JRI's Nano SPY T3 measures and records temperature via an external cable sensor. It is available with a length of 50 cm or 3 metres. The measuring range of -200°C to 0°C makes this probe suitable for measuring -80°C freezers and special nitrogen baths (cryotank or cryogenic tank). The 0°C measurement range of 200°C makes this probe suitable for measuring ovens and/or furnaces, for example. 

The Nano SPY T3 features 3 alarm LEDs (green, blue, red) and internal magnet for mounting in the supplied mounting bracket or metal background. The Nano operates +/- 6 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.
