Anaerobic Monitor CAM12


The Coy Anaerobic Monitor (CAM-12) is the only analyzer that offers both O2 (PPM) and H2 (%) monitoring in one unit for the same price as most conventional Oxygen monitors.

Features :

  • Detects real-time transient level changes
  • Adjustable alarm levels
  • User replaceable sensors

More details



The CAM-12 (and it’s predecessor, the Model 10) Analyzer have been successfully used by researchers to monitor levels of the oxygen and hydrogen in their anaerobic chambers for over 25 years.  Your anaerobic chamber becomes a dynamic environment in which you can readily determine leaks, bad catalyst or a need for change in equipment layout or airlock procedure.  The H2 monitor allows each lab to optimize their Gas Mix consumption rate saving time and operational cost.

Now labs who might otherwise have wanted separate, costly equipment to measure hydrogen can reap the additional benefits of knowing the levels of this volatile gas. Each analyzer is especially calibrated to your specific background gas mix. The security of knowing that an incorrect gas mixture can’t jeopardize your equipment or your safety is priceless.

* If you are using a gas mix containing anything EXCEPT Hsub>2, Nsub>2 and/or <20% CO2, consult Coy Laboratory Products as this is outside of the standard CAM-12 range; however, a CAM-12S may be appropriate for your application. The CAM-12S is calibrated for use with gas mixes containing argon and/or >20% CO2 (the CO2 compensation function is potentially inaccurate or nonfunctional depending upon the gas mix).
