HGTD Dissolved Gases Sensor

The HGTD-Pro™ dissolved gases sensor it is suited for deployment on profilers and gliders, or in applications where a faster response, smaller and lighter weight instrument for measuring gas tension is needed. The HGTD was designed as an alternative, lighter and smaller, to the Standard GTD-Pro™.

The HGTD is fitted with PSI's fast response pumped patented tubular interface. Note that a source of water flow is required at 3 to 10 liters per minute. Features
  • High precision and accuracy
  • User friendly set-up and operation
  • Low power requirements
  • Light weight and compact size
  • Unique antifouling protection
