D-2 Inc. News & Announcements
August 21, 2009 - New Product! The MicroConD2 Sensor
D-2 Inc. is pleased to introduce the new product line of MicroConD2 sensors. These sensors are designed for in process measurement of conductivity and dielectric constant. These sensors are extremely customizable to be able to be used in a variety of applications. Measures conductivity in various ranges such as (0-2,000 pS/M) or (0-3,000pS/CM), custom ranges available. These sensors are very small and very durable. Only a 4" long, 1" diameter cylinder houses the instrument. This sensor has been designed to be fit axially inside of fuel injectors and aircraft loading nozzles. Utilizing our patented AC Measurement technology this sensor can provide real time in process measurment of conductivity, dielectric constant, and tempurature. See the brochure for more info.
June 30, 2009 - D-2 Inc. JF-1A-HH Handheld is Approved for ASTM D2624
D-2 Incorporated attended the ASTM Conference in Norfolk, VA. We are pleased to announce that the JF- 1A-HH Handheld Conductivity meter has been certified for use in ASTM Method D2624. This means we now offer a handheld and a conductivity meter for measuremnts of Method D-2624. With the highest accuracy available in the method our in line and handhelds provide the most precise conductivity measurments in the industry. See precision study graph on handheld brochure.
March 6, 2009 - Introduction of the New Hydro- Light JF-WA1 Moisture Content Analyzer
D-2 Incorporated is pleased to announce the new design of our popular JF-WA1 Water Pad Tester. The Hydro-Light JF-WA1 is much smaller and easier to through an ASTM Approval process to be added as a supplement to the D3240 Testing Method. This new box measures the free moisture content of fuel in the 0 - 50 ppm range. Hydro-Light is still being reviewed for acceptance into ASTM Method D3240 on a new ballot. The Ballot is scheduled to go out for vote on October 5, 2009. For more information contact dfougere@d-2inc.com.
August 20, 2008 - New Product: JF-1A-HH-CM
We are pleased to announce that our popular Handheld Conductivity Sensor is now available for the higher conductance ranges. With the recent successes of the JF-1A-MR and the JF-1A-HH we decided to combine the two and develop the High Range Hand Held Conductivity sensor. The new Handheld has a range of 0-200,000 pS/M, or 0-200 uS/M. This allows highly accurate hand sampling measurement of liquids with a higher conductance than 2,000 pS/M. Available with a new easy to clean sensor tip for ink applications.
July 10, 2008 - New Product: JF-1A-MR MultiRange Conductivity Sensor (0-200,000 pS/M)
D-2 Incorporated finished development of a new higher range in line conductivity sensor. This sensor was developed due to customer requests for high accuracy conductivity measurement in liquids with a higher conductance. The Multirange sensor is similar to the orignial JF-1A except it has the ability to read much higher conductivity range with the same accuracy as the JF-1A.
July 21, 2007 D-2 Inc. Changes Address
D-2 Incorporated relocates to 19 Commerce Park Road, Pocasset, MA 02559. This relocation was undertaken to secure a greater flexibility in all our departments. D-2 Incorporated’s production processes will have a better throughput and increased quality awareness, which in turn, creates a more reliable product reaching our customer’s hands in a shorter amount of lead time. Additionally, improvements were made in our Engineering and Administrative areas to improve customer support functions.
April 4, 2007 - New Product: JF-WA1 Automated Water Pad Tester (Digital Readout)
D-2, Inc. is pleased to announce the introduction of the JF-WA1 Automated Water Pad Tester. The JF-WA1 is a fully automated pad analyzer designed to measure water content of Gammon free-water test pads.
The JF-WA1 utilizes a LED source-amplified photdiode receiver with microprocessor controlled solid state electronics to provide a fully automated filter analyisis with free-water content displayed on the unit's LCD display. Operation of the instrument is further simplified with the use of the innovative shuttle design.
With the JF-WA1 free water measurement of Aviation Fuel is now a simple matter of placing the shuttle in the analyzer, waiting five seconds and reading the ppm water content on the LCD Display.
If you would like a product demonstration please call us or email dfougere@d-2inc.com.
December 6, 2006 - D-2, Inc. JF-1A Fuel Conductivity Sensor Listed in ASTM D2624
At the winter meeting, in Orlando, Florida, ASTM sub-committee J-04 voted to approve balloting on revised wording of ASTM method D2624 that includes the D-2, Inc. JF-1A in-line sensor for measurement of conductivity in fuels. Following a 5-year process of rigorous field trials, round robin comparisons, and extensive data analysis, the sub-committee has confirmed that the performance of the JF-1A exceeds the repeatability and reproducibility requirements of ASTM D2624 and will now be included in the method. The revised method has been moved from the sub committee to D2 for final ASTM ballot approval. Final completion of the revised method is expected in early 2007. Separate performance monitoring outside the scope of the ASTM tests has also demonstrated the superb stability and reliability of the sensor, with sensors maintaining calibration accuracy over several years of continuous field service. Inclusion of the JF-1A in the method now provides users with the option for a true in-line measurement method, rather than the hand-held or slip-stream methods previously listed. This will have significant impact on the industry by opening several new options for regulatory compliance, quality assurance, and automated process control, where static dissipation additives (SDA) are required. The JF-1A conductivity sensor provides a true in-line continuous measurement of conductivity, with real-time 4-20 mA and RS-232 output capability. With continuous measurement ability, users can now install fully automated or semi-automated conductivity control and quality assurance systems. The JF-1A allows users to maintain safety compliance by assuring conductivity remains within specified limits throughout an entire delivery cycle by providing continuous conductivity measurement. With only periodic sampling it is entirely possible to have widely varying conductivity values throughout a delivery cycle, even though a load average may be within limits. In-line measurement capability also allows automated compliance assurance by providing a continuous record and alarming to out-of-spec conditions. No longer is the user required to manually take and analyze samples throughout the loading process. The JF-1A provides a significant labor saving opportunity for terminals and refineries that are currently required to take numerous conductivity samples. Where automated SDA injection systems are used, the JF-1A can be used as the primary measurement. This will allow users to design feedback control systems, rather than relying on volumetric dosing (which can lead to unintended conductivity variability due to temperature changes and varying fuel response to the SDA). February 2006 - EX Certificates recently obtained - Click here for details
December 2005 - One of our recent installations was for AirBP at their NEREFCO Refinery in the Netherlands. For this installation D-2 Inc. provided a complete packaged injection system for automated injection of Octel's Stadis 450 into a 24" ship delivery line. This was a particularly interesting system in that the requirement was to inject neat (undiluted) additive over a flow range of 100 to 5,000 m3/hr. D-2 supplied an injection system using a variable rate/variable injection volume metering pump, with a feedback control system using the JF-1A sensor as the control signal. The system and all components were ATEX certified.The system uses a single pump to cover the entire injection range. The pump is a Bran & Leubbe unit with variable stroke rate and variable injection stroke volume. We can therefore control both injection rate and volume to end up with about a 50:1 injection turndown ratio. This eliminates the need for multiple pumps. This installation provided control of conductivity to set point +/- 10 pS/m, even with raw(inlet) fuel conductivity values varying by well over 150 pS/m.
