Year Founded:


Turner Designs Hydrocarbon Instruments, Inc. is the worldwide leader in the application of field portable, laboratory and on-line continuous process monitors for measuring and monitoring hydrocarbons in water. We are in the exclusive business of making laboratory, field portable and on-line instruments based in UV fluorescence technology.

Our staff of experts understands customer needs, problems and applications for monitoring petroleum hydrocarbons in water. Customer satisfaction is our first priority.

Turner Designs Hydrocarbon Instruments is unparalleled in fluorescence (UVF) expertise for the measurement of hydrocarbons in water and soil. Our customers enjoy the benefits of our worldwide exposure, product development and distribution network. We have more UVF instruments in service for oil in water measurement than all UVF competition combined.

We are experts in oil (hydrocarbon) in water monitors for concentrations ranging from ug/L (ppb) to mg/L (ppm). Detection limits for crude oil, gasoline, diesel fuel, jet fuel and fuel oils have been demonstrated at 10 ppb in distilled water. As an example, a large number of our installed systems routinely monitor drinking water for gasoline and diesel fuel at 30 ppb in river water. We routinely customize our systems to meet highly specialized monitoring projects especially in the offshore oil production market.

We maintain an in-house laboratory that is specifically utilized for application confirmation and method development. We utilize in-house instrumentation and expertise to validate instrument performance for customer applications prior to manufacturing and delivering systems worldwide. Essentially, all customer applications are validated prior to instrument shipment to qualify the effectiveness of our products to meet customer needs. This speeds installation start-up and reinforces successful customer operation of our instruments.

We employ highly skilled field support personnel with field service available in all areas of the world. A worldwide support network allows customers to receive regional support for service and applications needs. Service personnel are deployed from regional support centers based in North America, Asia, Europe, West Africa and the Middle East.


DNV Certified

Introducing the World’s ONLY DNV Clean Design Certified 5 PPM Bilge Alarm
The new TD-107 5.0 features self-compensating electronics that corrects for fouling of the sample cell, along with a Cell Condition Monitor to alert crew when cleaning is required. Other features include:

  • Simple and easy maintenance
  • FLUORESCENCE detection technology is resistant to interferences from turbid or dirty water that impact light scatter devices.
  • Substances such as sediment and rust do not materially interfere with the detection of oil in water.
  • FLUORESCENCE detection ensures that the Oily Water Separator is not ‘fooled’ into staying in recirculation mode by false positives caused by silt and other solids.
  • Includes standard alarm relays and 4-20mA output for remote monitoring, along with user-friendly USB data port for review of recorded OCM data.

IMO Certified

Now, there is an oil-in-water monitor that actually measures oil in water and is not affected by suspended solids
The new TD-107 uses our signature FLUORESCENCE measurement technology in a unique new package that can be universally applied to bilge water monitoring. Priced within range of standard light scatter type instruments, the TD-107 is low maintenance, rugged, and has all the features defined by marine customers and regulators including Cell Condition Compensation up to 50% reduction in light transmission, 18mo+ Internal Permanent Memory with data transfer via USB memory stick, 4-20mA output and alarm relays. Memory includes all events and complete ppm vs. time record. It is designed to interface directly with existing mounting for replacement of obsolete OCM technology. Turner Designs Hydrocarbon Instruments, Inc. of Fresno, CA has teamed with NAG Marine of Norfolk, VA for exclusive worldwide sales and service to the marine industry for all bilge alarm applications.
