When you’re responsible for issuing confined space permits or maintaining gas detection across a large facility, the equipment you choose needs to match the specific chemical risks present in your operation—not just the obvious ones. At GasDog, we manufacture a full range of portable and fixed gas detectors designed to handle common combustibles like Methane (CH4) and Hydrogen (H2), while also addressing the less frequent but equally critical hazards such as Hydrazine (N2H4) in aerospace applications or Phosphine (PH3) in semiconductor manufacturing.
Take our portable 4-in-1 gas detectors, which are standard kit for entry teams working in petrochemical tanks or wastewater lift stations. These units simultaneously monitor Oxygen (O2) deficiency, explosive levels of Hydrocarbons (HC), and toxic gases like Hydrogen Sulfide (H2S) and Carbon Monoxide (CO). But we also go a step further. For facilities dealing with disinfection byproducts, we offer dedicated Chlorine Dioxide (ClO2) sensors that resist cross-sensitivity from other oxidizers. For refineries, our Benzene (C6H6) monitors use PID technology to detect aromatics at sub-ppm levels—something a standard LEL sensor simply cannot do.
In industrial refrigeration, where Ammonia (NH3) leaks pose both toxicity and flammability risks, our fixed monitoring systems can be configured with remote sensor heads placed directly at compressor seals and valve stations. These connect back to central controllers with relay outputs for ventilation or alarm activation. Similarly, for power generation or brewing facilities, our NDIR Carbon Dioxide (CO2) sensors provide long-term stability without the drift issues common in electrochemical cells, making them ideal for areas where inert gas asphyxiation is a concern.
We also address the challenges of reactive gases. Chlorine (Cl2) and Sulfur Dioxide (SO2) are widely used in water treatment and bleaching, but their corrosive nature can shorten sensor life. Our electrochemical cells are engineered with enhanced electrolyte formulations to maintain accuracy over extended deployment periods. For ethylene (C2H4) monitoring in fruit ripening warehouses or acetylene (C2H2) detection in cutting operations, we offer catalytic sensors calibrated specifically for those gas signatures, ensuring you're not guessing when alarm thresholds are crossed.
All GasDog instruments are available with ATEX and IECEx certifications for hazardous locations, and our fixed transmitters support Modbus and HART protocols for seamless integration with existing PLC and SCADA infrastructure. Whether you need a simple portable monitor for daily rounds or a fully networked fixed system covering an entire process unit, the hardware is backed by technical support from engineers who understand both the equipment and the environments it operates in.
