VICI Dynacalibrator


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.

Dynacalibrator® Calibration Gas Generators

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 facilitate accurate, reproducible, trouble-free calibrations time after time.

  • Benefits

    • Deliver precise concentrations from ppb to high ppm
    • Use Dynacal® permeation devices as the trace gas source
    • Proprietary constant temperature system controls chamber temperature at a set point with 0.01°C accuracy
    • Front panel access to permeation chamber
    • Choice of plumbing and flow configurations
    • Manual and automated versions
    • CE-Certifed (except for Model 120)
  • Configuration

    Base configurations in the table below can be configured to meet user requirements for dilution gas and carrier gas flow capacities.

    Automated ModelsManual Models
    • User sets either the flow rate or the concentration via touch screen
    • Required temperature and concentration or flow rate or set and controlled automatically
    • External gas source
    • Concentrations are calculated manually
    • Required temperatures and flow rates are set manually
    • Internal pump or external gas source
    Model 235Basic
    • Provides continuous dilution
    • Maintains a constant carrier flow through the permeation chamber
    Model 230Basic
    • Provides continuous dilution
    • Maintains a constant carrier flow through the permeation chamber
    Model 345Intermediate/extended concentration range
    • In the zero mode, scrubbed dilution flow is delivered to the outlet, allowing the end user to establish zero before sampling
    • Full range of mode capability
    Model 340Intermediate
    • Zero function as described at left
    Model 450Extended concentration range
    • Mode switch selects among standby (through), zero, span 1 (low concentration), and span 2 (high concentration) modes
    Model 505Dual chamber
    • Two separate permeation chambers with independent temperature control systems
    • Chamber 1 and chamber 2 can run independently, or be used together to combine trace components
    • Solenoid valves allow the carrier flows to be switched from the dilution stream to a vent port, allowing chamber 1, chamber 2, chamber 1 + chamber 2, or zero
    Model 500Dual chamber
    • Two separate permeation chambers with independent temperature control systems
    • Chamber 1 and chamber 2 can run independently, or be used together to combine trace components
    • Solenoid valves allow the carrier flows to be switched from the dilution stream to a vent port, allowing chamber 1, chamber 2, chamber 1 + chamber 2, or zero
