Handheld Four Gas Concentration Meter Detects CH4, CO, O2, and H2S.
Handheld Four Gas Concentration Meter Detects Methane (CH4), Carbon Monoxide (CO), Oxygen (O2) and Hydrogen Sulfide (H2S) Levels
- Split-Screen Color LCD
- Intrinsically Safe (Low-Energy) Design
- One-Button Operation
- Auto Zero Calibration
Description
The HHAQ-110 simultaneouslydetects Methane, CarbonMonoxide, Oxygen and HydrogenSulfide making it the ideal devicefor detecting gas leaks in mines,chemical plants, refineries andconstruction tunnels.The HHAQ-110 displays thecurrent level of each gas as wellas the STEL (short term exposurelimit) and TWA (time weightedaverage). Concentration alarmsare programmable in three modes(audible, visual and vibrating). Thecatalytic/electrochemical sensoruses natural diffusion sampling(typical sensor life 2 years).
The HHAQ-110 is powered by arechargeable lithium-ion batteryand includes the charger.
