TN 500

TN500 proposes at very low cost impressive performances: - resolution of 0.01°C over the entire range -180 to +650°C - residual non-linearity better than 0.005°C (the self-adaptative linearization mechanism allows to account for probe characteristics automatically during calibration by a National Laboratory) - Long-term drift < 0.01°C +0.01% of Rdg (per year) - Short-term stability (jitter) < 0.5 digit ( = 0.005°C) - Temperature coefficient < 5 ppm/°C (max.)
