Penetrant Testing – High Temperature Penetrant | Red & Fluorescent, Solvent & Water Removable 400ml MR68H

Product Description:

MR® 68 H – High-Temperature Red & Fluorescent Penetrant
The MR® 68 H is a solvent-removable Type III penetrant designed for demanding, high-temperature applications. Offering both visible red and (UV) red-fluorescent crack indications, it meets Sensitivity Level 2 per EN ISO 3452 standards.

Formulated for use between +50 °C and +200 °C, it’s ideal for in-service inspections of hot components without cooling downtime. Its hydrocarbon carrier medium ensures strong wetting properties on metallic surfaces, delivering crisp and reliable defect visibility under both daylight and UV inspection conditions.

Key Features:

• Dual Indication: Visible red for daylight, UV red-fluorescent for blacklight inspection

• High-Temperature Performance: Usable from +50 °C to +200 °C

• Type III Penetrant: Solvent-removable for efficient cleaning

• Sensitivity Level 2: Balanced flaw detection for general-purpose and in-service inspections
