Low PPB to high PPM range
Temperature control to 100°C
Internal 4 LPM pump
Rechargeable 8 hour battery
VICI Metronics Dynacalibrators enable calibrations traceable
to NIST standards for almost any gas analyzer, in the lab
or in the field. They are ideal for verifying the accuracy of
analytical data from air pollution monitoring, industrial
hygiene surveys, odor survey programs, and other
instruments measuring gas concentration.
The design takes full advantage of all the conveniences
inherent in our Dynacal
®
permeation devices to generate
and deliver precise concentrations ranging from ppb to
high ppm for hundreds of different compounds. The portable
Model 120 features a glass or Teflon
®
permeation chamber
with screw cap access, solid state proportional temperature
controller with digital readout of set point and chamber
temperature, heater switch with LED indicator, flowmeter
and flow control valve, span and overflow outlets, 12 VDC
internal pump, activated charcoal scrubber, and molded
fiberglass case.
Description
Advantages Over Bottled Standards
Calibration devices from VICI
Metronics offer several
key advantages over
cylinder-supplied gas
calibration standards.
Economy is always a
major consideration;
customers who have
done the arithmetic, fac-
toring in the cost of cylinder
purchase, shipment , and
disposal, typically discover that the purchase of a
Dynacalibrator and a supply of permeation devices will
start to save them money in the second year of use.
Multicomponent mixtures can be easily generated with a
Dynacalibrator and the appropriate combination of
permeation devices. This technique also allows the removal
of a single component from a gas mixture by simply
removing the appropriate permeation device. Alternative
methods require expensive custom mixtures or a large
number of gas cylinders, which consume valuable lab
space as well.
Bottled standards can also have problems arising from
degradation of the standard within the cylinder, from
changes in the concentration levels as the cylinder pressure
changes, and from interaction of calibration components
and surfaces.
