Mô tả Sản phẩm

The MEGOHM 200 is a multi-purpose electronic resistance measurement instrument particularly suited for maintenance, verification and reception of telephone lines, and more generally of all low voltage cables.
It measures insulation resistance, loop resistance, AC and DC voltage and detects threshold crossings.

• Analogue and digital megohmmeter
• Analogue and digital continuity ohmmeter
• Adjustable test voltage from 50 to 500 V
• Rugged, lightweight and IP54 for onsite use
