Table 2-2 Relative Thermal Conductivities of Typical Gas Components
(Specific Thermal Conductivities)
The relative values mentioned above were determined taking thermal conductivity of air as 0.566 ×
10 4 (cal/cm.sec.deg) = 100 (at 0°C).

Note 1. The indication errors mentioned above were obtained after adjusting the instrument by
using sample gas + air as a balancing material.
Note 2. How to read the table
(1) 1% of CO
2
causes an indication error of –0.125% on the H
2
indicator.
(2) 1% of CH
4
produces an indication deviation of –1.38% on the CO
2
indicator.
