The Dwyer A-RSME-BOX is a surface-mount enclosure for the Dwyer Series RSME Room Status Monitor — allowing the RSME to be installed in applications where flush in-wall mounting isn't possible or practical. The box mounts directly to the wall surface, and the RSME snaps onto the front face exactly as it would with the standard flush-mount junction box. Conduit can enter from either side or the back, depending on wiring path requirements.
This is the right accessory for concrete or masonry walls where cutting a flush opening is impractical, retrofit installations in existing facilities without behind-wall access, temporary or relocatable installations, and specialty environments (vivariums, BSL containment, modular cleanrooms) where wall penetrations need to be minimized. The box is compatible with all 24 RSME variants regardless of accuracy tier, range, or bezel option.
Concrete or masonry walls (no flush cutout possible), retrofit RSME installations in existing facilities without behind-wall access, modular cleanroom or vivarium installations where wall penetrations need to be minimized, and temporary or relocatable monitoring stations where the RSME may need to be moved between locations.
Key Features
Works with every Dwyer Series RSME Room Status Monitor — both accuracy tiers (±0.5% and ±1.0% RSS), all six pressure ranges, and both bezel options (plastic and brushed stainless steel). No SKU matching required — this single accessory fits the full RSME lineup.
Replaces the flush-mount junction box that ships standard with each RSME. The A-RSME-BOX mounts directly to the wall surface using standard fasteners (not included); the RSME then snaps onto the front face just like a flush installation. No special tools required.
Multiple conduit knockouts on the side panels and back of the box accommodate flexible wiring paths. Run conduit through the wall behind the box for clean installations, or enter from the side for exposed conduit applications.
Same flame-retardant ABS plastic used in the RSME back housing — matched color and finish for a clean integrated appearance. Fire-rated to UL 94 V-0 for installation in commercial and healthcare facilities.

Frequently Asked Questions
The A-RSME-BOX is a surface-mount enclosure that replaces the flush-mount junction box shipped standard with each Dwyer Series RSME. You need it when in-wall flush mounting isn’t possible — concrete or masonry walls where cutting a recess is impractical, retrofits in existing facilities without behind-wall wiring access, modular cleanrooms or vivariums where minimizing wall penetrations matters, or temporary installations where the RSME needs to be relocatable.
All 24 of them — both accuracy tiers (±0.5% RSS B-series and ±1.0% RSS C-series), all six pressure ranges (0–0.5, 0–1.0, 0–2.0, ±0.5, ±1.0, and ±2.0 in w.c.), and both bezel options (plastic and brushed stainless steel). One accessory fits the entire RSME lineup.
Instead of. The RSME ships with a flush-mount junction box designed for in-wall installation. The A-RSME-BOX is an alternative for surface-mount installation — pick one or the other based on your wall type and access. The standard flush box is fine for most drywall installations with behind-wall wiring access; the A-RSME-BOX is the right choice when flush mounting isn’t practical.
No — the box itself ships alone. Wall fasteners (anchors or screws appropriate for your wall material) and any conduit fittings, locknuts, or strain reliefs need to be specified separately based on your installation. The box has multiple knockouts on the sides and back to accommodate flexible conduit routing.
Yes — same flame-retardant ABS UL 94 V-0 plastic used in the RSME back housing, matched white color. When installed, the A-RSME-BOX and the RSME mounted on it appear as a single integrated unit on the wall surface.
