RKI GX-3R Hand Aspirated Sample Adapter 81-1161
Description
The RKI 81-1161 Hand Aspirated Sample Adapter allows users to manually draw gas samples into the
RKI GX-3R multi-gas monitor without a motorized pump. Attached to the instrument's inlet, the adapter is used with a squeeze-bulb or syringe-style aspirator to pull sample gas from confined spaces, enclosed areas, or locations where atmospheric entry has not yet been deemed safe. This is a key pre-entry testing tool for confined-space programs operating under permit-required entry procedures.
Compatible with:
RKI GX-3R multi-gas monitor
Function: Hand-aspirated (manual) sample draw
Part number: 81-1161
Frequently Asked Questions
What is the difference between hand aspiration and a motorized pump for gas sampling?
A motorized pump (such as the RKI
RP-3R) draws sample gas continuously and is appropriate for ongoing monitoring. Hand aspiration uses a squeeze bulb or manual syringe to pull a discrete gas sample through the sensor assembly. Hand aspiration is often used for initial pre-entry testing of confined spaces when continuous pump operation is not needed or when a motorized pump is not available.
Is the 81-1161 used for pre-entry confined space testing?
Yes. Pre-entry atmospheric testing is required by OSHA 29 CFR 1910.146 for permit-required confined spaces. The 81-1161 adapter, used with tubing, allows the attendant to test the atmosphere from outside the space before entry. Oxygen levels must be at or above 19.5% and below 23.5%, combustible gases below 10% LEL, and toxic gases (such as H2S) below their ceiling values (OSHA H2S ceiling: 20 ppm) before entry is approved.
Is there a separate hand aspirated sample adapter for the
GX-3R Pro?
Yes. The
GX-3R Pro uses the RKI 81-1162 Hand Aspirated Sample Adapter, which is a different part number from the 81-1161. The
GX-3R and GX-3R Pro have different inlet configurations; do not substitute one adapter for the other.
What tubing length is recommended for confined-space pre-entry sampling?
RKI recommends tubing lengths appropriate for reaching the bottom, middle, and top zones of the confined space — typically 10 to 20 feet of sampling tubing. Longer tubing increases the volume that must be aspirated to draw a fresh sample from the remote measurement point. Consult your confined-space entry plan for site-specific requirements.

GX-3R?
