The advantages would be significant. Manually calibrating every fixed monitor in a facility is a time consuming distraction from your core business. The units may be in hard-to-reach places creating additional safety hazards. These and other obstacles make it difficult to follow industry best practices for routine testing and calibration. iTrans™ DS2 Docking Station™ is the first system to automate calibration, record-keeping and instrument diagnostics for fixed-point gas monitors. Hands-off maintenance and a snapshot view of your entire gas monitor fleet allow you to: • Maintain your gas monitors more safely, efficiently and reliably • Increase equipment reliability • Eliminate safety concerns • Save money on calibration and testing • Focus more resources toward your core business A graphical user interface tool allows an administrator to view operations on each Docking Station from a network computer. From here, you can initiate calibrations and instrument tests remotely, print reports, set events, and run diagnostics for any or all instruments at any location. The DS2’s flexible architecture minimizes installation costs, whether you’re managing one instrument or an entire fleet of fixed-mounted or portable instruments.
