Introduction
Unpacking
Inspect shipments upon receipt and report shortages and incorrect or
damaged material to us immediately. Damaged shipments must remain
with the original packaging for freight company inspection.
The package should include the following:
• Dyncalibrator
® Model 150
• manual
• power cord
• forceps
• fittings kit
• tool to remove/secure the front panel and the chamber cap
Permeation devices, if ordered, will ship separately. The permeation device
shipping tubes, complete with the charcoal and desiccant packets, should
be kept for storing the devices when they are not in service. If a device will
not be used for at least a week and its total useful life is less than a year,
leave it packaged and place it in cold storage to prolong its useful lifetime.
General Description
The Dynacalibrator Model 150 is a constant temperature system designed
to generate precise ppm or ppb concentrations of chemical compounds in a
gas stream, using permeation devices as the trace gas source. It is used as
a reference for the calibration of instruments in the field of gas chromatog-
raphy, verifying the accuracy of analytical data generated from air pollution
monitoring, industrial hygiene surveys, odor survey programs, and tracer
studies, and in other instruments that measure gas concentrations.
A passivated glass-coated permeation chamber houses the permeation
device(s), with inert carrier gas sweeping the calibration gas/vapor from the
chamber. The temperature controller maintains the chamber temperature at
a set point with an accuracy of ±0.01°C, traceable to NIST standards. The
wide range of temperature settings (5°C above ambient to 110°C) allows
the end user to generate a wide range of volumetric concentrations for both
low and high vapor pressure chemical compounds. The desired volumetric
concentration is established or changed by simply varying the carrier flow.
The passivated glass coating of the stainless steel chamber assembly is
compatible with most chemicals, including sulfur compounds; however, it is
not compatible with hydrofluoric acid.
