Mass Flow Controllers & Gas Mixers
|
 |
|
Our mass flow control units allow you to set precise rates of mass flow for respirometry, process control, and gas mixing applications. They interface with industry-standard mass flow control valves and can be operated in stand-alone mode. They are also fully computer controllable for applications requiring sophisticated flow or mixing profiles.

Mass Flow Generators
|
 |
|
Our mass flow generators combine calibrated, linearized mass flow meters with variable-speed air pumps. Sophisticated computerized modulation of the pump controls the mass flow rate of air to yield a precise flow rate set by the user. Pump wear is minimized and reliability is maximized. All of our mass flow generators can operate in stand-alone or computer controlled mode.

Flow Dividers
|
 |
|
Primarily intended for push-mode respirometry systems, our flow dividers allow you to split multiple flow rates from a single high pressure source such as compressed air or a pump. They are economical alternatives to multiple mass flow control valves.

Mass Flow Meters
|
 |
|
Our mass flow meters measure mass or molar air flow rate, and therefore do not require barometric pressure or temperature correction. Relative to normal industrial-type mass flow meters, our mass flow meters have the advantages of both analog and serial outputs; multiple output ranges; adjustable digital filtration; and easy, menu-driven, stand-alone calibration options.

Subsampler
|
 |
|
Our subsampling unit combines a linearized mass flow meter, a needle valve, and a variable speed pump. Intended primarily for subsampling applications (pulling or pushing an air stream through one or more gas analyzers), the subsampler can also be used as an inexpensive primary flow generator for budget respirometry systems.

PP-2 Bench/Field Pump
|
 |
|
The PP-2 dual pump system provides two reliable, variable-speed diaphragm pumps that operate on 12 VDC (adapter included). It is ideal for generating flows of up to 3 liters/minute per pump for respirometry and gas sampling applications.
