 VICI Metronics Dynacalibrators allow you to verify the accuracy of
analytical data from air pollution monitoring, industrial hygiene surveys, odor surveys,
and other instruments measuring gas concentration. All models enable calibrations
traceable to NIST standards for almost any gas analyzer, in the lab or in the field.
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.
Standard features on all our models, from the most basic Model 190 to the most
fully-equipped Model 500, facilitate accurate, reproducible, trouble-free calibrations
time after time.
Model 190
The Model 190 is our basic model, offering all the standard features and configurations -
solid state proportional temperature controller, digital readout for set point and chamber
temperature, stainless steel inlet and outlet, pyrex chamber, and cooling fan. Options
include a high pressure chamber for operation at 50 psi, an overflow outlet with activated
charcoal scrubber, and variable or fixed flow control.
 Model
230
With a flexible flow metering system to maintain a constant carrier flow through the
permeation chamber, the Model 230 allows the dilution flow to be varied over a wide range,
generating the spectrum of concentrations required for checking analyzer linearity. Like
all Dynacalibrators, its large permeation chamber is big enough to accomodate several
permeation devices, for higher output concentrations or multi-component mixtures.
Model 340
The Model 340 adds a front panel mode control switch to select among zero, span, or remote
calibration modes. In the zero mode, scrubbed air is delivered to the stream outlet. In
the remote mode, the Model 340 can be externally programmed to deliver a zero and a span
reference on command.
 Model
450
Ordinarily, plumbing connections between the sample manifold, the analyzer, and the
calibrator must be changed for each calibration. The Model 450’s unique
"through-port" feature eliminates this chore. The mode control switch selects
among standby, zero, span 1 (low concentration), span 2 (high concentration), and remote
modes. In the remote mode, the Model 450 can be externally programmed to operate in all of
its functional modes.
Model 500
This innovative design features two separate permeation chambers with independent
temperature control systems. The chambers can be used independently, or together to
combine concentrations of trace components. Separate solenoid valves allow the carrier
flows to be switched from the dilution flow to a vent port.
Portable dynacalibrator®
• Completely portable
• Pump powered by rechargeable battery
• Available temperature control from 20°C to 100°C
• Utilizes permeation devices - no bulky cylinders
 Standard features on
Models 115 and 120 include a glass permeation chamber with screw cap access, digital
readout for chamber temperature, a flowmeter and flow control valve, span and overflow
outlets, a 12 VDC internal pump, an activated charcoal scrubber, and a molded fiberglass
case. The Model 120 includes a solid state proportional temperature controller, with
digital readout for the set point and chamber temperature and a heater switch with LED
indicator.
