Identical Test Conditions as Above, Except in Heating Mode. TEC’s Higher Heating Mode Efficiency

Results in Higher Thermal Gain. 0.002

°C Peak-to-Peak Variation Is 4x Stability Improvement.

Baseline Tilt, Just Detectable, Shows Similar 4x Improvement vs Above

Long-Term Cooling Mode Stability Measured in Environment that Steps 20 Degrees Above Ambient

Every Hour. Data Shows Resulting 0.008

°C Peak-to-Peak Variation, Indicating Thermal Gain of

2500. 0.0025
