JF-1A-ST Handheld Ex Conductivity Meter “Stick Conductivity”

JF-1A-ST Handheld Conductivity Meter (Stick)

Conductivity Measurement of Distillate Fuels

As Per ASTM D2624; IP 274

DEF STAN 91-091; ASTM D1655; ISO 6297

NSN 6625-01-735-6696

JF-1A-ST Stick is a Handheld Fuel Conductivity and Temperature Meter and is the Oil and Gas and Military’s easiest to use, most reliable device. Delivering ASTM D2624 Test Method results in the field with the touch of a button determining the electrical conductivity of distillate fuels anywhere in the world. The Stick Meter also has an optional field calibration verification box that allows the field user to calibrate and verify any Stick Meter for ten years.

JF-1A-ST Features and Specifications...

Advantages of the JF-1A-ST Handheld Stick…

  1. Ex Rated, FMc (NEC), ATEX, IECEx for use in Class 1 Div 2 Environments
  1. ASTM D2624, with highest available accuracy due to AC Measurement Technology.
  1. Provides digital reading of conductivity, and temperature of sample. Values toggle on display for 30 seconds after sample is taken.
  1. AC Measurement technology allows for measurement of conductivity in any sample container, no need to relax fuel.
  1. Long Battery life due to low power consumption and auto power off function. AAA Batteries can be bought locally and replaced easily. (Use Energizer LN92 Batteries Only)
  1. Custom measurement ranges available consult D-2 for options.
  1. Lifetime support from D-2 Inc, including a one-year limited warranty on the equipment. We are here to provide support and offer expertise for the readings you are getting in the field.

 

  1. -30° C to 50°C range allowing a wide range of user measurement locations.

 

  1. Field calibration obtained via IRD data link, no need to open the unit.

 

  1. Full validation/calibration can be obtained via JF-1A-ST-VC-SEF standalone device. Users can avoid the need to send the unit back to D-2 for calibration with SEF Box Option.

 

  1. Ergonomic and rugged design: Easy to use. One button operation and ideal for use in harsh environments even when wearing thick gloves. Fits into standard Jet1 Liter Retain Bottles.
Fits in Fuel Sample Bottles

JF-1A-ST-VC-SEF

Full verification and/or calibration can be performed using the standalone box (-SEF). The SEF box allows for field verification and calibration for multiple Sticks. Each Stick MUST be calibrated a minimum of every 12 months.  Verification can be carried out daily, weekly or monthly depending on the end user’s quality control procedures, The SEF Box calibration period is set for 5 years. Both the Stick and SEF Box are supplied with a hard copy calibration certificate.

 

 Digital Output in pS/m for Conductivity

The handheld conductivity stick automatically displays the measurement reading in pS/m on the internal high contrast OLED screen, which can be easily read in low and bright light conditions.

 

 

 

Digital Output in Celsius for Temperature

An advance feature of the Stick is the built-in temperature sensor. Reporting in degrees Celsius, and as required by the test method,  the sample temperature is also displayed at the end of the test,  toggling between the two reports every few seconds.  Conductivity is a function of temperature, and both must be recorded.

JF-1A-ST-VC-SEF Field Calibration & Verification

The JF-1A-ST “Stick” Handheld can be field verified and calibrated very easily, which means you never have to send your sensor back for calibration services anymore. The JF-1A-ST-VC-SEF is a self contained box (seen in Youtube demonstration video above) that can calibrate and verify the calibration of any Stick Handheld anywhere in the world with the push of a few buttons. The SEF box itself is calibrated to NIST traceable standards and only requires calibration every ten years. Thus you can use the SEF box to calibrate all your handhelds, and never have to send the handhelds back for calibration, just once every five years the SEF box needs a calibration (US Military exclusively gets a 10 year version). This revolutionizes the industry be eliminating the need to ship back a handheld conductivity meter annually. Now once every five years you send back one box, 

The SEF Box can be used to Verify the Calibration
The SEF Box Can Also Calibrate the JF-1A-ST
