Bosch GFM 1000-15 Professional Fork Meter

The Bosch GFM 1000-15 Professional Fork Meter provides fast and reliable electrical measurements for daily site work. Its open fork design allows electricians to measure AC current without breaking the circuit, which saves time during installation and maintenance tasks. As a result, users can complete checks quickly while maintaining safe working practices.

Built for demanding environments, the Bosch GFM 1000-15 combines strong protection with simple operation. The meter supports AC and DC voltage measurement up to 1000 V and AC current measurement up to 200 A. In addition, True RMS technology ensures stable readings when working with non-linear electrical loads.

Designed for Practical Electrical Testing

Electricians and HVAC engineers often work in confined spaces where standard meters can be difficult to use. The compact design of the Bosch GFM 1000-15 makes access easier in crowded panels and control cabinets. Meanwhile, the integrated non contact voltage detector helps identify live circuits before testing.

Clear readings are easy to view thanks to the inverted LCD display. The device also includes continuity testing, resistance measurement and frequency checks, which means a single tool can support many everyday diagnostics. Because of this versatility, the Bosch GFM 1000-15 Professional Fork Meter helps reduce the number of tools required on site.

Durable Construction for Jobsite Use

Durability is essential when tools are used daily on busy worksites. The Bosch GFM 1000-15 features IP54 protection against dust and splashes and is built to withstand accidental drops from heights of up to 2 metres. A comfortable grip further improves handling during long periods of use.

Additional features such as an integrated torch light, acoustic feedback and a magnetic hanging solution help improve efficiency while testing. With its robust construction and reliable measurement functions, the Bosch GFM 1000-15 offers dependable performance for installation, servicing and troubleshooting.
