The Nano SPY TWIN is a 2-channel data logger from JRI records temperature thanks to an internal and external cable sensor. This cable sensor has a fixed length of 3 metres. This allows it to be used, for example, as a room temperature measurement and simultaneously for measuring the fridge/freezer temperature. Or it can be placed as a whole in a fridge and the cable sensor in the freezer compartment.

The internal sensor has an accuracy of +/- 0.4°C between -20°C and 40°C and +/- 0.5°C outside this measuring range. The cable sensor +/- 0.3°C between -20°C and 30°C and +/- 0.5°C outside this measurement range. The Nano SPY TWIN 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.
