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.

I need a gas analyzer which can measure the CH4, CO2, H2, N2. Minimum limit is 0 % and maximum limit= infinite. I need to measure these gas composition in anaerobic digester (laboratory scale small bioreactor).
Thank you for your inquiry about the gas detector. Unfortunately, this meter does not have all the gases listed per your specifications to measure.
