Flow standards molbloc/molbox high accurancy flow calibration and measurement.
Gas Flow Standards - molbloc/molbox™ system for high accuracy, low gas flow calibration and measurement.
molbox™ Flow Terminals
molbox1+™
Flow Terminal
The new molbox1+ flow terminal from Fluke’s
DH Instruments Division represents a
significant update to the molbloc/molbox gas
flow calibration system. molbox1+ combined
with molbloc flow elements enables you to
achieve the lowest uncertainty available for
gas flow meter and controller calibrations.
A special configuration, molbox1+S, allows
you to use molbloc-S sonic nozzle flow
elements at higher pressures than were
previously possible, greatly extending
their usable flow range.

 

molbox1+ features at a glance

 

   • ± 0.125 % of reading uncertainty on mass
     flow measurements with molbloc-L and
     molbloc-S elements with premium
     calibrations

 

   • molbox1+S configuration gives extra
     rangeability with molbloc-S elements without
     requiring vacuum pumps

 

   • Now use any molbloc element for both
     high and low pressure applications in
     the same gas

 

   • 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.

molbox RFM™
Reference Flow Monitor
Choose molbox RFM if you do not need molbox to set and read analog MFCs
    • With microrange™ option, number of
      molblocs needed to cover your range is
      minimized
    • Flow measurement uncertainty of
      ± 0.5 % of reading
    • Microrange option to reduces measurement
      uncertainty under 10 % of molbloc full scale
    • Micromachined silicon, piezoresistive
      pressure transducers
    • Very compact presentation
    • Lower cost than molbox1

Warning - DHI has made sincere efforts to ensure the accuracy and quality of this tool. However, no warranty, expressed or implied is provided. DHI disclaims any responsibility or liability for any direct or indirect damage resulting from the use of this software product.
An Excel™ spreadsheet to help you to compare
the uncertainty (accuracy) of your Device Under Test
(DUT) and the various molbloc/molbox combinations
that DHI offers.
It determines the molbloc's uncertainty when used
with each type of molbox, and compares it to that of
the DUT.

 

The spreadsheet handles the "compound"
uncertainties such as %FS + %Reading, given
by many MFC manufacturers.

 

Range information for all three molbloc calibration
types and all of the molbox supported gases are
also provided. You can change the molbloc choice
at any time and the error and uncertainty ratio data
in the tables and on the charts is recalculated
and displayed.
