Stand Alone Calibration Station
The SDM-3R Calibration Station is a versatile maintenance tool that automates the service of a GX-3R (Pro) portable gas monitor. This docking station can be used as a stand alone device for charging, calibration and bump testing, with all records stored automatically for future upload to a PC via USB flash drive (PC software and flash drive included).

Multi Module System
Automate how you manage and service GX-3R (Pro) instruments by connecting the SDM-3R to a computer with a USB cable. With the SDM Docking Station controller software, you can simultaneously calibrate, bump test, archive data, or charge up to ten instruments. Also, download the datalogging history from each instrument into one easy to manage locator. SDM-3R stations can be manifolded together to reduce the number of demand flow regulator gas cylinders required.
