便携式氧分析仪DF130E
Accuracy: (at constant conditions)
Standard Models: the greater of +/-3% Reading or 0.5% of Range
High Resolution Models: the greater of +/-3% of Reading or
0.02% of Range (except for the 0- 100 ppm range: the greate
+/-3% of reading or 50ppb; for the 0-50 ppm range: the
greater of +/-3% of reading or 10ppb)
微量氧气分析仪DF-130E系列
Oxygen Sensitivity:
Minimum Detectable Change 3 ppb (310E-H0050M model)
Low Detection Limit 3 ppb (310E-H0050M model)
Response Time
Responds instantaneously to O2 change. Typically less than
10 seconds to read 90% of a step change.
(Equilibrium time depends on specific conditions.)’
Range: Ranges are available
from 0.5ppm to 25%
Ambient Operating Temperature:
32º to 113ºF (0º to 45ºC)
Background Gas Compatibility

All inert and passive gases including N2, H2, CO, freons,
hydrocarbons, etc.
Sensor with Stab-EL Option:
Neutralizes trace contaminants including acids such as
CO2, H2S, Cl2, NOX, SOX, etc. (Consult Delta F for concentration limits)
