Gossen Metrawatt METRAHIT 27EX-GMC-I Milliohmmeter

Overview

The Gossen Metrawatt METRAHIT 27EX-GMC-I is an intrinsically safe milliohmmeter designed for precision resistance measurement in hazardous locations. It employs Kelvin 4-wire measurement technology to eliminate lead resistance errors, making it ideal for testing interturn shorts, ground faults, and low-resistance circuits in industrial and maintenance applications.

Key Features

• Four measuring ranges: 30 mΩ, 300 mΩ, 3 Ω, 30 Ω
• Resolution: 10 µΩ on the lowest range
• Kelvin 4-wire measurement method for accurate, lead-independent readings
• Data Hold memory: stores up to 1200 measured values
• ATEX certification (Ex II 2 G EEx ia IIA T4) for use in hazardous areas
• Prototype test certificate: INERIS 05ATEX0040
• Includes DAkkS calibration certificate
• 3-year warranty on material and workmanship
