JRI's LoRa SPY T3 measures and records temperature via an external cable sensor. It is available with a length of 50 cm or 6 metres. The measuring range of -200°C to 0°C makes this sensor suitable for measuring -80°C freezers and special nitrogen baths (cryotank or cryogenic tank). The logger is equipped with internal display and 3 alarm LEDs (green, blue, red). The LoRa SPY operates +/- 2 years on one lithium battery and has a memory for 10,000 measurement points. Optionally available with a COFRAC (primary ISO 17025 certificate) or traceable calibration.
