The SDM-3R is a versatile calibration and docking station for the GX-3R 4-gas monitors. This maintenance tool automates the service of your GX-3R or GX-3R Pro portable gas monitors.

Stand-Alone Use

This docking station can be used as a stand-alone device for charging, calibration and bump testing of your GX-3R fleet while storing all records automatically for future upload to a PC via USB flash drive (PC software and flash drive included).

PC-Controlled Use

You can also automate how you manage and service your GX-3R (Pro) instruments by connecting the SDM-3R to a computer with a USB cable.
