Associated gas
influence
The effect of associated gases with a concentration of 100 Vol.-% as a shift of the
zero-point (ΔZero) in Vol.-% O

per 10 °C
• On sensitivity: ≤ 0.1 % of measured value per 10 °C
Ambient temperature in permissible range, thermostat temperature = 64 °C
Air pressure influence • At zero-point: no influence effect
• On sensitivity without pressure correction: ≤ 1 % of measured value per 1 % air
pressure change
• On sensitivity with pressure correction by means of internal pressure sensor
(option): ≤ 0.1 % of measured value per 1 % pressure change; for highly
suppressed measurement ranges ≤ 0.01 % of measured value per 1 % pressure
change or ≤ 0.002 Vol.-% O
