec appears on the display; a start delay can be defined for button start. Recording ends by pressing the STOP button for 3 seconds or at the set time. To document the stages at which responsibility passes to another company during transport, up to 10 time stamps can be set by pressing the START button for 3 seconds.

Each press of the START button cycles the single-line LCD display through the current temperature, mean kinetic temperature (MKT), the highest and lowest recorded values and the remaining battery life in days; when the lower or upper limit is exceeded, the corresponding symbol appears on the display. At the destination, a glance at the LEDs is enough: if the Alarm LED is green there has been no limit violation, if it is red an alarm has occurred; the Battery LED turns red when the remaining battery life drops below 10 days; the Mode LED shows recording (green), ended (red) and standby (green and red) status.

When the logger is plugged into a computer's USB port, the configuration PDF inside it opens in Adobe Reader; settings such as the measuring interval (1 minute … 24 hours), start and stop criteria, and single alarm or cumulative alarm (triggered when the permitted total time is exceeded) are made and saved to the logger. The MKT calculation uses the standard activation energy of 83.144 kJ/mol as recommended by USP <1160>, which can be changed if necessary. The PDF report generated at the end of transport can be opened, printed or sent by e-mail; the configuration file, calibration protocol, user manual and PDF report are stored inside the logger. Thanks to the NFC interface, data can be transferred wirelessly to the Testo mobile printer (0572 0576). For fixed mounting, the Testo wall bracket (0554 1841) is available as an accessory.

Technician Tips

• Read out the data before changing the battery: when the battery is changed, an ongoing recording stops, the clock setting is reset and the logger switches to Reset (rSt) mode; stored data and PDF reports are retained. After changing the battery, reconfigure the logger with the configuration PDF.
• Insert the battery correctly: open the back cover by turning it counterclockwise with a metal coin; after removing the old battery, wait 10 seconds and insert the new battery with the positive pole visible. Use only new, fully charged batteries; the remaining capacity is not calculated correctly with a partially used battery. Testo has documented battery performance with EVE and Panasonic batteries.
• Use a fully charged battery in the cold: battery power decreases at low temperatures; a fully charged battery is recommended so that the logger does not reset. Below 0 °C the display updates more slowly (approx. 2 seconds at −10 °C, approx. 6 seconds at −20 °C); this does not affect measurement accuracy.
• Document handover points with time stamps: when responsibility passes to another company, set a time stamp by pressing the START button for 3 seconds; Min, Max, MKT and alarm values are reset with each stamp.
• Use software for long recordings: the graph in the PDF report is drawn with a maximum of 324 readings; to see all values in long recordings of up to 40,000 readings, Testo ComSoft software is recommended.
