Dynacalibrator® calibration gas generator, Model 340 features a front panel mode control switch.  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.

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. Standard features on all our models facilitate accurate, reproducible, trouble-free calibrations time after time.
