A system for measuring hydrogen (H) and oxygen (O) including a sample system, a signal processing and system control device, at least one polarograph device and a computing device equipped with software for environmental and biological data analysis incorporating both user-defined and environmental data acquired by the signal processing and system control device. The system measures gas level or exchange (production and/or consumption) in the field or laboratory. In some embodiments, the system uses two Clark-type polarograph devices oppositely polarized with gas-specific polarographic circuits, wherein one polarograph device measures Hgas and the other measures Ogas. In some embodiments, the sample system includes an environmentally-controlled sample housing for accepting the polarograph devices and holding a test sample in a reservoir. The system measures Hor Oexchange in microbial samples, including microbial phototrophs which couple light harvesting to Hand/or Oexchange.
