Columbus Instruments products

The Columbus Instruments Opto M4 is our latest implementation of our popular multi-channel activity monitor that supports a variety of sensor lengths and configurations (successor to the previous generation`s Opto M3). Up to 32 channels are supported providing both ambulatory and total counts for each channel. Communication is via serial RS-422 using the CI Bus protocol (MDI Software). Cabling is simplified by the use of 8 channel hubs that connect to the Opto M4 with 25 pin shielded cables.

Oxymax-C is a special adaptation of the Columbus Instruments Oxymax Deluxe System with features specific to compost research. The instrument incorporates specially designed air-flow and temperature controllers that provide a composting environment that is under very precise control. Oxymax-C automatically regulates air-flow as a means of controlling temperature of the composting process.

The Columbus Instruments’ Micro-Oxymax system is a highly adaptable general purpose closed circuit respirometer. The system monitors the concentration of gas contained within an enclosed head space into which the material being monitored is respiring. Periodic sensing of the gas concentration, along with an equally accurate measurement of the volume of the head space, allows calculations of incremental and accumulated values for consumption and production. The Micro-Oxymax patented design principle provides a sensing threshold near 2 x 10-7 liter per hour.

Our new inexpensive single or dual gas (O2 / CO2) respirometer, the Oxymax ER, is a table top model which can be powered from a 115/220V power line or from a car battery (utilizing a voltage converter). Total power consumption is 50W. The ER-10’s dimensions (14” D x 11.5” W x 7.5” H or 36 cm x 29 cm x 19 cm) and weight (20 pounds or 9 kg) make it convenient to use both in lab and field situations for soil, compost, sludge or wastewater respiration measurements.

Columbus Instruments` Model 180C Gas Analyzer is a modular system that allows for multiple gas and/or multiple sample configurations. Model 180C Gas Analyzer can be configured to monitor O2, CO2, CO, CH4, H2S and H2 (other gases are being added on a regular basis; consult Columbus Instruments with your particular requirements). In addition, up to 80 sample sites may be selected for periodic analysis. The combination of multiple gases and automated sample site selection make Model 180C a versatile gas analyzer for many scientific, commercial and industrial applications.

The Paramax-101 has been discontinued. While we still support the systems presently in the field, we no longer build new systems.

Our new Portable Gas Meter is an inexpensive, battery-operated gas analyzer. Its size (3` x 8` x 11`) makes it easily portable.

Columbus Instruments` PEGAS 4000MF Gas Mixer is a multi-gas mixer, which can blend from 2 to 4 gasses in a precise mixture available upon demand. The PEGAS 4000MF uses thermal mass flow controllers to provide an exact flow of each component gas. The system is equipped with an internal microprossor to perform all of the needed calculations and to provide signals to the flow controllers. The user only needs to enter the total flow and the concentration of each component gas. Front panel rotometer shows flow of mixed gas. External input for contact closure control to shut off gas flow. Options available: Remote control by a PC via RS-232 serial connections and user-programmed overpressure shut off.

Removal of water vapor from gaseous samples prior to measurement is important to assure accuracy. The Columbus Instruments Condensing Air Dryer reduces the vapor content of gas samples to a 1°C dew point. The system has the added advantage of allowing the recovered water to be returned to the point of origin. This is especially important when it is desirable to maintain the moisture content of a sampled environment or when the water contains elements that are important to the process from which the sample has been drawn. Such cases exist in the measurement of soil, sewage and other aqueous solutions.

Columbus Instruments Comprehensive Lab Animal Monitoring System CLAMS is the premiere system of its kind. Incorporating sub-systems for open circuit calorimetry, activity, body mass, feeding, drinking, food access control, running wheel, urine collection, sleep detection, body core temperature and heart rate in an optional environmental chamber: Oxymax/CLAMS is the one-test solution for simultaneous multi parameter assessment of 1 to 32 test animals.
