Founded in 1974, Applied Microsystems Ltd. has a 34 year track record in the field of oceanographic instrumentation.  We supply CTDs and sound velocimeters to military and civilian customers working in the fields of oceanography and hydrography.

What are we known for?  In 1995, Applied Microsystems pioneered the design of the time-of-flight sound velocity sensor.  Today, we are the vendor of choice for sound velocity measurement for a wide range of marine survey organizations and manufacturers of multi-beam, single beam, intrusion detection, and positioning systems. 

In March of 2008, we launched the market's first - and only - field swappable sound velocity sensor.  By listening to our customers, we realized that returning instruments to the factory for recalibration was a significant pain for many organizations.  SV Xchange allows users to field-swap their sound velocity sensors, essentially eliminating instrument down time.  Since that initial launch, we have added to our list of field-swappable sensors with P•Xchange™, C•Xchange™, and T•Xchange™.

Our sensors are high speed, rapid response sensors.  Like the Micro CTD pictured above, all of our instruments have 25Hz sampling, and our sensors all have response times of under 100 milliseconds.  Why is that important?  Read our discussion paper on Salinity Spiking and its relationship to sensor response times.

Over the past 34 years, we have developed a list of engineering firsts that we are proud of.  We are confident that our list of innovations will grow as the years roll forward.
