The RKI SDM-3R is a maintenance tool that automates the service of GX-3R and GX-3R Pro portable gas monitors.
Stand-alone use
The docking station can be used on its own for charging, calibration and bump testing. All records are stored automatically for later upload to a PC by USB flash drive (PC software and flash drive included).
PC-controlled use
Connected to a computer by USB cable and run with the SDM docking station controller software, the SDM-3R can calibrate, bump test, alarm check, archive data or charge up to ten instruments at once. Datalogging history from each instrument can be downloaded to one location. SDM-3R stations can be manifolded together to reduce the number of demand flow regulators and gas cylinders needed.
