Callender & Griffith's Bridge – V1

The Callender & Griffith's Bridge – V1 is a high-precision laboratory instrument developed for accurate resistance measurement and temperature determination using Platinum Resistance Thermometers (PRTs). Manufactured by Micro Technologies, this bridge is widely used for advanced experiments in electrical measurements, thermal engineering, instrumentation, and scientific research laboratories.

The instrument incorporates a precision 1×1 rotary resistance dial mounted on the front panel, providing a total resistance of 10 Ohms. This rotary dial enables smooth and accurate balancing of the bridge during measurement, ensuring excellent repeatability and precision.

A 1 Ohm circular slide wire is integrated into the instrument and is accurately calibrated into 100 equal divisions with a center-zero scale. The precision slide wire provides fine balancing capability for highly accurate resistance comparison and temperature measurement.

The bridge is equipped with four dedicated terminals, including two pairs of terminals marked C1 and P1, specifically designed for convenient connection of a Platinum Resistance Thermometer. Separate terminals are also provided for battery and galvanometer connections, simplifying experimental setup and ensuring reliable operation.

A convenient push-button key is incorporated to connect the battery into the measuring circuit whenever required, making bridge operation quick and user-friendly.

The instrument provides a high measurement accuracy of ±0.05%, making it suitable for precision laboratory work, calibration experiments, and research applications where dependable measurements are essential.

The complete bridge assembly is housed inside an attractive Australian Pine wooden cabinet, providing excellent durability, mechanical protection, and a professional laboratory appearance. The robust tabletop design is ideal for continuous use in educational institutions and research laboratories.

The Callender & Griffith's Bridge – V1 is extensively used in engineering colleges, universities, physics laboratories, thermal engineering laboratories, calibration laboratories, instrumentation laboratories, scientific research institutes, and industrial testing facilities.

Every Callender & Griffith's Bridge – V1 manufactured by Micro Technologies undergoes stringent quality inspection and calibration to ensure dependable performance, high precision, and long operational life.
