Meter Bridge or Wheatstone Bridge With Pencil Jockey Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10991
A Meter Bridge with a Pencil Jockey is a common physics lab
apparatus that applies the principle of the Wheatstone Bridge to accurately
measure an unknown electrical resistance. It features a uniform 1-meter wire,
known/unknown resistance gaps, a galvanometer, and a sliding contact (jockey)
shaped like a pencil to find the "null point" (zero galvanometer
deflection) for resistance calculation, proving Ohm's law and resistance
concepts
Designed for precision resistance determination and verification of bridge balance laws, this Four-Gap Meter Bridge is engineered for University and Secondary physics laboratories. Adhering to ISO 9001:2015 manufacturing protocols, the instrument features low-resistance copper conductors and a 24 SWG constantan wire for high-fidelity data acquisition in Wheatstone Bridge experimental modules, ensuring negligible end errors for calibrated measurements.

Key Pedagogical Outcomes
- Four-gap
copper strip configuration: Allows students to analyze complex
series and parallel resistance combinations using a singular bridge setup.
- 24
SWG constantan wire: Facilitates the calculation of unknown
resistance values by maintaining a linear relationship between length and
resistance minimizing error due to Joule heating.
- Removable
Copper Binding pieces: Enables learners to evaluate and
mitigate end-resistance errors, supporting advanced error analysis and
zero-correction calibration modules.
- Pencil Jockey with insulated lead: Supports the application of null-point detection techniques while preventing mechanical deformation or "kinking" of the bridge wire during repeated use.
International Logistics & Compliance
Science Lab Export ensures that all Meter Bridge units are prepared for high-volume global institutional distribution. Packaging utilizes export-grade seaworthy crating (ISPM-15 compliant) with anti-warp internal bracing to maintain the structural integrity of the laminated base during transcontinental transit. Documentation provided with each consignment includes the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and comprehensive Technical User Manuals in English. The chassis is a tropicalized design, tested for dimensional stability and adhesive integrity in operational environments reaching 45°C and 90% non-condensing humidity.
