Kohlrausch Conductivity Bridge

The Kohlrausch Conductivity Bridge is a high-precision laboratory instrument developed for measuring the electrical conductivity and resistance of electrolyte solutions with exceptional accuracy. Manufactured by Micro Technologies, this bridge is widely used in physics laboratories, chemistry laboratories, engineering institutions, research organizations, and industrial quality control laboratories.

The instrument incorporates a precision circular slide wire calibrated from 0.01 Ohm to 10 Ohms, providing accurate bridge balancing and reliable conductivity measurements. A precision rotary multiplier dial offers six selectable multiplying factors of 0.1, 1, 10, 100, 1000, and 10000, allowing the instrument to measure a wide range of resistance values with excellent precision.

The bridge provides an impressive measurement range from 0.01 Ohm to 100 Kilo Ohms, making it suitable for determining the conductivity of various electrolyte solutions and performing advanced electrical resistance experiments.

Dedicated terminals are provided for connecting the power supply, headphones, or detectors, allowing convenient experimental setup. A separate detector key is also incorporated to simplify bridge operation during conductivity measurements.

The circular slide mechanism allows smooth adjustment of the balance point. The slider is positioned until the point of minimum sound or minimum AC signal is obtained, ensuring accurate null-point detection and precise measurement results.

The resistance coils used in the bridge provide an accuracy of ±0.1%, while the overall measurement accuracy is ±1% at mid-scale and ±2% overall, making the instrument suitable for precision laboratory work and research applications.

The complete assembly is housed in a premium Australian Pine wooden cabinet, providing excellent mechanical strength, long service life, and an attractive laboratory appearance. The compact tabletop design makes the instrument suitable for classroom demonstrations and research laboratories.

The Kohlrausch Conductivity Bridge is extensively used in engineering colleges, universities, chemistry laboratories, physics laboratories, instrumentation laboratories, research institutes, water analysis laboratories, industrial testing facilities, and quality control laboratories.

Every Kohlrausch Conductivity Bridge manufactured by Micro Technologies undergoes stringent quality inspection and calibration to ensure dependable performance, high accuracy, and long operational life.
