Docking Stations and Accessories MX4


The DSX™ and V•Cal™ Docking Stations offer fully automatic or semi-automatic calibration and bump-test functions. The DSX Docking Station can function as a standalone, cloud-connected or server-connected fully automatic calibration and bump-test attendant. Additionally, The DSX will retain all vital records as well and act as a battery charger whenever an instrument is “docked”. Cloud- or server connected versions make data and software updates available to you wherever you are and seamlessly interface with the iNet® platform. Connected versions can even handle replenishing calibration gas automatically.

The V•Cal is a semi-automatic station that will calibrate or bump-test a docked instrument with the push of a single button. Choose from single-unit or a 6-unit station. Data storage and configuration is simple with the use of our accessory software. An accessory printer is available for reports on the job-site.
