11 Technical data
11.1 Dimensions and weight
Height: 145 mm
Width: 185 mm
Depth: 41 mm
Weight of instrument including sensor: 1kg
11.2 Electrical data
11.3 Noise level
< 65 dBA, at a distance of 1 m
11.4 Exhaled NO - performance data
The instrument is verified to fulfill the specified performance under a
temperature range of +10 to +35 °C, relative humidity range of 20-80% and
pressure range of 700-1060 hPa.
Measurement range:
FeNO: 5 to 300 ppb
Lowest Detection Limit: 5 ppb
Determination by analysing gas concentrations around and below the
detection limit. 5 ppb was the lowest detectable level.
11.5 Linearity
Squared correlation coefficient r
2
≥ 0.998, slope 0.95 -1.05,intercept ±3 ppb.
11.6 Precision
< 3ppb of measured value for values < 30 ppb, < 10% of measured value for
values ≥
30 ppb. Expressed as one standard deviation for replicate
measurements with the same instrument, using a certified gas concentration
of Nitric Oxide reference standard.
11.7 Accuracy
±5 ppb for measured values < 50ppb or 10% of measured value for values
≥ 50 ppb. Expressed as the upper 95% confidence limit, based on absolute
mean of differences from certified gas concentration of Nitric Oxide.
11.8 Method comparison
< 10 ppb for values ≤ 50 ppb, < 20% for values > 50 ppb. Expressed as the
difference between a NIOX MINO® FeNO value and the corresponding FeNO
value measured with NIOX VERO® instrument from Circassia.
11.9 Inhalation parameters
Inhale to TLC (Total Lung Capacity) before start of exhalation. Inhalation in
instrument is triggered by a pressure of -3 cm H
