Bosch 0601077401 Professional GFM 1000-15 - MH 1 Fork Multimeter
Bosch Professional 0601077401 GFM 1000-15 MH 1 fork multimeter (True RMS, IP54)
Bosch 0601077401 is a Professional fork multimeter designed for fast, non-invasive electrical testing, letting you measure AC current via the open fork without needing to clamp around a cable. It’s a practical choice for electricians and HVAC technicians who want quicker checks in panels and tight spaces.
The GFM 1000-15 MH 1 also measures AC/DC voltage up to 1000V, plus continuity and resistance, with an inverted LCD display for clear readings. A built-in contactless voltage detector (NCV), torch and sound feedback help streamline fault-finding and verification tasks on site.
Key Features
- Fork current measurement: Measures AC current up to 200A through the open jaw for faster testing without measuring leads.
- AC/DC voltage measurement: Reads up to 1000V for common installation and maintenance checks.
- True RMS readings: Designed to improve measurement accuracy on AC signals.
- Contactless voltage detection (NCV): Helps identify the presence of voltage without direct contact.
- Inverted LCD display: Clear, high-contrast readout for quick interpretation.
- IP54 protection: Added resistance against dust and splashing water for demanding jobsite use.
- Integrated torch & sound feedback: Supports working in low light and provides audible confirmation during checks.
