The Pen

With the cap on, shake the pen for 10 or 15 seconds to activate the ink flow. Pull off the cap and, with the pen in marking position, give it a little squeeze. This is how you feed and control the ink. For a little dot, a little squeeze; For a continuous line, a continuous squeeze. To do lettering, just keep the tip of the needle wet and draw the lines. When you release the finger pressure, the pen will suck the ink out of the needle point.

Used in a variety of industries including, electronics, medical, horticulture, agronomy, apiculture, communications, aerospace, military, art, and a variety of other industries. It’s application has been very wide throughout the world.

The Needle

There are three different size needles available. The standard needle is 1” in length and has an orifice of 0.031”. It has an output of approximately 12,000 dots. The microtip needle (M) is 1” in length and has an orifice of 0.013”. It dispenses over 25,000 dots. For the smallest dot or for fine lettering the microtip is easier to use. The long tip needle (L) is 3.25” in length with an orifice of 0.031”. The long tip needle is useful in hard to reach places.

The Ink

RoHS compliant, flexible, non-toxic, and non-staining. Most of these inks use water as a base carrier instead of solvents, so they do not contribute to atmospheric contamination. Drying time will depend on the amount of ink dispersed. If you maintain the moisture level of the ink, you can use it to the last drop. The Permanent, Removable and Solvent Resistant inks do not polymerize until the water is evaporated.

Most of the inks are normally the consistency of thick cream. The Metron Marker® is available in four different types of water-based ink: 1) Removable; 2) Permanent; 3) Solvent Resistant; and 4) Liquid 2-Way Tape. The inks are water based and after an extended period of time, may tend to thicken as they lose water. To thin the ink to the consistency of cream, place a drop of water in the opening of the cap and suck it up with the tip of the pen. Vigorous shaking (with cap on) will mix the water and the ink. Warming the pen under a lamp (or in hot water) will make the ink flow and mix more rapidly.

Both the Solvent Washoff ink and Aquaclean are alcohol based and may be thinned if necessary with alcohol.

The Metron Marker Inks are electrically nonconductive. The extreme brightness of the colors results from highly fluorescent pigments which convert energy from the blue and ultraviolet range beyond the visible spectrum into very pure emitted light at narrow waveband wavelengths in the visible spectrum. They also reflect as well as emit these same wavelengths to produce the extremely bright and intense colors. Metron Marker Inks will withstand temperatures of up to 350 degrees Fahrenheit before discoloring.

Metron Inks are available in the Metron Marker®, Pints, and Gallons.

Permanent Ink

Permanent ink has become a standard for marking errors on printed circuit boards in electronic companies worldwide. Permanent ink is a water based, flexible, non-conductive and water resistant ink which may be applied from our Metron Marker pen to almost any surface including Teflon, and even where an oily film is present. Adhesion will, of course, vary with the surface to which it is applied. Waterproof, non-toxic, and flexible, Permanent ink is used in electronics, medical, aerospace, communications, museums, horticulture and various other industries. Permanent ink may also be used as a Torque Seal, for vibration proofing or for tamper proofing. Permanent ink is available in Red (P1), Green (P2), Orange (P3), Blue (P4),Yellow (P5), Brown (P6), Violet (P7), Grey (P8), Black (P9), White (P10), Gold (P11), Silver (P12)and Transparent (P13). Our Transparent Ink (Metron Marker Transflour) fluoresces blue under Ultraviolet light and comes standard in Micro-tip. Available in Standard-tip and Micro-tip (Gold and Silver not available in Micro-tip).

Removable Ink

Our REMOVABLE INK, when dry, can be flicked or snapped off with the fingernail. It can also be removed with a cloth or stiff brush dampened in water or almost any solvent. The binder in the ink will dissolve but the pigment itself is not soluble in most solvents so, therefore, it will not bleed or stain. It is intended to be an easily removable, non-destructive ink.

Removable ink is available in Red (R1), Green (R2), Orange (R3), Blue (R4),Yellow (R5), Brown (R6), Violet (R7), Grey (R8). Available in Standard-tip and Micro-tip.

Solvent Resistant Ink

THE SOLVENT RESISTANT INK is an entirely unique kind of marking liquid with some remarkable resistance to a wide range of solvents and extremely good adhesion to some difficult materials. It will withstand boiling in Trichlorethylene, Acetone, Carbon Tetrachloride, Methyl Ethyl Ketone, alcohols, Freon, Benzol, Cyclohexane and virtually any known organic solvent. It does not etch or attack most surfaces. It has exceptionally good adhesion to glass, quartz, ceramics, aluminum, steel, stainless steel, galvanized steel, solder, chrome and most plastics including polyethylene. It will even mark on Teflon if a very light oil film is applied to the Teflon.

Solvent Resistant ink is a non-toxic, water based, one part ink with indefinite shelf life so long as moisture loss is replaced. It requires no hardening or baking. It will withstand about 350ºF. before the fluorescent pigments begin to change color. Solvent Resistant inks (except black, red and white) when applied on glass or plastic surfaces and heated in air above 200ºF may become water resistant as well as Solvent Resistant. If you intend to remove it with water don’t bake it.

When the Metron Marker® with Solvent Resistant ink stands motionless, the pigments will separate in a few hours. There is a “shaker” in each pen which will readily put the pigment back into uniform suspension when the pen is shaken. Solvent Resistant ink when dry is relatively hard but soft enough to permit a sharp object to scratch through it without chipping off the rest of the mark. Solvent Resistant ink may be removed easily and completely in HOT WATER, providing it has not been baked. The Solvent Resistant ink is so unique it is Patented.

Solvent Resistant ink is available in Red (SR1), Green (SR2), Orange (SR3), Blue (SR4),Yellow (SR5), Black (SR6), White (SR7). Available in Standard-tip and Micro-tip.

Aquaclean Ink

Flushes off very easily and thoroughly with hot water, our AquaClean Ink formula is a very thick, fast-drying ink. AquaClean ink is a specialized ink that was originally developed for use on G10 glass filled epoxy P.C. Boards used for military applications. It is used for marking faults (such as incomplete flux removal) where the P.C. Board will then go through Freon or Trichlorethane degreasers. The AquaClean ink must withstand such degreaser action so that the fault (traces of flux) can be rechecked after degreasing. Final cleaning is done with hot water.

Our AquaClean Formula is only available in our standard tip. Available in Green (AC2), Orange (AC3), Blue (AC4) and Yellow(AC5). Available in Standard-tip.

Solvent Washoff Ink

The Solvent Washoff Ink will flush off readily with a hot solvent spray such as in a degreaser. Solvent Washoff ink has a neutral solder flux base. The pigment in this ink may settle, so there is a “shaker” is each pen to keep it mixed. It is important that this ink be very thoroughly mixed to facilitate easy removal. This ink may be used to mark soldering errors. It may also be used for marking components. Put your mark beside the error -not on it or you will melt the pigment when you resolder. Solvent Washoff ink has a 3-4 month shelf life.

Solvent Washoff Ink is available in Red (SW1), Green (SW2), Orange (SW3), Blue (SW4),Yellow (SW5). Available in Standard-tip and Micro-tip.
