Metabolic Monitor System
Model MM-100

The MM-100 Metabolic Monitor is a complete system for measuring oxygen consumption in the small animal. Using the latest technology in paramagnetic O2, infrared CO2, and thermal mass flowmeter analyzers, it automatically computes O2 consumption, CO2 production, and respiratory exchange ratios (RER).
SIMPLE SET UP AND OPERATION
The animal is placed in the provided chamber and allowed to equilibrate for 5 - 10 minutes. All gas and flow measurements, and computed results are shown on the front panel LCD display panel. A serial port connection sends the measurements to any attached computer. Using the included Win95/98 software, the readings for O2 consumption and CO2 production, along with their moving time averages, are plotted. Data can be logged to simple ASCII files for further spreadsheet analysis using MS Excel or a similar program. Standardization against room air is automatically performed at intervals, so the accuracy of the system is maintained for long intervals of monitoring.

Front panel display panel shows all gas, flow, and computed measurements, as well as elapsed time and chamber being monitored.
 
Multiple chamber systems: Expansion to multiple animals is straightforward. Using the MMX-4 or MMX-16 (for four and sixteen animals, respectively) expansion units, gas sampling and measurement is automatically sequenced between the chambers. This results in an accurate, economical system for screening large numbers of animals for these important physiological parameters.

Communications: Besides sending the measurements and computed results through a serial interface, the "raw" analog signals for O2, CO2, and chamber airflow are also available. These can be monitored by a data acquisition board for custom setups or integrating with other variables (such as activity or feeding behaviors). For complete external control of gas sampling, calibration, etc., a logic interface is provided so all measurement timing can be externally controlled.

Rear panel connectons provide complete access to analog signals, serial port, digital control interface, and expansion interface for multiple-chamber systems.

COMPLETE PACKAGE
The MM-100 comes complete with all necessary components for a single-chamber measurement. This includes the main MM-100 unit, small animal chamber, air pump, drying tubes, and required tubing. The only consumable item is the Drierite material for drying the gas sample.
