Monitor tracks room environment during experiments.

Room Environment Monitor allows user to keep track of room temperature, barometric pressure, and relative humidity in 4 locations. It can also be used to monitor humidity and temperature in sample gas streams. Audible alarms alerts user about undesirable changes in environment. Monitor interfaces to PC by way of RS232, and supports direct Ethernet connection via built-in web server hardware,...

Respirometer can identify contaminated sites.

Suited for Respirometry experiments on soil, water, and sludge, Oxymax ER uses gas analyzers for oxygen and carbon dioxide, allowing head space gas exchange to be measured directly in up to 10 different chambers/samples. Meter can be used in laboratory with limited bench space or taken on site. In lab, unit connects to Windows PC for experiment configuration and data collection. In stand-alone...

Multi-Gas Mixer blends 2-4 gases into precise mixture.
Electronic Components & Devices

Multi-Gas Mixer blends 2-4 gases into precise mixture.

PEGAS 4000MF blends gasses by utilizing thermal mass flow controllers to provide exact flow of each component gas. System is equipped with internal microprocessor to perform all necessary calculations and provide signals to flow controllers. Front panel rotometer shows flow of mixed gas, and external input for contact closure control shuts off gas flow. With min/max ranges of 0-5 ml and 0-100...

Air Dryer reduces moisture in gas samples.
Fluid & Gas Flow Equipment

Air Dryer reduces moisture in gas samples.

Universal Air Dryer contains condenser and dryer. Air enters condenser where dewpoint of sample gas is lowered below ambient, removing most moisture. Once air has passed through condenser, it reaches tube dryer, which consists of one tube inside another. Gas travels through hydrophilic Nafion inner tube into outer tube containing flow of very dry purge air. Gas leaves dryer at dew point...

Gas Mixer allows precision mixing of up to 4 gases.
Electronic Components & Devices

Gas Mixer allows precision mixing of up to 4 gases.

Pegas 4000MF operates under control of internal microprocessor and utilizes mass flow controllers, which make gas mixture independent of temperature or gas pressure. Gas flow ranges from 100 ml to 20 L/min. Flow controllers' accuracy is 1% with repeatability of 0.2% full scale and require input gas pressures at 30 psi. Front panel gas flow meter (rotameter) confirms level of output gas mixture...

Respirometer measures anaerobic gases.
Test & Measurement

Respirometer measures anaerobic gases.

Anaerobic Respirometer measures 02, C02, CH4, H2, N02, H2S, or CO produced during anaerobic processes. Separate process reactors are connected to sampling chamber via check valve. As pressure in anaerobic reactor increases, gas passes through check valve into sampling chamber, where it can be measured. It can simultaneously measure gas production from one to 80 different reactors. Same...
