RKI SDM-3R Calibration Station

Stand Alone Use

The SDM-3R 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).

PC-Controlled Use

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, alarm check, archive data, or charge up to ten instruments. You can also download the datalogging history from each instrument into one easy to manage location. SDM-3R stations can be manifolded together to reduce the number of demand flow regulators gas cylinders required.
