DESCRIPTION
-
Measure the insulation resistance up to 1 TΩ
The functional insulation resistance meter Sonel MIC-2501 surprises with numerous functions hidden in a neat and handy form. Due to its parameters, its robust casing with IP 65 protection level, its low battery power consumption and the possibility of recharging during measurements, the meter is a reliable tool that can be used in many areas. It is ideal for checking industrial installations and catenary networks and is also successfully used in residential buildings. The advantages of this equipment are especially appreciated by electricians working in maintenance, testing motors, cables and street lighting. The Sonel MIC-2501 meter is also useful for measurements during construction and maintenance of photovoltaic installations. It is a reliable solution created for the needs of telecommunications network installers and heating network operators, facilitating the control of the alarm system of pre-insulated pipes.
Product features
- measurement voltage within the range of 100…2500 V, selected in steps of 100 V
- continuous reading of measured insulation resistance or leakage current
- automatic discharge of the measured object’s capacitance upon completion of insulation resistance measurement,
- sound signaling of five-second time intervals, facilitating capture of time characteristics.
- timed measurement times T1 , T2 and T3 for measurement of absorption coefficients (Ab/PI/DAR) at 15, 60 and 600 s and polarization index
- reading of actual measurement voltage during measurement
- protection against measurement of live objects
Application
This insulation resistance meter is a device with a wide range of applications. It may be successfully operated both in residential construction industry and for inspecting industrial systems or traction networks. Due to its characteristics - excellent performance, low power consumption from batteries, the option of charging them during measurements, convenience of use and a high ingress protection level - it is often used by electricians working in maintenance teams, testing motors, cables, street lighting or at the construction and maintenance of photovoltaic systems. The device perfectly matches the needs of installers of telecommunications networks and operators of district heating networks, where the inspection of alarm system on insulated pipes is necessary.
Features
The meter may be used to measure the insulation resistance using the test voltage up to 2500 V. When testing the cables, it automatically discharges their load at the moment of completing the measurement. MIC-2501 allows user to measure the continuity of protective conductors and equipotential bondings with current exceeding 200 mA in both directions. The meter has a built-in voltmeter of AC and DC voltages in the range of up to 750 V. Extensive memory allows the device to record and send to a computer nearly 12,000 measurement results.
Capabilities
An important advantage of the device is its ability to a sufficiently long operation after one recharging of batteries. Electricians performing tests on repetitive objects or at short intervals do not have to worry about batteries discharging before completing the task. In addition, during the measurement work, the user may recharge device from an external power source, e.g. a power bank of 12 V/2 Ah.
