NOTES:
1 Standard conditions are defined as 21.1 °C (70 °F) and 101.3 kPa (14.7 psia). Flow and volume accuracy are
applicable at these standard conditions. SLPM = standard liters per minute
2 For the High Flow Module, the temperature of the gas and the ambient air must be within ±10 °C (±18 °F) of
each other and the gas must be less than 30% relative humidity at 21.1 °C (70 °F).
3 For the Low Flow Module, the temperature of the gas and the ambient air must be within ±5 °C (±9 °F) of
each other and the gas must be less than 30% relative humidity at 21.1 °C (70 °F).
4 Flow and volume accuracies are stated at 21.1 °C (70 °F), 101.3 kPa (14.7 psia), and
<= 30% RH
• Add an additional ±0.075% of reading per 1 °C (1.8 °F) away from 21.1 °C (70 °F)
• Add an additional ±0.022% of reading per 1.03 kPa (0.15 psia) below 101.3 kPa (14.7 psia)
• Add an additional ±0.07% of reading per 1% relative humidity above 30% relative humidity
5 Must develop at least 7 cmH
