SENSYX is our safety detection brand, engineered for RV owners, HVAC technicians, and households that need to detect what they can't see. We build professional-grade propane, CO, refrigerant, and combustible gas detectors using UL-recognized FIGARO sensors from Japan — with modern LCD displays that show exact gas concentrations in real time.
SENSYX began with a simple observation: most RV gas detectors haven't meaningfully evolved in 20 years. Owners still face cryptic LED warnings, premature sensor failures, and replacements that don't fit existing cutouts. We set out to change that.
Every SENSYX unit uses a UL-recognized FIGARO sensor manufactured in Japan, a modern LCD display that shows gas type and concentration in real time, and a form factor engineered to drop into legacy cutouts in under 20 minutes. Today SENSYX serves three audiences: RV owners replacing aging OEM detectors, HVAC technicians diagnosing refrigerant leaks, and safety-conscious households monitoring combustible gas exposure.
Direct replacement for Safe-T-Alert 20-441 / 25-741. Bracket-mounted for any flat surface in your RV or motorhome. Detects both propane and CO; LCD shows real-time gas type and PPM concentration. 75 ppm CO pre-alarm catches buildups well before the industry-standard 150 ppm threshold.
Drop-in replacement for Safe-T-Alert 30-442 / Atwood Series 30. Same propane + CO detection performance as the SRC2000-S in a flush-mount form factor with low-profile finish. 20-minute installation in the existing cutout — no rewiring, no cabinet modification.
Cordless HVAC leak detector with Japan-made heat-dioxide semiconductor sensor. Detects CFCs, HCFCs, HFCs, and modern HFO refrigerants (R-1234yf, R-410a, R-134a, and more). SFD201 adds methane, propane, ethane, and isobutane. USB-C rechargeable, color LCD level display, adjustable sensitivity.
UL-recognized FIGARO sensor components with a 5-year operating life. Every unit ships with a printed retail-sale date so you know exactly when it expires.
Real-time gas type and PPM concentration on every alarm. No more guessing what a blinking LED means — you see exactly what's in the air.
CO pre-alarm triggers at 75 ppm, half the industry-standard 150 ppm threshold — giving you earlier warning before exposure becomes dangerous.
Independently tested to UL safety standards. Wide operating range (−31°F to +150°F) and 8–24 VDC tolerance handle real-world RV conditions.
RV alarms drop into legacy Safe-T-Alert and Atwood cutouts in under 20 minutes — same footprint, same wiring, same mounting holes.
US-based customer service, 30-day returns, transparent pricing, and a 2-year warranty on every unit. Backed by a company you can actually reach.
Travel trailer, motorhome, and Class A/B/C owners replacing OEM gas detectors that have reached end of sensor life or false-alarm too often. Same cutout, modern LCD, real PPM readings.
Service professionals diagnosing refrigerant leaks across residential, commercial, and automotive systems — including modern R-1234yf, R-410a, and R-134a applications.
Homeowners and renters who want reliable detection of natural gas, propane, methane, and other combustible gas leaks — with the same sensor technology used by professionals.
RV alarms and refrigerant detectors trusted by owners, technicians, and households across the U.S.
