High end gas flow calibration made simple

Fluke Calibration 5141, 5142 and 5144 molbox RFM gas flow calibrator kits feature molbox RFM and molbloc-L configurations optimized to cover a very wide workload combined with molstic-L and other interconnect hardware needed for a complete calibration system. Simply supply 90 psi of pure N2 or air to the system. An included regulator delivers a stable regulated flow to the molbloc. Downstream of the molbloc, an included metering valve allows you to regulate the mass flow value required for the DUT. It’s that simple; supply 90 psi gas upstream, tare the reading, and adjust the fine metering valve to deliver the desired mass flow rate with an accuracy of ± 0.5 % of reading. Fluke Calibration gas flow calibrator kits eliminate complication, but don’t compromise molbox/molbloc best in class performance.

  •  Flow ranges cover from 1 sccm to 50 slm
  • ± 0.5 % of reading total one-year accuracy
  • Measures mass and volume flow with user settable reference pressure and temperature conditions
  • Reference standard is upstream of the device under test, eliminating cross contamination and expensive damage to the flow elements
  • Integrated gas flow regulation and adjustment hardware
  • Expandable to over 5000 slm with additional molbloc flow elements and control hardware
  • Includes traceable calibration for operation in N2 and Air, with corrections for other gases
  • Gas supply and test adapters included for 1/4 in tube, 1/4 in NPT and 1/4 in BSP
  • Includes advanced functions such as totalize, average, hi/lo, deviation, on-board purge, leak test and tare, available from the front control panel or by RS-232 and IEEE-488 remote interfaces
