EDTM R-CHEK+ (RC3175) Portable Handheld Surface Resistivity Meter with LCD Display - Four-Point Sheet Resistance Tester (0-199.9 ohms/sq) - Ideal for Conductive Coating Verification, Made in USA
Fast, Accurate Surface Resistivity Measurement — Pocket-Sized & 100% Made in the USA.
The RC3175 “R-CHEK +” Surface Resistivity Meter is a compact, budget-friendly tool designed for professionals who must confirm that thin films and coatings are applied correctly. Using the 4-point probe technique, it measures surface resistivity (sheet resistance) with precision, providing reliable quality-control verification across multiple industries. Pocket-sized portability. NIST-traceable calibration. Accurate 0–199.9 Ω/sq measurement range.
Why Professionals Rely on It - Surface resistivity is one of the most critical indicators of coating performance. The RC3175 ensures your coatings are applied correctly — whether on coated glass, solar cells, automotive mirrors, freezer doors, photonics components, or other specialty surfaces. Calibrated to standards traceable to a NIST-certified source, the meter delivers the accuracy needed for production, R&D, sales presentations, and quality assurance.
