The
Gas blending system can mix and blend two or more gases
with each other at a predefined ratio. It can be used for
blending or to dilute gases to generate precise calibration
gas standards, production gas mixtures or to create gaseous
atmosphere. The gases can be mixed in a ratio of 1:1 upto
1: 1000.
The
system automatically dilutes high concentration certified
gas cylinder to a wide range of of concentrations from high
percentage to low parts per million.
The
system is operated by controls set at front panel. After
entering required concentration, the system automatically
mixes gases connected to the ports to generate required
mixture.
Gas
Mixing System
The
gas mixer precisely dilutes and blends high concentration
certified gas cylinders to generate precise gas calibration
standards, create gaseous atmospheres, or produce gas mixes
for analytical research and process gas mixture purpose.
The
mixer can produce complex mixes containing upto seven individual
gases in a balance gas. The mixer produces gases from a
percentage level to parts per million level for single or
multipoint calibration.
The
mixer consists of control instrumentation and mixing zone.
Commands are entered from front panel. Optional RS232 control
with computer controlled command mode is also available.
Product
Features
Reduced
cost of Gas Standards: Calibration gases is a costly
affair. The mixer reduces / stops costly expense of calibration
gases needed for calibration of instruments. Also reduced
inventory of gas cylinders due to broad range of dilution
ratios. It enhances profitability in process industries
due to eliminating costly process gas mixtures. The mixer
can be used for online gas mixing.
Wide
Dilution Ratio: Broad range of dilution ratios
( 1:1 upto 10000:1) allows user to significantly reduce
the number of gas cylinders needed to perform compliance
tests.
State
of the Art Software: Automatic calculation of dilution
and span gas flows based on the concentration commanded
by the user eliminates the need for manual computation allows
rapid transition from point to point and scale to scale.
The
mass flow controllers are calibrated to using a NIST traceable
primary standard.
