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.

Measurement Ranges:
    CH4: 0 to 100% LEL (Lower Explosive Limit)
    CO: 0 to 1000 ppm
    O2: 0 to 30% by volume
    H2S: 0 to 100 ppm
Measurement Accuracy: ±2% offull-scale value
Response Time: < 30 seconds to 90%of final value
Alert Levels: 200 ppm STEL +35 ppm TWA for CO, 15 ppm STEL +10 ppm TWA for H2S
High, Low Alarm Ranges:
    CH4: 25 to 80% LEL with 50% LEL default, 10 to 25% LEL with 20% LEL default
    CO: 100 to 500 ppm with 200 ppm default, 25 to 100 ppm with 35 ppm default
    O2: 22.5 to 24% by volume with 23.5% default, 16 to 19.5% by volume with 23.5% default
    H2S: 15 to 30 ppm with 15 ppm default, 5 to 15 ppm with 10 ppm defaults
Sensor Type: Catalytic (CH4), electrochemical (CO, O2, H2S)
LCD Size: 42 mm (1 5/8") diagonalOperating Life with Fully

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).

Asked by: Muhammad Usman
Thank you for your inquiry about the gas detector. Unfortunately, this meter does not have all the gases listed per your specifications to measure.
