DF-310E便攜式微量氧分析儀
Accuracy: (at constant conditions)
Accuracy: (at constant conditions)
Standard Models: the greater of 正負3% Reading or 0.5% of Range
High Resolution Models: the greater of 正負3% of Reading or
0.02% of Range (except for the 0- 100 ppm range: the greate
正負3% of reading or 50ppb; for the 0-50 ppm range: the
greater of 正負3% of reading or 10ppb)
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
Basic Sensor:
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)
Gas Sample Conditions
Sample Pressure
Operating Limits:
0.2 to 1.0 psig (1.03 to 1.08 BarA) - Standard
15-25 psig with welded sample inlet (orifice restricted)
2.0 psi vacuum to 0.2 psig (0.88 to 1.03 BarA) use pump
1.0 to 10 psig (1.08 to 1.7 BarA) use valve (optional) or
regulator (optional)
Above 10 psig (1.7 BarA) use regulator
Sensor overpressure damage limit: 10 psig (1.7 BarA)
Return Pressure: Atmospheric Vent (optimal)
Limits: +5 psig (1.36 BarA) to -5 psig (0.67 BarA)
Flow Rate: 1.0 to 2.0 SCFH (0.5 to 1.0 slpm)
Temperature (Gas Sample): 0o to 150o F (-17.8o to 66oC)
Moisture: No limits (avoid condensation)
Oil/Solvent Mist: <0.5 mg/ft3 (standard)
>0.5 mg/ft3 - use filter
Solid Particles: <2 mg/ft3 (standard)
>2 mg/ft3 - use filter
