 | A modular system that allows for measurement of gas concentrations from multiple points (1 to 80) |
 | A paramagnetic sensor based oxygen analyzer capable of monitoring over the range of 0-100%, with 0.001% stability |
 | An inexpensive, battery-operated gas analyzer. It can simultaneously measure O2, CO2, and CH4 gases evolving from compost or landfill and can measure concentrations of O2, CO2, and CH4 in the range of 1 to 100% |
 | A gas blender that provides a continuous flow of mixed gases from pure gas sources |
 | Reduces the vapor content of gas samples to 1oC. Removal of water vapor from gaseous samples prior to measurement is important to assure accuracy of gas concentration measurment |
 | A special adaptation of the Columbus Instruments Oxymax Deluxe System with features specific to compost research |
 | An inexpensive single or dual gas (O2 /CO2) Respirometer, is a table top model which can be powered from a 115/220 V power line or from a car battery |
 | A highly adaptable general purpose closed circuit respirometer with very high sensitivity |
