Ammonia & Chlorine Detectors
Ammonia (NH3) and Chlorine (Cl2) Detectors are specialized for industries that use these toxic gases in large quantities in large industrial daily operations: industrial refrigeration, water and wastewater treatment, and chemical manufacturing. Both gases are toxic, with technical detection challenges that differ from general detectors, requiring specialized instruments with the appropriate sensor technology.

About this category
Ammonia and chlorine detection systems solve specific industrial challenges. Ammonia (NH3): a sharp-smelling toxic gas, lighter than air (rises and collects near the ceiling), flammable within a defined concentration range. Applications: large industrial refrigeration (many food-freezing plants and cold warehouses use ammonia as the industrial refrigerant for its high thermal efficiency), fertilizer manufacturing, petrochemicals, and pulp and paper. Chlorine (Cl2): a yellow-green toxic gas, denser than air (settles low), highly toxic even at low concentrations. Applications: drinking-water treatment (chlorine disinfection), wastewater treatment, pulp and paper bleaching, PVC manufacturing, and industrial-pool disinfection. Detection technologies: gas-specific electrochemical sensors with periodic calibration required. Installation: NH3 normally rises so sensors mount near the ceiling (noting that cold ammonia releases from refrigeration systems can stay low); Cl2 settles so sensors mount near the floor. Specialized features: fast response for early warning, integration with automatic supply-shutoff valves, and output to emergency ventilation. A technical note: electrochemical sensors are gas-specific (NH3-specific or Cl2-specific) and are not interchangeable. Alarm thresholds and installation specifications follow site risk assessment and project requirements — review the product documentation before procurement.
