TN-16N, TN-12N and TN-8N are multi-channel thermometers (respectively 16, 12 or 8 input channels) that offer high precision measurements to an accuracy of +/-0.01°C or better (when used with ITS-90 Pt100 sensor) with resolution at an impressive 0.01°C (over the entire range -180 to +650°C). Channel selection is performed either manually or automatically (scanning) or remotely. In addition its self-adaptative linearization mechanism allows to account automatically for each probe characteristics during calibration by a National Laboratory (with a residual non-linearity better than 0.002°C). Other key performances are: - Long-term
drift < 0.01°C +25ppm of Rdg (per year)
- Short-term
stability (jitter) < 0.2 digit ( = 0.002°C) - Temperature
coefficient < 2 ppm/°C (max.) |
