After correction, the impact of pressure changes is ≤ 0.01% measured value/1% pressure change or ≤ 0.002Vol. -% O ₂/1% pressure change (whichever is greater).

Caldos27 Thermal Conductivity Analyzer

Measurement object: Binary gas mixtures with different thermal conductivities, such as Ar in O ₂, H ₂ in Ar, CH ₄ in N ₂, etc.

Measurement range: There are different minimum ranges and ranges with zero suppression for different gas combinations, with a maximum range of 0-100Vol. -% or 0Vol. -% to saturation. The range can be freely adjusted within a given range, but should not be set within the ignition limit.

Performance indicators: Linear deviation ≤ 2% range; Repeatability ≤ 1% range; Zero drift ≤ 2%, minimum possible range/week; Sensitivity drift ≤ 0.5% minimum possible range/week; Output fluctuation (2 σ) ≤ 0.5% minimum range; Detection limit (4 σ) ≤ 1% minimum range.

Influencing factors: When the flow rate changes by 10l/h, it affects the range by ≤ 0.5%; The impact of environmental temperature changes is ≤ 1% range/10 ° C; the impact of air pressure changes on the minimum range is ≤ 0.25% range/10hPa, and the larger the range, the smaller the impact.
