PT Marker

Does anyone know of a marker (preferably pencil) which will fluoresce and is low in sulpher? We have tried the high purity felt tipped markers but: #1 they don't fluoresce, #2 if the tip is depressed a bit too long they create quite a mess and #3 the ink comes off the part too readily with solvent when checking indications. Any information will be much appreciated.

After discussing this with my co-workers, we would also be satisfied if we could find a marker (pencil) which would be low in sulfur and stay on a part in the presence of a solvent. We can live without the fluorescence.

Re: PT Marker
We use a Markal Paint stick with the end sharpened with a knife and use it to mark underwater when doing a UT immersion test. When you remove it from the water the paint dries and will remain.
This might work for your application.

Re: PT Marker
Hello,

We use a red Berol 165T china marker. It fluoresces and is not readily removed by de-natured alcohol. It can readily be removed with mineral spirits. It is one of the approved markers for pre-service inspection of compressor components in a combustion turbine. However, I cannot attest to the Sulfur content.

Regards,
Tom

We have found Sanford Corp. #02435 Orange pencilworks great for FPI and MPI.
