This unit has the following specifications:
Temperature Range: -55 to +200 degrees C/LC02 (Liquid Carbon Dioxide)
Rate of Temperature Change (Unloaded): 60 degrees C / min.
Stability: +/- 0.20 degrees C (including effects of line voltage, ambient temperature between 15 and 45 degrees C, and aging)
Uniformity:
+/- 0.3 degrees C from -40 to +80 degrees C
+/- 1.5 degrees C Max. from -65 to -40 degrees C and 80 to 200 degrees C (Measurements taken from within 1" [2.54 cm] from chamber walls)
This unit has the following Temperature Control functions:
Resistance of platinum resistance sensor converted to digital values
Internally stored mathematical polynomials convert digital values to temperature
Calibrated digitized temperature compared to user-set temperature
Four-point calibration provides greater accuracy
