[@ramananthm4624]

Excellent explanation

[@malarrajah]

Could you please explain about the C value test procedure. Thank you

[@ElcometerOfficialChannel]

Thank you for your comment, @malarrajah. Could you please clarify on what you mean in regards to your comment?

[@jamesosaro5312]

Good one

[@PINTURAINDUSTRIALRODRIGUES]

Very good!

What is the standard for limiting salt content in blasting sand, for example copper slag? Please reply😊

[@ElcometerOfficialChannel]

Hi, This would be determined by your job specification and / or your blasting sand supplier. If you have any more questions, please get in touch at [e-mail]

[@shuvrowalam]

Would you please describe (or give the link of video if any) how to calibrate elcometer 13E ?

[@ElcometerOfficialChannel]

Thank you for your comment. There are instructions on how to calibrate the Elcometer 138E Conductivity Meter in the Elcometer 138 Basic Bresle Kit Instruction Book. You can view the book by clicking on this link: www.elcometer.com/images/stories/PDFs/MultiLingualInstructionBooks/138_Basic.pdf Simply go to page en-10 (section 5.6 CONDUCTIVITY CALIBRATION) to read instructions on how to calibrate the meter. If you have any further questions, please contact [e-mail] or visit www.elcometer.com/contact-us to find your local Elcometer distributor.

Hi As per ISO 8502-6, Table A-1 (Annex A) for A-1250 Patch which is indicated in Elcometer 138 instructions manual the volume of injected water to be 14.9 ml (+ - 1 ml). Why do you specify 3 ml water?

[@ElcometerOfficialChannel]

Hi, Annex A for A-1250 refers to a leak test, meaning more water must be injected. For working inspection test we advise injecting 3ml as per ISO 8502-6 If you have any more questions, please get in touch at [e-mail]

[@acapulcoscebu449]

does this test for chorides , sulphates and nitrates

[@ElcometerOfficialChannel]

Hi, Thank you for your comment! Yes, it does test for all three and provides a result of all three in a single metric. If you would like to measure them individually you would need to use our CSN kit available here: www.elcometer.com/en/coatings-inspection/all-coatings-inspection/inspection-kits/elcometer-134-csn-chloride-sulphate-nitrate-test-kit.html If you have any further questions please email [e-mail]

[@darylstaples8409]

I just done an Icorr exam and one of the questions from what I remember was regarding the thickness of the patch 1mm, 1.5mm, 5mm, 10mm I’m sure I got the answer wrong and I cannot find the information😅

[@ElcometerOfficialChannel]

Hi, Thank you for the comment! The answer you are looking for is 1.5mm. If you have any further questions, please get in touch with our tech team at [e-mail]

[@elumalaielumalai08]

Why should we multiple original value with 1.2 and 1.1?

[@ElcometerOfficialChannel]

Hi, We multiply the original value with 1.2 and 1.1 because the measured conductivity is converted to surface density of salts using the ISO Salt Mix or IMO PSPC equivalent NaCI conversion factors. ISO Salt Mix: mg/m² = x1.2 µg/cm² = x0.12 IMP [S[C equivalent NaCl mg/m² = x1.1 µg/cm² = x0.11 For further information, please get in touch at [e-mail]

[@irfananwar7147]

What is maximum acceptable limit for salts before or after coating?

[@ElcometerOfficialChannel]

Hi, These limits are specified by your particular job specification and possibly the paint data sheet. Defined standards are yet to be created for this kind of test. For more information please get in touch @[e-mail]

[@harvishtechnicalservices1609]

In Batch certificate, the mean ionic concentration values (Cleanliness) shall be deducted or not??

[@ElcometerOfficialChannel]

Hi, We can confirm that the Mean Ionic Concentration should be deducted from the final test. If you have any further questions please get in touch @[e-mail]

[@Jawahar1995]

What if we get more chloride than the specified limits in our specifications? What is the solution after getting higher chloride levels?

[@ElcometerOfficialChannel]

Hi, If your chloride levels exceed specified limits we suggest thoroughly washing the surface using deionised water, and then repeating the test. Please ensure you are conducting the test accurately and precisely as per the video. If you have any more questions, please get in touch at [e-mail]

[@praveenpappa4683]

@@ElcometerOfficialChannel after repeating the test, should it required blasting again? because there may be a chance of flash rusting on the surface if the surface washed using deionised water? Please advice. Normally at site, subcontractor is washing with portable water and re-blast the surface to achieve the cleanliness.

[@ElcometerOfficialChannel]

Hi, Whether you need to wash again really depends on the results of the brestle patch. If the salt level is unacceptable they'll have to wash again

[@phonghoang1432]

Please give some detail explanation why ISO 8502-6 and IMO PSPC requires 2 different convert factor 1.2 and 1.1 respectively?

[@ElcometerOfficialChannel]

Thank you for your comment. As it explains in the instruction manual for the Elcometer 138 Bresle Salt Kit, ISO 8502-6 is a conversion for a mix of salts (so all soluble salts), whereas IMO PSPC is looking for the density of sodium chloride only, hence the difference. If you have any further questions please contact [e-mail] or visit www.elcometer.com/contact-us to find your local Elcometer distributor.

[@Dingzerovn]

Are Elcometer E138CM (Conductivity Meter) or E138BSM ( Bresle Salt Meter) temperature compensated? Because I don't see the statement in datasheet or use guide?

[@ElcometerOfficialChannel]

Thank you for your comment. Both the Elcometer 138 Conductivity Meter and Bresle Salt Meter are temperature compensated to 25°C (77°F). For more information please contact [e-mail] or visit www.elcometer.com/contact-us to find your local Elcometer distributor.

What's ER4 error?

[@ElcometerOfficialChannel]

Hi, ER4 suggest there has been a calibration failure - this is typically due to the ranges being too far out from the known calibration solutions, or possibly a sensor error. We would suggest recalibration. If this still doesn't work, please get in touch at [e-mail]

單位是ms，要如何轉換mg\m2

[@ElcometerOfficialChannel]

Hi, 1 microsiemen is 0.001 millisiemens Therefore 1mS is equivalent to 1000μS. For further information please contact tech support @[e-mail]
