▪ Measurements
1. Steady state at ambient
Without thermal compound
OF/E-14 24.7°C TC 1 24.4°C
Tettex 24.7°C TC 2 24.4°C
2. Heating power: 17.6W
Steady state (~0.1°C per minute)
Without thermal compound
OF/E-14 67.9°C TC 1 69.5°C ΔT = -1.6°C
Tettex 68.1°C TC 2 69.6°C ΔT = -1.5°C
3. Heating power: 17.6W
Steady state (~0.1°C per minute)
With thermal compound
OF/E-14 69.4°C TC 1 70.0°C ΔT = -0.6°C
Tettex 70.2°C TC 2 70.3°C ΔT = -0.1°C
Thermal compound increases measurement accuracy! OF/E-14 (ΔT = -0.6°C) shows
slightly worse measurement results than the Tettex probe (ΔT = -0.1°C). But it is easier to handle:
