Description
The RKI SDM-Force Calibration Station is a dedicated docking and maintenance hub for the
GX-Force 4-gas monitor. Operating as a standalone device, it automates charging, bump testing, and calibration without a PC connection, storing up to 500 test records on an included USB flash drive for later upload. When connected to a PC via USB, up to ten SDM-Force stations can be daisy-chained to automate fleet servicing and archive datalog data from GX-Force instruments — dramatically reducing manual record-keeping in safety programs.
The SDM-Force includes connections for one to three calibration gas cylinders and PC software (included on flash drive) for automated calibration, bump testing, and datalog archiving from the
GX-Force.
Key Features:
- Stand-alone station
- Charging (Lithium-Ion Battery)
- Calibration
- Bump Test
- 3 Calibration gas ports
- Save Bump Test and Calibration records
- Bump Test and Calibration records copy to USB flash drive
Specifications:
- Input Power:
- Main unit input: 5.2 VDC
- Accessory AC adapter input: 100-240 VAC
- Operating Temperature: 0 to 40 °C (no sudden fluctuations)
- Applicable Instruments:
GX-Force
- Memory capacity: Up to 500 bump tests, calibrations, or alarm checks
- Number of Calibration Gas Cylinders: Up to three calibration gas cylinders
Standard Accessories:
- USB-C cable for instrument connection
- Air Filter
- AC Adapter
- Exhaust tubing
- Flash drive
- USB-A to USB-B cable
- LAN cable
Note: Selection with
Calibration Gas ships via UPS Ground due to HazMat restrictions and isn't available for expedited shipping.
Calibration Gas is not returnable. Please check your selection carefully before ordering.

Frequently Asked Questions
Which RKI instruments is the SDM-Force compatible with?
The SDM-Force Calibration Station is designed exclusively for the
RKI GX-Force portable 4-gas monitor. It is not compatible with the GX-3R, GX-3R Pro, or other RKI instruments. For GX-3R fleet management, see the RKI SDM-3R calibration station.
Can the SDM-Force operate without a PC connection?
Yes. In standalone mode, the SDM-Force charges the GX-Force, performs bump tests, and runs full calibrations automatically, storing records on the included USB flash drive. A PC is only required when you want real-time monitoring, batch scheduling, or to import datalog archives from the GX-Force instruments into the SDM-Force PC software (included).
How many calibration gas cylinders can the SDM-Force handle?
The SDM-Force has ports for up to three calibration gas cylinders simultaneously. This allows automatic sequential purging and calibration with fresh air and up to three different gas mixtures in a single automated calibration cycle — reducing technician time and ensuring consistent results.
How many SDM-Force stations can I connect to a single PC?
Up to ten SDM-Force docking stations can be connected to a single PC using USB cables. This makes it practical to run a large confined space program from one control point — scheduling, bump testing, and calibrating an entire fleet of
GX-Force instruments without moving monitors between stations.
What calibration gas do I need for the SDM-Force?
The SDM-Force services the GX-Force, which detects LEL/O₂/CO/H₂S. The standard calibration gas mixture is 25 ppm H₂S / 50 ppm CO / 50% LEL CH₄ / 12% O₂ in N₂ (RKI part 81-0154RK-04), available separately from PK Safety. Confirm flow rate requirements in the SDM-Force manual before connecting cylinders.
