JRI's LoRa TEMP+T2/T2i data logger records and measures temperature thanks to a fixed external cable sensor. It is available with a length of 3 metres. Furthermore, the data logger is available as a standard version or special incubator version. The difference is in the temperature accuracy. The incubator version has an accuracy of +/- 0.2°C between 30°C and 50°C. The standard version +/- 0.3°C between -20°C and 30°C and +/- 0.5°C outside this measuring range. The LoRa TEMP+T2/T2i operates +/- 5 years on a single Lithium battery and has a memory for 10,000 measurement points. Optionally available with traceable calibration certificate.
