Respirometer ER series
A system that measures CO₂ production (and O₂/CO₂ concentration in the flow) during biodegradation under controlled conditions; continuously monitors flow, temperature, pressure, humidity; software calculates CO₂ production and % biodegradation; additional gases can be measured.
Features
- Modular & upgradable; optional gas sensors (e.g., CH₄, H₂S, H₂, NH₃)
- Aerobic or anaerobic; temperature range about +3°C to +70°C
- Multi-channel (12/24/36/48/60); MFC per channel
- Plug & Play; compressor included; auto humidification; leakage alarm; remote control; Excel export
- Optional on-line δ¹³C isotope integration
Respirometer DRI Series
Measures O₂ to determine microbial activity in degradable organic matter under defined continuous airflow and adiabatic conditions; sealed adiabatic vessels create conditions defined by EU and other norms.
Features
- 1/3/6/12 channels; Plug & Play; temperature sensor in each vessel; automatic condensate removal
- Measures temperature/flow/pressure/humidity; O₂ range 0–25% (accuracy stated 2%)
- Multiple vessel sizes; remote desktop control; compressor included; Excel
Soil Flux
Portable/automatic analyzers for simultaneous gas flux measurements (CO₂, O₂, CH₄ and others on request) over a wide dynamic range on various surfaces; suitable for fields, forests, landfills, etc.
Features
- Portable or stationary (automated); lightweight
- Built-in GPS for map positioning
- Compatible with up to 5 different gas sensors (different ranges)
- Operable on tablets/phones/PCs; software allows for on-site flux calculation.
Plastic Disintegration Respirometer - DT
Determines the degree of disintegration of plastics under defined composting conditions in a pilot-scale test.
Features
- Single/Multi-channel: 1/3/6/12; Plug & Play
- Control unit integrated with PC; each reactor has a cooling system
- Measures temperature and flow rate; O2 measurement range 0–25% (accuracy indicated 2%)
- Multiple container sizes; remote desktop control; includes air pump/compressor; Excel export
