High ohmic meters

High ohmic meters: Precise measurement of high resistances for reliable insulation tests

In many industrial and technical applications, the measurement of high resistances is of crucial importance, especially for the examination of insulation or the measurement of surface resistances. High ohmic meters are specialised measuring devices that are able to measure extremely high resistance values from kOhm to the gigaohm and teraohm range reliably and with the highest precision.

High-ohm measurement: measurement voltage, measurement current and dwell time
For precise resistance measurement, it is important to optimise the measuring voltage, the measuring current and the dwell time of the measurement. High resistance meters from burster offer fine tuning of these parameters to ensure exact and repeatable measurement results. The measuring voltage must be high enough to reliably measure small leakage currents, while the measurement current must be selected so that the device itself is not affected. A sufficient dwell time during the measurement ensures that all relevant parameters have stabilised before the measurement is completed.

Application of high-resistance measuring devices: Precision in insulation and surface resistance
The use of high-resistance measuring devices extends across a wide range of industrial sectors. One central field of application is testing the insulation of electrical components. Insulation measuring devices specialise in testing the dielectric strength of materials and ensuring that the insulation remains intact even at high voltages. This is particularly important in electromobility, high-voltage devices and cable manufacturing. In addition, high-ohmmeters are essential for measuring the surface resistance of materials, for example in electronics production or when testing antistatic materials.

High resistance meters and insulation testers: versatile tools for high resistances
In addition to their function as high-resistance meters, many of burster's devices can also be used as insulation testers. These insulation measuring devices test the insulation quality of components and systems by applying high voltages and measuring the leakage current flowing through the insulation material. This allows potential problems in the insulation to be detected at an early stage before expensive failures occur. This type of resistance measurement is particularly important in safety-critical areas.
