Fluke MFC Switchbox™ for molbox1+ and MFC-CB™

MFC Switchbox supplies power and switches between up to five MFC or MFMs on one molbox1+ or MFC-CB channel.

The MFC switchbox is an accessory to the molbox1+ MFC option and MFC-CB mass flow control box. This accessory continuously powers up to five MFCs and/or MFMs (DUTs) and allows switching control between them on one molbox1 or MFC-CB channel.


Fluke MFC-CB Control Box

  • Set and read 0 to 5 V or 4 to 20 mA on two (2) channels simultaneously
  • Complete front panel local control and remote operation via RS-232 and IEEE-488 interfaces
  • Includes advanced features such as two (2) channel sum, difference and ratio
  • Displays in V, mA, % FS and flow units
  • Handles gas conversion (K) factors automatically
  • Switch each channel between five (5) channels using an MFC Switchbox™
  • Common look, feel and protocol with other molbloc/ molbox™ flow products
  • Compatible with COMPASS® for molbox software to set up automated molbloc/molbox based flow systems

Fluke molbloc-S Sonic Nozzle Calibration Device

  • Covers ranges up to 5,000 slm in N2 and air
  • Useable with molbox1+, or existing molbox1 and molbox RFM mass flow terminals and COMPASS software
  • Proven critical flow venturi (sonic) nozzle operating principle supported by gravimetric calibration
  • Minimal sensitivity to contamination
  • Measurement uncertainty:
    to ±0.125% of reading with molbox1+

  • Even more robust internal pneumatic design
  • Full suite of software automation products and hardware accessories to create a complete gas flow calibration system—including new COMPASS® for Flow calibration assistance software

Fluke molstic-L Mounting Systems

molstic molbloc mounting systems are available to assist you in realizing the full performance benefits of your molbloc/molbox™ system. molstics provide an engineered solution to the practical issues of mounting the molbloc, connecting a gas supply, regulating the pressure and connecting the device to be tested. Highest quality components are integrated into a compact assembly to assure optimum molbloc/molbox performance.


Fluke molstic-S Mounting System

The single channel molstic-S is designed to accommodate one molbloc-S element. The dual channel allows two molbloc-S elements to be simultaneously mounted, allowing use of two ranges without changing hardware during a test. In addition, the outlet of the two molbloc-S elements can be plumbed in parallel using the downstream tee assembly (P/N 401884) in order to obtain additional flow range capacity when using a two-channel molbox1+.
