The Elcometer 127 Keane-Tator Surface Comparators & Magnifier (part numbers E127-1 to E127-4) provide a quick way to assess the surface profile of a blasted metal surface against reference profiles formed in corrosion-resistant metal. Confirming the profile is important because an incorrect profile compromises coating adhesion and coverage. The speed of the test makes it useful when going from blasting to painting quickly to avoid flash rust, and it can be used in hazardous areas where electronic equipment is prohibited.
Each comparator carries five profile grades ranging from 0.5 to 5.5 mils, with a hole in the centre so the blasted surface can be viewed directly through it for comparison. The comparators are designed for use with the Elcometer 127 illuminated x5 magnifier, which allows easy comparison of a single segment against the surface in detail; where visual assessment proves difficult, a tactile assessment by touch is possible.
Three profile types are offered to match the abrasive used: the Sand Comparator (E127-2) with 0.5, 1, 2, 3 and 4 mils; the Grit Comparator (E127-3) with 1.5, 2, 3, 4.5 and 5.5 mils; and the Shot Comparator (E127-4) with 2, 2.5, 3, 4 and 5.5 mils. The illuminated magnifier with integrated comparator holder is E127-1. The comparators conform to AS 3894.5, ASTM D 4417-A and SSPC PA 17. Used by coatings inspectors and blasting contractors in corrosion protection and industrial finishing. Supplied by BAMR, South Africa's authorised distributor.

Frequently asked questions
Which Elcometer 127 comparator do I need, sand, shot, or grit?
Choose the model matching your surface preparation method. The E127-2 is for sand blasted, E127-3 for grit blasted, and E127-4 for shot blasted surfaces. Each covers a different range of profile grades specific to that process.
What profile grades does each comparator cover?
E127-2 (sand) covers 0.5, 1, 2, 3, 4 mils. E127-3 (grit) covers 1.5, 2, 3, 4.5, 5.5 mils. E127-4 (shot) covers 2, 2.5, 3, 4, 5.5 mils. All models supply 5 reference profiles.
Can I use one comparator for multiple surface preparation types?
No. Each comparator is designed specifically for sand, grit, or shot blasted surfaces and covers a different profile range. Use the comparator matching your application's surface preparation method.
What is the magnifier (E127-1) and when would I use it?
The E127-1 is an illuminated x5 magnifier with an integrated comparator holder. Use it to examine profile details closely and keep your comparator securely positioned during inspection work.
Are the comparators and magnifier sold together or separately?
The comparators (E127-2, E127-3, E127-4) and magnifier (E127-1) are sold as separate units. You can use comparators alone or combine them with the magnifier for detailed inspection.
