Thermo Fisher Scientific Model 146 i Instruction Manual 1-7
Table 1–1 lists the specifications for the Model 146 i .
Table 1–1. Model 146 i Specifications
Gas Dilution
Accuracy of each Mass Flow Measurement
±
2% of reading or 1% of full-scale, whichever
is less (20 to 100% full-scale)
Linearity of Mass Flow Measurement 0.5% of full-scale
Repeatability of Mass Flow Measurement
±
2% of reading or 1% of full-scale, whichever
is less (20 to 100% full-scale)
Available Ranges
Zero Air 5, 10, 15, 20 slm
Span Gas 25, 50, 100, 200, 500 sccm
Dilution Ratio Depends upon choice of Mass Flow Controllers
Response time as measured at output of
manifold to 99% of final value Less than one minute for low flows. Faster for
high flow (for gas-phase titration mode
response time increases to 4 minutes). (Meets
or exceeds U.S. EPA Dynamic Parameters
specification requirements for gas-phase
titration.)
