The HHAQ-110 simultaneously detects Methane (CH4), Carbon Monoxide (CO), Oxygen (O2) and Hydrogen Sulfide (H2S) making it the ideal device for detecting gas leaks in laboratories, chemical plants, refineries and construction tunnels.

The HHAQ-110 displays the current level of each gas as well as the STEL (short term exposure limit) and TWA (time weighted average). Concentration alarms are programmable in three modes (audible, visual and vibrating). The catalytic/electrochemical sensor uses natural diffusion sampling (typical sensor life 2 years).

The HHAQ-110 is powered by a rechargeable lithium-ion battery.

Measurement Ranges:
    CH4: 0 to 100% LEL (Lower Explosive Limit)
