About This Product
■Features
・Supports range up to 5,000slm with N2 and air
・Compass software can be used with molbox1+ terminal or existing molbox1 and molbox RFM mass flow terminals
Proven critical flow Venturi (sonic) nozzle operating principle supported by gravimetric calibration
・Very low sensitivity to contamination
・Measurement uncertainty: up to ±0.125% of reading (molbox1+), ±0.2% of reading (molbox1), ±0.5% of reading (molbox RFM)
・Air, N2, Ar, He and other calibrations are possible, supporting use under atmospheric conditions with humid air density correction
・Excellent rangeability of molbox1+S or other vacuum molbox models (10:1 turndown ratio)
Duplicate upstream absolute pressure measurements by using absolute pressure transducers from both molboxes, reducing uncertainty and increasing reliability
・Integrated gas temperature control and measurement
■Normally used pressure range
20-200 kPa (3-30 psia) absolute upstream pressure or 50-500 kPa (7-70 psia) absolute upstream pressure, 200-2,000 kPa (30-300 psia) only with molbox1+S
