Unit A57 BT is a Bluetooth datalogger that records over -40 °C – 85 °C and accepts an external temperature-humidity sensor or an external NTC temperature sensor in addition to its internal NTC temperature sensor. The external temperature-humidity sensor has ±0.3 °C temperature accuracy for 0 °C ≤ t ≤ 60 °C and a humidity range of 0 %RH – 100 %RH; humidity accuracy is ±2.5 %RH for 0 – 90 %RH and ±3.5 %RH for 90 – 100 %RH (25 °C). The internal NTC sensor is specified at ±0.4 °C for 0 °C ≤ t ≤ 60 °C and the external NTC sensor at ±0.5 °C for -20 °C ≤ t ≤ 40 °C. Storage capacity is 64000 sets with a 10 s – 24 h record interval; it provides an audible and visible alarm, the TempLink app, PC software and a USB Type-C port. It is used to record the temperature and humidity of a remote point in food processing, cold-chain transportation and storage. The housing is IP54 and an ER14505 battery gives about 2 years of operation; it weighs about 110 g with the battery. The external temperature-humidity sensor is included.
