Handheld Conductivity Sensor for Jet Fuel (D2 JF-1A-HH model)

Part Number 99708-0

The Seta D2 Handheld Conductivity Sensor (D2 JF-1A-HH model) meets the requirements of ASTM D2624. It provides an accurate and rapid conductivity measurement of distillate fuels; and is specifically designed for testing low conductivity fluids such as aviation kerosene

The analyser can measure fuel electrical conductivities between 0 and 2000 picosiemens/meter (pS/M), although it is optimised and normally used in the 0 to 500 pS/M range. The conductivity analyser is constructed of thermally stable internal electronics and two 316 SS coaxial electrode sensors.


Calibration and Verification
Calibration and Verification is quickly and easily performed using the Conductivity Calibration Kit (99714-0) which fits into the instrument.

The JF-1A-HH Conductivity Sensor incorporates innovative electronics Digital Signal Processing (DSP) techniques to accurately determine the electrical conductivity of fuel products. Conductivity is highly affected by temperature change and reporting temperature with correction is a key requirement of making measurements in accordance with ASTM D2624. The JF-1A-HH Conductivity Sensor allows users to measure samples in any container, such as a bucket or glass jar, offering an accurate portable solution to measuring fuels in tanks, in the field or in the laboratory.

The instrument allows real time sample averaging with trend indicator and the user is provided with a visual reading that the sample has settled to a stable value for improved accuracy of testing. The analyser has integral temperature measurement and compensation which is stored with readings.

An easy to use menu system allows up to 8 samples to be internally stored along with sample temperature, date and time information.

The unit is provided in an industry standard ATEX approved polyamide housing, with built in Lithium Ion rechargeable battery system.
