Measure insulation resistance up to 100 GΩ

The Sonel MIC-30 insulation resistance meter is a perfect response to the expectations of users who deal with the testing of insulation of electrical installations in a repeated manner, e.g. in single- and multi-family buildings, as well as in public utility buildings and small plants and workshops. The device enables the setting of the measurement voltage within the range from 50 V to 1000 V in 10 V steps, which makes it perfect for diagnosing electrical, control, telecommunications and ICT facilities.

Main features
measurement of insulation resistance up to 100 GΩ thanks to max 1000 V measurement voltage

designed for harsh environmental conditions conditions – IP67 ingress protection

excellent for repeatable measurements – memory of 12,000 records and UNI-Schuko adapter for sockets

allows for testing electrical continuity – R_CONT 200 mA function

checking start capacitors in motors thanks to capacity measurement function
…and much more
measurement voltage selected from: 50, 100, 250, 500, 1000 V or freely configurable within the range of 50…1000 V in steps of 10 V

Application

MIC-30 insulation resistance meter is perfectly suited for the needs of all users, who often examine the condition of electrical systems in single- and multi-family buildings as well as in public buildings and in small workshops or factories. With its test voltage settings from 50 V to 1000 V (in 10 V steps), the device is perfect for diagnosing the electrical, control, communication and telecommunications objects.

Features

Test voltage settings of 500 V or 1000 V perfectly match the requirements for assessing the protection of power supply lines but also of floors and walls in places where the insulation of the stand was used as a means of protection against electric shock – PRS-1 probe (optional accessory) is very useful for this purpose.

The dedicated UNI-Schuko adapter enables user to configure the tested cable pairs – this ensures quick and efficient inspection of the insulation resistance from the side of sockets.

With MIC-30 meter you can check whether an object is under voltage (measuring range up to 600 V), both in overhead and cable networks (measuring category of the device: CAT IV 600 V). You can verify the continuity of cables, e.g. PE connections and equipotential bonding – using the current of at least 200 mA, according to EN 61557-4. You can check the capacity of the start-up capacitors in household appliances and drives of any type (measuring range up to 10 µF). With the third socket (GUARD), you can verify the amount of leakage current, which may “escape” through faulty or contaminated insulation.

Built-in memory and wireless transmission ensure gathering and transmission of data to software that provides archiving and analysis (Sonel Reader). All of this makes MIC-30 meter an essential tool for every service technician.

Durable housing

Handy and ergonomic housing provides protection of IP67, ensuring reliability of the meter even in the harshest environmental conditions (moisture, dust, high temperature, etc.)
