TN 850 |
|
|
|
TN850 is a high
precision thermocouple (S or R) calibrator over the temperature range 0°C to
1500°C. The internal automatic (and linearized)
Cold Junction Compensation function allows to get an
impressive tracking performance of 0.003°C/°C (between 0 and 50 °C). In addition
the self-adaptative linearization mechanism allows
to account for probe characteristics automatically during calibration by a
National Laboratory (with a residual non-linearity better than 0.01°C).
Measurements are provided at a 0.01°C resolution with following warranted key
performances:
- Long-term
drift < 0.01°C +20ppm of Rdg (per year) - Short-term
stability (jitter) < 0.2 digit ( = 0.002°C) -
Non-linearity residual < 0.01°C |
