VICI Metronics Inc.
Model 230
The Model 230 is our basic calibration instrument, offering
all the standard features and configurations.
Description
VICI Metronics Dynacalibrators 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 230 to the most fully equipped Model 450, facilitate
accurate, reproducible, trouble-free calibrations time after
time.
Standard features include our proprietary constant temp-
erature system, a front-access permeation chamber large
enough to accomodate several permeation devices, and
a flexible flow metering system traceable to NIST standards.
Dynacalibrators can be supplied with internal pumping
systems, eliminating the cost and inconvenience of external
pumps, gas cylinders, regulators, and special plumbing.
Units with pumps can be equipped with accessory bypass
loops that provide for external modification of the carrier
and/or dilution gas streams.
Models
Model 340
A front panel MODE CONTROL switch selects ZERO,
SPAN, or REMOTE calibration modes. In the REMOTE
mode, the Model 340 can be programmed to deliver a
ZERO and a SPAN reference on command. In the ZERO
mode, scrubbed air is delivered to the STREAM OUTLET.
Model 450
Our most versatile calibration instrument incorporates a
second channel of dilution gas flow and a unique “through-
port” feature which eliminate the necessity of changing
plumbing connections between the sample manifold, the
analyzer, and the calibrator for each calibration. Also
included is a front panel MODE CONTROL switch to select
STANDBY, ZERO, SPAN 1 (low concentration gas), SPAN
2 (high concentration gas), and REMOTE. In the REMOTE
mode, the Model 450 can be externally programmed to
operate in all of its functional modes.
