The CO2METER CO2 gas leak detector is workplace safety equipment for any room where CO2 cylinders, kegs, or carbonators are stored or used. CO2 is heavier than air, accumulates in low-lying enclosed spaces, and is colorless and odorless at dangerous concentrations. A buildup that creeps above 5,000 ppm (OSHA's 8-hour TWA limit) can cause headaches, dizziness, and at higher concentrations, asphyxiation. Multiple fatalities every year happen in bar cellars and brewery cold rooms because nobody installed a detector.

Where to Install

Mount the detector at roughly 12 inches above floor level (CO2 settles low) in any space where compressed CO2 is stored or used: bar cellars, walk-in coolers with kegs, brewhouse fermentation cellars, BIB syrup rooms behind QSR fountain dispensers. One detector per enclosed room is the standard install pattern.

Compliance Context

OSHA workplace exposure limits for CO2 are 5,000 ppm (8-hour TWA) and 30,000 ppm (15-minute STEL). Most modern building codes for commercial bars and breweries require active CO2 monitoring in any room storing more than a small reserve cylinder. This detector helps establish a documented safety system, valuable both for OSHA compliance and for the operator's insurance posture.

Alarm Behavior

The unit continuously samples ambient CO2 and triggers an audible alarm when concentrations exceed safe thresholds. Many models also include a relay output for tying into building HVAC for forced ventilation, and a visible LED indicator for at-a-glance status. Same-day shipping from in-stock inventory.
