In-Situ^® Inc. Announces Acquisition of Alpha Designs Ltd
In-Situ^® Inc. is pleased to announce the acquisition of Alpha Designs LTD, Victoria, British Columbia, Canada.

The Alpha Design products are designed for measuring real-time total dissolved gases in water in order to avoid supersaturation of atmospheric gases, such as nitrogen and oxygen. Avoiding supersaturation of atmospheric gases in water is critical to healthy fish populations.
