RKI Instruments Regulator with Gauge 81-1050RK
Description
The RKI Instruments Regulator with Gauge provides a calibrated, knob-adjustable gas flow with a built-in pressure gauge for use with calibration gas cylinders. Two variants cover the two most common cylinder connection types used with RKI monitoring equipment:
-
81-1050RK — For 17L and 34L steel cylinders (CGA 600 female-threaded connection). Flow rate: 0.5 LPM.
-
81-1051RK — For 34AL, 58AL, and 103L aluminum cylinders (C10 male-threaded connection). Flow rate: 0.5 LPM.
The integrated pressure gauge lets you monitor remaining cylinder pressure during calibration, helping you anticipate when a replacement cylinder is needed before a calibration session runs short. The knob gives precise manual flow control — important when performing field calibrations on RKI portable gas monitors that require exact inlet-flow rates to meet sensor accuracy specifications.
This regulator is compatible with RKI's standard calibration gas mixtures for the GX-3R, GX-3R Pro, GX-2009, Eagle 2, and other portable monitor families. Pair with RKI's 4-gas calibration mixture and the GX-3R/GX-3R Pro Calibration Kit for a complete field-calibration setup.

Frequently Asked Questions
What is the difference between the 81-1050RK and 81-1051RK regulators?
The 81-1050RK uses a CGA 600 female-threaded connection for 17L and 34L steel cylinders. The 81-1051RK uses a C10 male-threaded connection for 34AL, 58AL, and 103L aluminum cylinders. Both deliver 0.5 LPM flow and include a built-in pressure gauge and knob. Check your cylinder type before ordering.
Does this regulator work with a demand-flow or fixed-flow setup?
This is a fixed-flow regulator delivering a continuous 0.5 LPM stream. It is suited for manual calibration procedures where you control the flow with the knob. For automated docking-station applications or monitors that require demand-only flow, RKI's demand flow regulator is the appropriate alternative.
Which RKI monitors can I calibrate with this regulator?
This regulator is compatible with the full range of RKI portable monitors that accept external calibration gas at 0.5 LPM, including the GX-3R, GX-3R Pro, Eagle 2, and GX-2009. Always verify your instrument's required inlet-flow rate in the monitor's user manual.
How do I read the pressure gauge on this regulator?
The gauge indicates remaining cylinder pressure in PSI. As gas is consumed, pressure drops steadily. When pressure falls below the manufacturer's recommended minimum, the calibration gas concentration may be lower than specified — replace the cylinder before calibrating to maintain sensor accuracy.
