Compact and rugged - for service calls under harsh conditions and laboratory use

The METRISO INTRO fulfills all expectations and requirements for getting started with the premium class. Thanks to the included functions, it's especially well-suited for applications involving troubleshooting and inspection of electrical installations, as well as for use in service and industrial applications.

The insulation and resistance measuring instruments allow for quick and effective testing of protective measures in accordance with:

• DIN VDE 0100
• ÖVE-EN 1 (Austria)
• SEV 1000 (Switzerland)
• and regulations specific to other countries as well.

It's capable of executing all required electrical measurements and tests quickly and safely, in a retraceable fashion.

Insulation measurement per EN 61557-2 / VDE 0413 part 2
Low-resistance measurement per EN 61557-4 / VDE 0413 part 4
Voltage testing and measurement up to 1000 V
Measurement category 300 V CAT IV / 600 V CAT III

The insulation measuring instrument is suitable for the following applications:

• Measurement of insulation resistance at voltage-free devices and equipment, up to 1000 V
• Testing of the resistance of earthing, protective and equipotential bonding conductors
• Checking of test objects for absence of voltage
• Testing of floor covering electrostatic discharge capability (using shielded measurement cables) - EN 1081
• No. in Metrological Registry of Russian Federation: 73063-18

Simplifies your measuring tasks:

• Warning for hazardous shock voltages
• Quick test with red LED indicator on the instrument
• Acoustic signal generation in the event of limit value violations
• Measuring voltage: 250, 500 or 1000 V DC
• Measuring range: 10 kΩ ... 10 GΩ
• Low-resistance measurement: 0.01 ... 10 Ω with automatic polarity reversal
• Voltage measurement up to 1000 V AC TRMS / DC
• Electronic fuse for protection of the low-resistance measurement
